Classification of Fats and Fatty Acids With Their Functions

Classification of Fats:

Fats are divided into two groups like animal fat and vegetable fat. These are discussed below:
 
What is Animal Fat Called?
Animal fats are lipid materials that are derived from animals. Physically, fats are solid and chemically, fats are composed of triglycerides. Animal fat-containing mainly saturated fatty acid and glycerol. Fats are generally obtained from livestock animals like pigs, chickens, and cows. Dairy products also yield popular animal fats products such as cheese, butter, and milk.

Sources of Animal Fats:

It includes-

  1. Milk and milk product,
  2. Eggs,
  3. Meat,
  4. Fish,
  5. Cod liver oil,
  6. Halibut liver oil,
  7. Sea fish like salmon fish, dark fleshed fish, herring’s fish, and sardine fish.

What is Vegetable Fat?

Vegetable fats are oil extracted from seeds, or less often, from other parts of fruits. As with animal fats, vegetable fats are the mixtures of triglycerides. Grape seed oil, soybean oil, and cocoa butter are examples of fats from seeds. In general usage, vegetable oil may refer exclusively to vegetable fats which are liquid at room temperature. Vegetable fats contain mainly unsaturated fatty acids and glycerol.
 
Sources of Vegetable Fats:
It includes-

  1. Seeds of grounds,
  2. Mustard oil,
  3. Sesame,
  4. Coconut oil,
  5. Palm oil,
  6. Delta,
  7. Corn oil and so on.

Main Functions of Fat in The Body:

All the major functions of fat have listed in the following:

  1. It supplies energy (9 kcal/gm).
  2. It supplies essential fatty acids.
  3. It carries (act as a vehicle) fat-soluble vitamins– A, D, E, K.
  4. It provides flavor to food.
  5. It makes the food palatable and stimulates the secretion of digestive juices and thereby helps indigestion.
  6. It stimulates the secretion of the hormone enterogastrone and thereby reduces appetite.
  7. It stimulates the secretion of bile and so it acts as a cholagogue.
  8. Cholesterol is a component of hormones of the ovary, testes, and adrenal cortex.
  9. Phospholipids help in the formation of cell membranes.
  10. It provides support to the viscera.
  11. It protects cold-act as a cushion and insulator.
  12. It maintains the decency of the body and beautifies the body configuration.

Classification of Fatty Acids:

Fatty acids are divided into two major groups, saturated fatty acids are one of those. The other one is unsaturated fatty acids. These are explained below:
 
What are Saturated Fatty Acids?
Saturated fatty acids contain a single bond of carbon. Common saturated fatty acids are palmitic acid, stearic acid, and butyric acid.

What are Unsaturated Fatty Acids?

Unsaturated fatty acids are oleic acid, linolenic acid, and arachidonic acid. Arachidonic acid is present in animal fat. Linoleic acid is present in vegetable fat.
