Molecular formula :C6H13NO2
Molecular weight :131.17Leucine, also known as leucine and chemically known as α-monoamino-isocaproic acid, was first isolated from cheese by Proust in 1819. Later, Braconnot crystallized it from the acid hydrolysate of muscle and wool and named it leucine. L-leucine is one of the 18 common amino acids and one of the eight essential amino acids in the human body.

Function and use

Leucine can be used as a nutrient supplement and flavor enhancer. The role of leucine includes working with isoleucine and valine to repair muscles, which help promote muscle recovery after training and are especially suitable for bodybuilders.
Good food sources of leucine include brown rice, beans, meat, nuts, soy flour, and whole grains. Since it is an essential amino acid, this means that the body cannot produce it on its own and can only get it through diet
