6.  Generally hydrophobic substances and are insoluble in water but
soluble in organic solvents, such as benzene, ether, and chloroform.
 Contains less oxygen in
proportion to hydrogen.
Example: Tristearin, the primary
fat in beef, has the formula
C57H110O6

7. 1. Solvent for
fat-soluble
vitamins and
hormones.

8. 2. Prevents
water loss
from skin
surface.

9. 3. Essential parts of cell structures such
as cell membrane.

10. 4. Insulating material.

11. 5. Source and storage of energy.

13. Lipids composed of one
molecule of glycerol (an
alcohol containing 3
carbon) and three fatty
acid molecules.

14. 3 molecules of water are needed to break one
molecule of fat with the aid of an enzyme called
lipase.

15. Saturated fatty acids
- Solid at room
temperature. Mostly
found in animals.
Unsaturated fatty acids
- Liquid at room
temperature. Mostly
found in plants.

17. Important component of
cell membranes

18. Serves as covering for leaves
and stems of plants, and on
the skin and fur of some
animals.

19. Lipids with a carbon skeleton
of four fused rings.
Example: cholesterol, bile salts,
sex hormones, and vitamin D

20. Also known as blood
fats

21. Serves as surfactant that
help reduce tension on the
lungs to maintain its right
shape.

24.  Organic compounds that function for storage of genetic
information.
 They carry the code needed in the formation of specific
proteins (protein synthesis)
Nucleic acids
Deoxyribonucleic
acid
Ribonucleic
acid

26.  Basic building blocks:
nucleotide
Nucleic acids
Deoxyribonucleic
acid
Ribonucleic
acid
 A nucleotide is made up of a five-
carbon sugar, phosphate group, and
nitrogenous base.

27.  There are two families of nitrogenous base.
