Formation of DIPEPTIDES Formation of POLYPEPTIDE
Note: PROTEINS
2 amino acids joined (hence the di) • Peptide molecules made by joining alpha
1 peptide bond! acids in condensation reaction peptide b
• Combining MORE THAN 2 A.A.’s POLYPE
(which can then lead to protein formatio
2 A.A.’s join in CONDENSATION
reaction (so –H2O) DIPEPTIDE • If polypeptide made from 50-2000 A.A.’s
protein chain
Peptide link/bond
A.A. molecules can be same/ different:
• 2 of the same A.A. = 1 dipeptide possible
• 2 different A.A. = 2 dipeptides possible
