Study Notes
Amino Acid Structure
- In an L-amino acid, the hydrogen atom is not attached to the α-C.
- The side chain (R group) is attached to the α-C in an L-amino acid.
Protein Formation
- Peptide bonds form a protein through a condensation reaction.
Amino Acid Functional Groups
- Proline is the amino acid that contains an imino group (NH).
Classification of Amino Acids
- Amino acids are classified based on the number of carbon atoms they contain: alpha (α), beta (β), gamma (γ), and delta (δ).
Nutritional Value of Amino Acids
- The nutritional value of an amino acid is determined by its ability to be synthesized by the human body or obtained from the diet.
