Question

Which of the following statements are true regarding fatty acids?
I. Fatty acids with fewer than 14 carbons are the most common.
II. Synthesis of fatty acids occurs in 2 carbon units.
III. Fatty acids with conjugated double bonds are the most common type of fatty acid.
IV. In higher plants and animals, C16 and C18 species predominate.

Answer 1

Answer:

Option (I) and (IV).

Explanation:

Fatty acids may be defined as the carboxylic acid that contains the long aliphatic chain. Fats are generally of two types - saturated fatty acid and  unsaturated fatty acid.

The fatty acids are generally synthesized in the two carbon units. This helps in the proper synthesis of fat. The fatty acids that are most common in plants and animals are palmittic acid or the fats that contain  C16 and C18 species predominate.

Thus, the correct answer is option (I) and (IV).
