Complete data

Leucine is one of the 20 common amino acids coded for by DNA. It is isomeric with isoleucine. Nutritionally, in humans, leucine is an essential amino acid.

Leucine is the most common amino acid found in proteins, and is essential for optimal growth during infancy and childhood. In adults it is essential for maintaining nitrogen equilibrium. It is suspected that Leucine plays a part in maintaining muscles by equalizing the synthesis and breakdown of proteins.

The major food sources of leucine are whole grains and milk products. Eggs, pork, beef, chicken, pulses, soybeans, and leaf vegetables are good sources of leucine.
