Document Summary
Office hours tues, thurs, friday 8:30 to 10am msb 5221. Proteins are molecules of action; dna molecule of information. Proteins are involved in step to make dna, to transcribe into rna, and to make proteins. Hydroxyl group is polar: know how to describe structure in terms of functional groups. All have amine group nh3 plus and carboxyl group. Backbone n, c alpha and c. R group = side chain: gives amino acid its properties. Ionic = charged either positive or negative: zwitterionic has both positive and negative charge so cancel out. but the two charges can play a role so instead of saying neutral, it s zwitterionic. Chiral can draw representations of them in mirror images: mirror images of each other cannot be superimposed. L and d: the way it looks, the pattern, l. Look down proton read out the substituents, corn spelled out. Glycine is not chiral clockwise: r group is proton, do not have four different substituents.
