(2S, 4'R, 8'R)-α-Tocopherol Chemical Properties,Uses,Production

Uses

(2S, 4’R, 8’R)-α-Tocopherol is one of the 8 stereoisomers contained in the racemic mixture of synthetic α-Tocopherol, a vitamin E substitute. Being of the (2S) orientation it is generally less active than it’s (2R) counterpart, however this biodiscrimination is suggested to occur in the liver as it does not occur in the small intestine.

Definition

ChEBI: (S,R,R)-alpha-tocopherol is the (S,R,R)-stereoisomer of alpha-tocopherol. It is an enantiomer of a (R,S,S)-alpha-tocopherol.
