LEARNING OBJECTIVES:
At the end of the lesson, the students are expected to:
a.describe Biomolecules;
b.classify Biomolecules, and;
c.discuss Carbohydrates and Lipids.

“VIEW ME”
Direction: Watch a video
presentation about
biomolecules take down
notes.

“CROSSWORD”
Direction: Read the clues. After all the clues are answered,
fill in the crossword puzzle.
HORIZONTAL
2.It is great at storing energy
3. It is also known as Macromolecule, that
means large molecule
5. Basic unit of carbohydrate
VERTICAL
1. Provides quick energy to humans
4.Most known and abundant example of
carbohydrates

• also called biological molecule
• any of numerous substances that are
produced by cells and living organisms.
• Biomolecules have a wide range of sizes
and structures and perform a vast array of
functions.
BIOMOLECULES

The Four Classes
of Biomolecules

 Carbohydrates
 Lipids
 Nucleic Acids
 Proteins

CARBOHYDRATES
• the major source of energy for the
body
• are found in a wide array of both
healthy and unhealthy foods
(CH2O)n
n= number of molecules

We get 4 kilocalories per gram
of carbohydrates that we eat!

• All carbohydrates contains carbon, hydrogen, and
oxygen. (C-H-O)
• Carbohydrates can be classifies into:
MONOSACCHARIDES DISACCHARIDES POLYSACCHARIDES

MONOSACCHARIDES
• From the prefix "mono" which means one,
monosaccharides is the simplest sugar and the basic
subunits of carbohydrates.
• These compounds are white solid at room temperature
• They have polar, hydroxyl groups’ intermolecular
structures, they are very soluble in water.
C6H12O6

GLUCOSE - also called dextrose
The main type of sugar in the blood
and the most abundant
monosaccharide.
It is very important to have a steady
supply of glucose in the blood to
maintain body functions.
Blood Sugar

GLUCOSE - also called dextrose
 When too much glucose is in the blood, the pancreas
secretes a hormone called insulin which stimulates cells
in the liver, muscles and fat to absorb glucose and
transform it into glycogen or fats, which can be stored for
a period of time.
 When blood glucose drops, the pancreas secretes
glucagon, which cause liver, muscles and fat to convert
glycogen back to glucose.

Is it is a naturally occurring sugar,
found primarily in fruits like
grapes, apple, or atis.
It also occurs naturally in other
plants foods such as sugar beets,
sugar cane honey, and vegetables.it
is considered as the sweetest
naturally occurring sugar.
FRUCTOS
E
- also known as fruit sugar

DISACCHARIDES
Also known as double sugar, is the sugar formed
when two monosaccharides are joined.
Like monosaccharides, disaccharides are simple
sugars soluble in water.
CH12H22O11

SUCROSE - are table sugar
 Consisting of one glucose and one fructose
molecule.
 It is naturally occurring carbohydrates found
in many fruits, vegetables and grains, but it is
also added to many processed food such as
candy, ice cream, breakfast, cereals, canned
foods, soda and other sweetened beverages.

LACTOSE
is sugar found only in milk
also present in dairy products and
products made from milk, including
cheese and ice cream
consisting of glucose and galactose

MALTOSE
 is a sugar made out of two glucose molecules
bound together.
 It’s created in seeds and other parts of plant as
they break down their stored energy in order to
sprout. Thus, foods like cereals, certain fruits and
sweet potatoes contain naturally high amount of
this sugar.

POLYSACCHARIDES
 Is also known as complex carbohydrates
 From prefix “poly” meaning many, are large molecules that
are made up of many smaller units that are joined together.
The three common polysaccharides are: starch, glycogen, and
cellulose.
(C6H10O5)n

STARCH
is a soft, white, tasteless powder
that is insoluble in cold water,
alcohol water, alcohol or other
solvents and is produced by all
green plants.

GLYCOGEN
is a polysaccharide that is similar to
starch.
it is also composed of alpha glucose units.
It differs from starch since glycogen
shows a higher degree of branching and is
polysaccharide that is made by animals.

CELLULOSE
is a molecule, consisting of hundreds-
and sometimes even thousands of
carbon, hydrogen and oxygen atoms.
is the main substance in the wall of
plants cells, helping plants to remain
stiff and upright.

Human cannot digest cellulose, but it is important
in diet as fiber.
When we eat food rich in fiber, which is cellulose,
it speeds the movement of food through the
digestive tracts.

FATS OR LIPIDS
 Another class of biochemical that has the job of storing
energy for later use.
 Are also found in hormones and cell membrane
components. They are molecules that contain hydrocarbons
and make up the building blocks of the structure and
functions of living cells.

Provide mechanical
protection for the internal
organs of the body and
serves as waterproof
covering in some plants and
animals.

Triglycerides - The most abundant of the lipids are the fats
and oils.
 Fats are solids at room temperature and contain
saturated fatty acids and produced only by animals.
Examples of animal fats are lard and butter.
 Oils are liquids at room temperature and contain
unsaturated fatty acids. Most oils, such as vegetable
oil, corn oil, and olive oil are produced by plants.

“PICK ME”
Direction: Pick a paper in the box, among them
contains questions written on it. Whoever
has the paper with question will have to
analyze and give the correct answer.

Direction: Answer the following questions briefly. Write
you answer in a 1 whole sheet of paper. (5pts Each)
1.What are biomolecules?
2.What are the four classes of Biomolecules?
3.What are Carbohydrates and Lipids? Discuss each.
