Study Notes
Amino Acid Structure and Properties
- Amino acids possess both amino and carboxyl functional groups.
- There are 20 amino acids commonly found as constituents of mammalian proteins.
Amino Group Characteristics
- Proline has a secondary amino group.
- The amino group is basic in nature.
Carboxyl Group Characteristics
- At physiologic pH (pH= 7.4), the carboxyl group has a negative charge.
Classification of Amino Acids
- Amino acids are classified according to their properties, including the properties of their side chains.
- Hydrophobicity and charge of the side chains play a role in classifying amino acids.
pH and Amino Acid Form
- At physiologic pH (pH= 7.4), amino acids mostly exist in their zwitterionic form.
