Worksheet time: 5mins
The monomer of proteins are
GLUCOSE
AMINO ACID
FATTY ACID
PEPTIDES
The unique characteristic of each amino acid is determined by
Its R group.
Its amino group
The type of peptide bond.
Its position on the polypeptide chain
A polypeptide chain usually begins with a free amino acid group (N-terminal) and ends with a free carboxyl group(C-terminal). In theory, how many peptide bonds that can be formed from the condensation of 20 amino acids?
