Document Summary

All alpha amine and central alpha carbon, and alpha carboxy. (cid:1) Off central alpha carbon is a hydrogen and then differentiated by side chains (cid:1) Stereochem comes because alpha carbon is sp3, 4 different substituents (cid:1) Relative postioning of them defines polymers shapes that come as aas bind (cid:1) (cid:1) One amino acid with no stereochem; glycine as it has 2 hs. Wedge comes out and dash goes away from us; can represent with fischer projection (cid:1) Alpha carbon central and horizontal goes out of page and vertical is in page (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) D and l forms; r and s were used in orgo but here we use d and l. Corn coo then r group and then n. Corn is for aas; do not apply for anything else. Orient h towards you, spell corn, find direction. Clockwise l and countercloxkwise is d (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) it is d.
