3. WHAT IS
LIPIDS?
01

4. ❖ Make food oily
❖ Keeps our body warm
❖ prevent the watery component of the cell
from leaking out.

5. What does lipids include?
FATS OILS WAXES STEROIDS &
PHOSPOLIPIDS

6. FATS and OILS
THREE MAIN TYPES of LIPIDS
01
02
03
PHOSPHOLIPIDS
STEROIDS

7. Serves as nutrient reserves in
animals and plants.
FATS and OILS ➔ Corn oil, canola oil and olive oil
➔ This lipids has yellowish color and are in
liquid form at room temperature.
Lard and butter are made from typical
animal fats
➔ They usually have whitish color and are
solid at room temperature.

8. GLYCEROL
TWO BASIC UNITS of FATS and OILS
01
02
FATTY ACIDS

9. A three - carbon alcohol with three
hydroxyl groups attached to each
carbon.
GLYCEROL

10. Are long-chain aliphatic carboxylic acid
products which result from hydrolysis of
lipids
FATTY ACIDS
➔ short, medium, or long-chain fatty acid

11. These are the three fatty acids are joined
to one molecule of glycerol, the fats and
oil of it are called TRIGLYCERIDES.
TRIGLYCERIDES
➔ Animals are composed high proportions
of saturated fatty acids in which all the
carbon atoms of the fatty acids are
bonded to at least two hydrogen atoms.

12. It consists a glycerol molecule, a
phosphate group, and two fatty acids.
PHOSPHOLIPIDS
➔ Phosphate group are water soluble while
the rest of the molecule is insoluble in
water.
➔ Cell membrane surrounds every cell that
are made of bilayer of phospholipids.
➔ Lecithin, cephalin, plasmalogen, and
lipositol

13. Are organic compound with four rings
arranged specific configuration.
STEROIDS
➔ Sterols and terpenes
➔ STEROLS - such as cholesterol,
androgens, ans estogens(sex
hormones), adrenal corticosteroids,
ergosterol, and 7 dehydrocholesterol
