Biomolecules Fats And Lipids Question 27

Question: An example for a saturated fatty acid, present in nature is [KCET 2005]

Options:

A) Oleic acid

B) linoleic acid

C) Linolenic acid

D) Palmitic acid

Answer:

Correct Answer: D

Solution:

Oleic acid - $ C_{17}H_{33}COOH $ , linoleic acid- $ C_{17}H_{31}COOH $ , linolenic acid - $ C_{17}H_{29}COOH $ , palmitic acid - $ C_{15}H_{31}COOH $ . Saturated monocarboxylic acids form a homologous series which has a general formula $ C_{n}{H_{2n+1}}COOH $ or $ C_{n}H_{2n}O_2 $ . Only palmitic acid follows this.
