Digestion of proteins

• What breaks down proteins?

  Proteases
• What does endopeptidases do?

  Hydrolyse peptide bonds within a large protein to create smaller peptide chains

  Create more terminal ends for exopeptidase
• What do exopeptidases do?

  Hydrolyse terminal peptide bonds to remove individual amino acids and create smaller peptide chains
• What do dipeptidases do?

  Work on dipeptides and hydrolyse the bond holding them together making two singles amino acids

  Transporting them through membrane to epithelial cell
• How are amino acids absorbed?

  Active co transport
