Biochemistry emerged as a separate discipline when scientists combined biology with organic, inorganic, and physical chemistry. They began to study areas such as:
How living things get energy from food
The chemical basis of heredity
What fundamental changes occur in disease
Biochemistry includes the sciences of molecular biology, immunochemistry, and neurochemistry, as well as bioinorganic, bioorganic, and biophysical chemistry.
What do biochemists do?
Biochemists interact with scientists from a wide variety of other disciplines, usually on problems that are a very small piece of a very large and complex system.
Biochemists in industry are interested in specific applications that will lead to marketable products
Biochemists in academia or government labs conduct more basic and less applied research
Where is biochemistry used?
Biochemistry has obvious applications in medicine, dentistry, and veterinary medicine. Other applications include:
Food Science
Biochemists determine the chemical composition of foods, research ways to develop abundant and inexpensive sources of nutritious foods, develop methods to extract nutrients from waste products, and/or invent ways to prolong the shelf life of food products.
Agriculture
Biochemists study the interaction of herbicides/insecticides with plants and pests. They examine the structure–activity relationships of compounds, determine their ability to inhibit growth, and evaluate the toxicological effects on surrounding life.
Pharmacology, Physiology, Microbiology, Toxicology, and Clinical Chemistry
Biochemists investigate the mechanisms of drug actions; engage in viral research; conduct research pertaining to organ function; or use chemical concepts, procedures, and techniques to study the diagnosis and therapy of disease and the assessment of health.

This document provides an overview of biomolecules and biochemical reactions in living cells. It discusses that there are four main classes of biomolecules - carbohydrates, lipids, proteins, and nucleic acids. These biomolecules are made up of smaller building blocks like amino acids, fatty acids, and sugars. Biomolecules come together to form larger macromolecules through processes like dehydration synthesis. Biochemical reactions in cells include catabolic reactions that break down molecules to release energy and anabolic reactions that use energy to synthesize biomolecules. These reactions are catalyzed by enzymes and allow cells to maintain order through processes such as transport, movement, and waste removal.
Water is the most abundant and important molecule in cells and tissues, composing about two-thirds of the human body. It acts as both the solvent for biochemical reactions and as a reactant or product in thousands of reactions. Water also forms hydrogen bonds with polar groups of cellular constituents.
Proteins consist of amino acid residues and range widely in length from small peptide hormones of nine residues to large structural proteins over 25,000 residues. The specific sequence of amino acid residues gives each protein its unique properties.
Carbohydrates are biomolecules made of carbon, hydrogen and oxygen. They include sugars, starch and cellulose and are divided into monosaccharides, disaccharides, oligosaccharides and polysaccharides based
Carbon has unique bonding properties that allow it to form many different compounds. It can form single, double, or triple bonds with itself and other elements. The four major forms of pure carbon are diamond, graphite, fullerenes, and nanotubes. Organic compounds contain carbon, and hydrocarbons are organic compounds made of only carbon and hydrogen. The four main classes of organic macromolecules that make up living things are carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates and lipids are used for energy storage, while proteins and nucleic acids have structural and information-storing roles in the body.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. CHEMISTRY OF LIFE
• Elements: simplest form of a
substance - cannot be broken down
any further without changing what it is
• Atom: the actual basic unit -
composed of protons, neutrons, and
electrons
3.
4. THE ATOM
• Just like cells are the basic unit of life, the
ATOM is the basic unit of matter.
• They are very small. If placed side by side
one million would stretch a distance of 1cm.
• The atom is made up of 3 particles.
Particle Charge
PROTON +
NEUTRON NEUTRAL
ELECTRON -
5. • Electrons are not present within the atom,
instead THEY REVOLVE AROUND THE
NUCELUS OF THE ATOM & FORM THE
ELECTRON CLOUD
• Draw a helium atom. Indicate where the
protons, neutrons and electrons are.
NEUTRONS
PROTONS
- ATOMIC # = 2
+ +
(PROTONS)
ELECTRONS -
ATOMIC MASS = 4
(PROTONS &
NEUTRONS)
6. ISOTOPES
• atoms of the same element that HAVE A
DIFFERENT NUMBER OF NEUTRONS
• Some isotopes are radioactive. This means
that their nuclei is unstable and will break
down at a CONSTANT RATE over time.
• There are several practical uses for
radioactive isotopes:
1. CARBON DATING
2. TRACERS
3. KILL BACTERIA / CANCER CELLS
7. COMPOUNDS
• a substance formed by the chemical
combination of 2 or more elements in definite
proportions
– Ex: water, salt, glucose, carbon dioxide
8. • The cell is a COMPLEX CHEMICAL
FACTORY containing some of the same
elements found in the nonliving
environment.
• (C) carbon, (H) hydrogen, (O) oxygen &
(N) nitrogen are present in the greatest
percentages
9. TWO TYPES OF
COMPOUNDS
• Organic - Contain C, H, and O in some
ratio (usually referred to as chemicals of
life)
– Carbohydrates, Proteins, Lipids, Nucleic Acids
• Inorganic - usually "support" life - no
specific ratio of C, H, and O
– Water (H2O), Carbon Dioxide (CO2)
10. CHEMICAL BONDS
• Chemical bonds hold the atoms in a
molecule together.
• There are 2 types of HIGH ENERGY
chemical bonds - IONIC and COVALENT
11. IONIC BONDS
• Occur when 1 or more electrons are
TRANSFERRED from one atom to another.
• When an atom loses an electron it is a
POSITIVE charge.
• When an atom gains an electron it is a
NEGATIVE charge
• These newly charged atoms are now called
IONS
– Example: NaCl (SALT)
12.
13. COVALENT BONDS
• Occur when electrons are SHARED by atoms.
• These new structures that result from covalent
bonds are called MOLECULES
• ** In general, the more chemical bonds a
molecule has the more energy it contains
SHARING IS CARING!
14. MIXTURES
• Water is not always pure. It is often found as
part of a mixture.
• A mixture is a material composed of TWO OR
MORE ELEMENTS OR COMPOUNDS THAT
ARE PHYSICALLY MIXED
– Ex: salt & pepper mixed, sugar and sand – can be
easily separated
15. SOLUTION
Two parts:
• SOLUTE – SUBSTANCE THAT IS BEING
DISSOLVED (SUGAR / SALT)
• SOLVENT - the substance in which the solute
dissolves
• Materials that do not dissolve are known as
SUSPENSIONS.
– Blood is the most common example of a
suspension.
– Cells & other particles remain in suspension.
16. FORMULA
• The chemical symbols and numbers that
compose a compound ("recipe")
• Structural Formula – Line drawings of the
compound that shows the elements in
proportion and how they are bonded
• Molecular Formula – the ACTUAL formula
for a compound
C2H6O
17. ACIDS & BASES
• Acids: always (almost) begin with "H" because
of the excess of H+ ions (hydrogen)
– Ex: lemon juice (6), stomach acid (1.5), acid rain
(4.5), normal rain (6)
Facts about Acids
• Acids turn litmus paper RED and usually taste
SOUR.
• You eat acids daily (coffee, vinegar, soda,
spicy foods, etc…)
18. ACIDS & BASES
• Bases: always (almost) end with -OH because
of the excess of hydroxide ions (Oxygen &
Hydrogen)
– EX: oven cleaner, bleach, ammonia, sea water,
blood, pure water
Facts about Bases
• Bases turn litmus BLUE.
• Bases usually feel SLIPPERY to touch and
taste BITTER.
20. pH SCALE
• measures degree of
substance alkalinity or
acidity
• Ranges from 0 to 14
• 0 – 5 strong acid
• 6-7 neutral
• 8-14 strong base
21. • The goal of the body is to maintain
HOMEOSTASIS (neutrality) – to do this when
pH is concerned, we add weak acids & bases to
prevent sharp changes in pH.
• These are called BUFFERS
22. And now for the
Biochemistry portion of
things….
23.
24. CARBOHYDRATES
• Living things use carbohydrates as a key source
of ENERGY!
• Plants use carbohydrates for structure –
CELLULOSE give structure to the Cell Wall
– include sugars &complex carbohydrates (starches)
– contain the elements carbon, hydrogen, and oxygen
(the H is in a 2:1 ratio to the O)
25. Monosaccharides (simple sugars)
• all have the formula C6 H12 O6
• all have a single ring structure
– (glucose is an example)
27. Polysaccharides
(formed of three or more simple sugar units)
• Glycogen - animal starch stored in liver & muscles
• Cellulose - indigestible in humans - forms cell walls
• Starches - used as energy storage
29. Dehydration Synthesis
• Combining simple molecules to form a more complex
one with the removal of water
monosaccharide + monosaccharide ---> disaccharide + water
C6H12O6 + C6H12O6 -----------------> C12H22O11 + H2O
• Polysaccharides are formed from repeated
dehydration synthesis of water
– They are the stored extra sugars known as starch
30. Hydrolysis
• Addition of WATER to a compound to SPLIT it
into smaller subunits
– (also called chemical digestion)
disaccharide + H2O ---> monosaccharide + monosaccharide
C12 H22 O11 + H2 O ------------> C6 H12 O6 + C6 H12 O6
31.
32. Lipids (Fats)
• Fats, oils, waxes, steroids
• Chiefly function in energy storage, protection,
and insulation
• Contain carbon, hydrogen, and oxygen but the
H:O is not in a 2:1 ratio
• Tend to be large molecules -- an example of a
neutral lipid is below
33. • Neutral lipids are formed from the union of one glycerol
molecule and 3 fatty acids
• 3 fatty acids + glycerol ----> neutral fat (lipid)
• Fats -- found chiefly in animals
• Oils and waxes -- found chiefly in plants
• Oils are liquid at room temperature, waxes are solids
• Lipids along with proteins are key components of cell
membranes
• Steroids are special lipids used to build many
reproductive hormones and cholesterol
34. PROTEINS
• contain the elements carbon, hydrogen, oxygen, and
nitrogen
• composed of MANY amino acid subunits
• It is the arrangement of the amino acid that forms the
primary structure of proteins.
• The basic amino acid form has a carboxyl group on
one end, a methyl group that only has one hydrogen
in the middle, & an amino group on the other end.
• Attached to the methyl group is a R group.
35. AN R GROUP IS ANY GROUP
OF ATOMS – THIS CHANGES
THE PROPERTIES OF THE
PROTEIN!
37. FUNCTIONAL GROUPS
• There are certain groups of atoms that are
frequently attached to the organic molecules we
will be studying, and these are called functional
groups.
• These are things like hydroxyl groups which
form alcohols, carbonyl groups which form
aldehydes or ketones, carboxyl groups which
form carboxylic acids, and amino groups
which form amines.
38.
39. Dipeptide
• formed from two amino acid subunits
• Formed by the process of Dehydration Synthesis
• amino acid + amino acid dipeptide + water
40. Hydrolysis of a dipeptide
• Breaking down of a dipeptide into amino acids
• dipeptide + H2O ---> amino acid + amino acid
41. Polypeptide (protein)
• composed of three or more amino acids linked by
synthesis reactions
• Examples of proteins include insulin, hemoglobin,
and enzymes.
• ** There are an extremely large number of
different proteins. The variability include
differences in the number, kinds and
sequences of amino acids in the proteins
42. NUCLEIC ACIDS
• in all cells
• composed of NUCLEOTIDES
• store & transmit heredity/genetic information
• Nucleotides consist of 3 parts:
• 1. 5-Carbon Sugar
• 2. Phosphate Group
• 3. Nitrogenous Base
– A, T, G, C
43.
44.
45. DNA (deoxyribonucleic acid)
• contains the genetic code of instructions that direct a
cell's behavior through the synthesis of proteins
• found in the chromosomes of the nucleus (and a few
other organelles)
46. RNA (ribonucleic acid)
• directs cellular protein synthesis
• found in ribosomes & nucleoli
• Nitrogenous Bases – (A, U, G, C)
47. CHEMICAL REACTIONS
• a process that changes one set of chemicals into
another set of chemicals
• REACTANTS – elements or compounds that
enter into a chemical reaction
• PRODUCTS – elements or compounds that are
produced in a chemical reaction
• Chemical reactions always involve the breaking of
bonds in reactants and the formation of new
bonds in products.
48. • In a reaction, energy is either TAKEN IN
(ENDOTHERMIC) or GIVEN OFF
(EXOTHERMIC)
• Can you think of an everyday example of
each type of reaction?
49. Enzymes and Enzyme Action
• catalyst: inorganic or organic substance which
speeds up the rate of a chemical reaction without
entering the reaction itself
• enzymes: organic catalysts made of protein
• most enzyme names end in -ase
• enzymes lower the energy needed to start a
chemical reaction. (activation energy)
• begin to be destroyed above 45oC. (above this
temperature all proteins begin to be destroyed)
50. It is thought that, in order for an enzyme to affect the rate of a
reaction, the following events must take place.
1. The enzyme must form a temporary association with the
substance or substances whose reaction rate it affects.
These substances are known as substrates.
2. The association between enzyme and substrate is thought to
form a close physical association between the molecules and
is called the enzyme-substrate complex.
3. While the enzyme-substrate complex is formed, enzyme
action takes place.
4. Upon completion of the reaction, the enzyme and product(s)
separate. The enzyme molecule is now available to form
additional complexes.
51. How do enzymes work?
• substrate: molecules upon which an enzyme acts
• the enzyme is shaped so that it can only lock up
with a specific substrate molecule
enzyme
substrate -------------> product
52. "Lock and Key Theory"
• each enzyme is specific for one and ONLY one
substrate (one lock - one key)
• this theory has many weaknesses, but it
explains some basic things about enzyme
function
53. Factors Influencing Rate of
Enzyme Action
1. pH - the optimum (best) in most living things is
close to 7 (neutral)
• high or low pH levels usually slow enzyme activity
• A few enzymes (such as gastric protease) work
best at a pH of about 2.0
54. 2. Temperature - strongly influences enzyme
activity
• optimum temperature for maximum enzyme
function is usually about 35-40 C.
• reactions proceed slowly below optimal
temperatures
• above 45 C most enzymes are denatured
(change in their shape so the enzyme active site
no longer fits with the substrate and the enzyme
can't function)
55.
56. 3. Concentrations of Enzyme and Substrate
• ** When there is a fixed amount of enzyme and
an excess of substrate molecules -- the rate of
reaction will increase to a point and then level
off.
