Study Notes

Amino Acids

  • There are 20 standard amino acids that occur naturally in proteins
  • Amino acids are the building blocks of proteins
  • Amino acid residues play a crucial role in determining the properties and functions of proteins

Nomenclature of Amino Acids

  • The IUPAC-IUBMB Joint Commission on Biochemical Nomenclature is responsible for formally naming amino acids
  • The basis for systematically naming amino acids is the α-carbon atom
  • Amino acids are named based on the composition of their side chain

Classification of Amino Acids

  • Amino acids are classified based on polarity, ionization, and side chain group type
  • This classification is important because it helps to understand the properties and functions of proteins
  • The main reason for this classification is to understand the interactions between amino acids and their environments
