Question

A significant use of triglycerides in the body is triglycerides can be used to break down both carbohydrates and proteins triglycerides can be made into insoluble fibers because they cannot be broken down by enzymes in our body triglycerides are the most high concentrated form of chemical energy triglycerides can be converted into carbohydrates and proteins as needed.true/false

Answer 1

The given statement is true.

Step-by-step explanation:

• The chemical structure of triglycerides includes:

1. A glycerol molecule attached with ester bonds to,
2. Three fatty acid chains.

• Among all the bio-molecules available in the cells, triglycerides store the maximum energy, due to the presence of long carbon chains with single (saturated) or double/triple (unsaturated) bonds.
• One gram of triglyceride can store about 38 kJ of energy which is double the amount that can be stored in carbohydrates.
• During metabolism, these molecules are hydrolysed by enzymes called lipases, those are secreted by the pancreas, into fatty acids, mono- and di-glycerides, by the process of lipolysis.
• Bile in the intestine further promotes the action of lipases.
• These digested components are absorbed into the duodenum through the enterocyte cells where they associate with proteins and cholesterol to form chylomicrons.
• These chylomicrons are released into the lymphatic system and from there cells of various organs can absorb them for storage or hydrolysis.
• The triglycerides are used in the cells for energy by hydrolysing them using cell specific lipases to fatty acid and glycerol.
• The glycerol is used to produce glucose and the fatty acids are further hydrolysed or converted to ketone from which amino acids can be formed.
