RRR-α-Tocopherol Is the Predominant Stereoisomer of α-Tocopherol in Human Milk

摘要

BackgroundThe naturally occurring α-tocopherol (α-T) stereoisomer, RRR-α-tocopherol (RRR-α-T), is known to be more bioactive than all-rac-α-tocopherol (all-rac-α-T), a synthetic racemic mixture of 8 stereoisomers. There is widespread use of all-rac-α-T in maternal supplements.
