Study Notes
Amino Acid Classification
- Aliphatic amino acids include glycine (smallest), alanine, valine, leucine, and isoleucine.
- Some have branched chains.
- Others have side chains with hydroxyl (-OH) groups (e.g., serine, threonine).
- Some have sulfur atoms in their side chains (e.g., cysteine, methionine).
- Some have acidic side chains (e.g., aspartate, glutamate).
- Some have amide side chains (e.g., asparagine, glutamine).
- Some have basic side chains (e.g., arginine, lysine).
Cyclic Amino Acids
- Aromatic ring structures are found in phenylalanine, tyrosine, and tryptophan.
- Heterocyclic structures include histidine (a basic amino acid) and proline (an imino acid).
