  • Contain...
    • A central carbon atom
    • An amine group (NH2) 
    • A carboxyl group (COOH)
    • A side chain or R-group 
      • The R-group is different in each amino acid 
        • there are 20
    • The simplest amino acid is glycine 
      • The R-group is a hydrogen atom
        • The R-group gives each amino acid unique properties 
    • Some amino acids are called essential amino acids
      • These 10 amino acids are not synthesised by the human body,
        • must be obtained from the diet
    • Arg, His, Ile, Leu, Lys, Met, Phe, Thr, Trp, and Val, R-groups
      • may be positively charged
        • negatively charged
          • hydrophilic
            • or hydrophobic
