(2R,3R)-2-Amino-3-methylpentanoic acid Usage And Synthesis

Chemical Properties

white to very slightly yellow powder

Uses

May contain up to 10% allo-isomer.

Uses

D-Isoleucine is not biosynthesized in the human body and is therefore categorized as an essential amino acid that must be obtained through diet. It is also an important building block that is used in the formation of hemoglobin in humans.

Definition

ChEBI: The D-enantiomer of isoleucine.
