QUESTION

Corn protein is low in which one of the following amino acids?

OPTIONS

(A) Lysine
(B) Leucine
(C) Arginine
(D) Glutamic acid

ANSWER

(A) Lysine

EXPLANATION

Maize protein is deficient in lysine and is therefore considered a cereal protein with an amino-acid limitation in lysine. Leucine and glutamic acid are abundant in maize protein, and arginine is not the principal limiting amino acid.
