multiple choice
leucine
tryptophan
phenylalanine

Explanation:

Tryptophan is an amino acid that can be converted into niacin (vitamin B3) in the body. Eggs and milk, while low in niacin, contain tryptophan which helps support the body's niacin status through this conversion process. Leucine, phenylalanine, and threonine do not have this conversion pathway to niacin.

Answer:

tryptophan
