1. Triglyceride,
They are commonest form of lipids in nature.
Triglycerides formed by esterification of one glycerid molecule and three fatty acid molecule.
Triglyceride are hydrolyzed by lipase enzyme.
Hydrolysis of lipids called saponification .
There are two types of triglycerides,
*1. Saturated triglycerides
*2. Unsaturated triglycerides
Unsaturated facts can be converted into saturated fact by hydrogenation.
Functions of triglycerides,
*They can use as an energy source and storage food
*Triglycerides are thermal insulators
*Protect internal organs from mechanical shocks and friction
2. Phosphor lipids
Phosphor lipids formed by esterification of two fatty acid molecules and phosphoric acid molecule with glycerol molecule
3. Steroids
Steroids are having several rings of carbon.
Cholesterol is the most abundant steroid in human body.
4. Waxes
Waxes are composed of fatty acids and alcohol which contain lone hydrocarbon chain.
Waxes are extremely hydrophobic therefore they can act as water proof waxes and waxes can reduce water loss.
5. Spingo lipids
Spingo lipids are present in plasma membrane.
This compound play important role in single transmission and cell recognition.
6. Glycolipids
They are composed of lipids and polysacharides
They can be found in plasma membrane
7. Lipoprotein
They contain both proteins and lipids .
It allows facts to move through the water,inside and out side of the surface .
They are also present in blood plasma.
Functions of lipids
*Lipids act as stored food
*Lipids act as vitamins
*Lipids act as hormones
*Lipids act as an electrical insulator
*Lipids help to reduce the body temperature
*Protect internal organs from mechanical shocks and friction
