Question

Triglycerides look like the letter "E" because they contain the following components

a. Four fatty acid chains, a glycerol and a phosphate group
b. Two fatty acid chains, a simple sugar and a nitrogenous base
c. Three fatty acid chains and a 'backbone' of glycerol
d. Three 6-carbon rings attached to one 5-carbon ring ("3 bedrooms and a bath")

Answer 1

c. Three fatty acid chains and a 'backbone' of glycerol

Step-by-step explanation:

A triglyceride is ester which is derived from glycerol and three (may be different or same) fatty acids. The name is thus derived as tri ( 3 fatty acids) - and glyceride (glycerol backbone). Triglycerides are main constituents of the body fat in human body and other vertebrates.

Triglycerides are the tri-esters which consist of glycerol attached to 3 molecules of fatty acid. Alcohols consists of hydroxyl group. Organic acids consists of carboxyl group. Alcohols and organic acids join to form esters. The molecule of glycerol has 3 hydroxyl groups which are bonded to three fatty acid molecules via ester bonds.
