Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The building block of a Lipid is a ____
A
fatty acid
B
saccharide
C
sugar
D
amino acid
Explanation: 

Detailed explanation-1: -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-2: -Lipids are an essential component of the cell membrane. The structure is typically made of a glycerol backbone, 2 fatty acid tails (hydrophobic), and a phosphate group (hydrophilic).

Detailed explanation-3: -Fats are actually a type of lipid. Lipids are a major class of biochemical compounds that includes oils as well as fats. Organisms use lipids to store energy and for many other uses. Lipid molecules consist mainly of repeating units called fatty acids.

Detailed explanation-4: -Since fatty acids are the building blocks of lipids such as fats, cholesterol and lipoproteins, they also take up the physical characteristics of fatty acids. A little more should we know about fatty acids. As seen in the above structure of palmitic acid, all bonds in the alkyl group (hydrocarbon chain) are single.
