Biology Question on Biochemistry
Which of the following are not fatty acids?
A. Glutamic acid
B. Arachidonic acid
C. Palmitic acid
D. Lecithin
E. Aspartic acid
Choose the correct answer from the options given below :
A
C, D and E only
B
A and B only
C
A, D and E only
D
B and C only
Answer
A, D and E only
Explanation
Solution
Fatty acids: Are long-chain carboxylic acids. Palmitic acid (C) and arachidonic acid (B) are examples of fatty acids.
Amino acids: Glutamic acid (A) and aspartic acid (E) are amino acids, the building blocks of proteins. They are not fatty acids.
Phospholipid: Lecithin (D) is a type of phospholipid, a major component of cell membranes. While fatty acids are part of the structure of lecithin, lecithin itself is not a fatty acid.
Thus, the compounds that are not fatty acids are A, D, and E.
