Study Notes
Amino Acids and Proteins
- An amino acid consists of a central carbon atom bonded to a carboxyl group, an amino group, a hydrogen atom, and a side chain (R group).
- There are 20 standard amino acids that serve as the building blocks of proteins.
- Proteins consist of one or more chains of amino acids.
- The 20 standard amino acids differ from each other in their unique side chains (R groups).
- The side chains in amino acids play a crucial role in determining the overall properties and function of a protein, such as enzyme activity, protein-protein interactions, and antigenicity.
- The structure of an amino acid can be described as a central carbon atom bonded to a carboxyl group, an amino group, a hydrogen atom, and a side chain (R group).
- Proteins are composed of amino acids, and the sequence of amino acids determines the unique properties and function of a protein.
- There are 20 different types of standard amino acids used to make human proteins.
- The 20 standard amino acids are distinguished from each other by their unique side chains (R groups).
- The side chains in amino acids are responsible for determining the overall properties and function of a protein.
