Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which are the building blocks of most lipid molecules?
A
glucose and protein
B
glucose and fatty acids
C
fatty acids and glycerol
D
amino acids and glycerol
Explanation: 

Detailed explanation-1: -Triacylglycerols are the main form of lipid found in the body and in the diet. Fatty acids and glycerol are the building blocks of triacylglycerols.

Detailed explanation-2: -Glycerol and fatty acids are the basic building blocks of fats (lipids).

Detailed explanation-3: -Fatty acids and glycerol are the building blocks of triglycerides. Glycerol is a thick, smooth, syrupy compound that is often used in the food industry. To form a triglyceride, a glycerol molecule is joined by three fatty acid chains.

Detailed explanation-4: -Fatty acids are the building blocks of the fat in our bodies and in the food we eat. During digestion, the body breaks down fats into fatty acids, which can then be absorbed into the blood. Fatty acid molecules are usually joined together in groups of three, forming a molecule called a triglyceride.

Detailed explanation-5: -The building blocks of lipids are one glycerol molecule and at least one fatty acid, with a maximum of three fatty acids. Glycerol is a sugar alcohol with three OH groups. It acts as a backbone for fatty acids to bond. Fatty acids are made up of a long hydrocarbon with carboxyl group, which is represented as COOH.
