Humans use D sugars and L amino acids. L sugars and D amino acids are toxic. That optically active carbon is important. Racemization is the characteristic of having a mix of D and L forms. In the case of vitamin E, only the D isomer is biologically active. Cheap drugstore vitamin E is often half inactive racemized junk. Review your biochemistry.
“Review your biochemistry.”
He’s too busy insisting that he’s intellectually superior.
But before you go back to your sophomore chemistry books (if you ever studied from one) go back to first grade and study your Dick and Jane, because your reading comprehension needs work.
Isomers aren't structurally the same molecule, which this poster claimed. Derp.
In particular, Enantiomers aren't structurally the same molecule; they're mirror images of each other. Duh?!
READ what the poster posted, and READ what I actually responded to. Then you can send me an apology via private FReepmail, so you don't have to publicly humiliate yourself.
