10.1 Applications in Medicine - Recombinant Insulin Production

  • Insulin is a 51-amino acid hormone produced by β cells of Islets of Langerhans in pancreas
  • Insulin consists of two polypeptide chains: Chain A (21 amino acids) and Chain B (30 amino acids) linked by disulfide bonds
  • Normal insulin from pig and cow pancreas caused allergic reactions due to structural differences

10.1.2 Human Alpha Lactalbumin and Transgenic Animals

  • Alpha lactalbumin is a 123-amino acid protein with 4 disulfide bridges and molecular weight of 14178 Da
  • Most abundant protein in human milk (25% of total protein), synthesized by mammary glands
  • Binds calcium and zinc ions, possesses bactericidal and anti-tumor activities
3

10.1.3 Interferons - Antiviral Proteins

  • Interferons are proteinaceous, antiviral, species-specific substances produced by mammalian cells infected with viruses
