Isoleucine
An essential branched-chain amino acid, like leucine and valine: the body cannot make it and obtains it from dietary protein. It was discovered in 1903 by the German chemist Felix Ehrlich. This family brings together the active ingredient, labelled standards and other impurities.
Did you know?Ehrlich found it while studying beet-sugar molasses; only in 1907 did he confirm its presence in common proteins such as fibrin, egg albumin and gluten.
