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.

Question

Quizplus · Accepted Answer

Fatty acid synthesis occurs in 2 carbon units, typically involving the addition of acetyl-CoA units. In higher plants and animals, fatty acids with chain lengths of 16 (palmitic acid) and 18 (stearic acid) carbons are predominant, not those with fewer than 14 carbons or those with conjugated double bonds.
