2. WHAT ARE BIOMOLECULES?
Molecules are groups of atoms
that contain more than one element
and biomolecules involves in
maintenance and metabolic
processes of living organisms
Elements are atoms of one
particular type (from the periodic
table)

4. TYPES OF BIOMOLECULES
Carbohydrates
Lipids
Proteins
Nucleic acids

5. Made up of C,H,O
Function: source of energy
Examples: sugar, rice, apples,
bread
Polymer: polysaccharide
(carbohydrates)
Monomer: monosaccharide
1. CARBOHYDRATES

6. TYPES OF CARBO HYDRATES
1. Monosaccharides: single sugar.
Ex. Glucose, fructose, galactose
Aka – simple sugars
2. Disaccharide: 2 simple sugars
Ex. Sucrose (table sugar) maltose
3. Polysaccharides: 3 or more sugars
Ex. Cellulose – used in cell walls
Starch stores energy in plants
Glycogen – stored energy in animals

7. 2. LIPIDS
Made of C,H,O
Function: Store energy
Examples: wax, oil, butter,
cholesterol
Structure: 1 glycerol and 3 fatty
acids

8. EXAMPLES OF LIPIDS

9. 3. PROTEINS
Made of C,H,O,N
Function: Building and repairing cells,
speeds up or slows down chemical
reactions
Examples: meat/muscle, hair, nails,
enzymes
Polymer: Polypeptide (proteins)
Monomer: amino acid

10. EXAMPLE OF PROTIEN

11. 4. NUCLEIC ACIDS
Made of C,H,O,N,P
Function: Store genetic
information, determines physical
appearance
Example: DNA, RNA, ATP
(energy)
Polymer: nucleic acids
Monomer: nucleotides
