Question

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 1

The Correct Option is C

Fatty acids: These are long-chain carboxylic acids. Palmitic acid (C) and arachidonic acid (B) serve as examples.
Amino acids: Glutamic acid (A) and aspartic acid (E) are amino acids; they form the basis of proteins and are distinct from fatty acids.
Phospholipid: Lecithin (D) is a phospholipid, a key constituent of cell membranes. Although lecithin incorporates fatty acids, it is not a fatty acid itself.
Consequently, compounds A, D, and E are not fatty acids.
