proteins are made up of smaller amino acid subunits
20 different amino acids (almost all a-amino acids) |
|
|
amphoteric substance
|
contains both acidic and basic group; peptide bonds can form between

|
|
dipeptide
|
condensation product from amino acids combining
amino group at one end, carboxyl group at the other (may continue to form chains = polypeptide) |
