Willmott 2 amino acid structure

Question 1

PEPTIDE BOND is also known as

Answer 1

AMIDE BOND

O=C-N-H

Question 2

PLANAR:

Answer 2

due to partial double bond character, limits rotataion angle between amino.as = energetically unfavourable

Question 3

Amide plane:

Answer 3

no rotation around N-C

Question 4

Alpha Carbon:

Answer 4

carbon side chains bond to Side grp

Question 5

EXAMPLE OF PHOSPHORYLATION
