QUESTION
Most neutral fat in ruminant animal is synthesized from?
OPTIONS
(A) Acetate
(B) Glucose
(C) Mannose
(D) Propionate
ANSWER
(A) Acetate
EXPLANATION
Acetate is the correct option because acetate is the major absorbed VFA in ruminants and is an important precursor for de novo fatty-acid synthesis, particularly in adipose tissue and the mammary gland. Glucose is relatively less available as a direct lipogenic precursor in ruminants because much dietary carbohydrate is fermented in the rumen, while mannose and propionate are not the principal precursors of neutral fat.
