Building blocks of lipids
A
monosaccharides
B
glycerol and fatty acids
C
neucleotides
D
amino acids
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Fatty acids are important building blocks of lipids and they give a diversity and chemical specificity to the complex lipids found in natural fats and oils, comparable to that given by the amino acids to proteins.

Detailed explanation-3: -Triglycerides are simple lipid which constituted one molecule of glycerol and three molecules of fatty acids. Triglyceride is the storage form of lipid, which is used for energy production. Triglycerides are found circulating in the blood where they are transported by very-low-density lipoprotein (VLDL).
