Protein structure and folding

Protein structure and folding

1. Proteins

   • Can make up channels
   • Be a part of structure
     • Chaperonins
       • Help to fold other proteins
   • Serve as enzymes
   • Be involvent with protecting the body
   • Amino acids make proteins
     • Amino group
     • Carboxyl group
     • Side chain
       • Ionic bonds
       • Hydrogen bonds
       • Hydrophilic interactions
       • Hydrophobic interactios
       • Disulfide bridges
       • Van Der Waals interactions
   • Need optimal environment
     • Temperature
     • Ph range

2. Protein shape

   • Protein folding
     • Primary structure
       • Polypeptide
         • Amino acid sequence
         • Peptide bonds
     • Secondary structure
       • aa Sequence folding
         • Alpha helix
         • Beta pleated sheet
         • Hydrogen bonds
     • Tertiary structure
       • 3D shaped
         • Hydrophilic amino acids
           • Outside
         • Hidrophobic amino acids
           • Inside
     • Quaternary structure
       • More than 1 polypeptide chain
         • Subionics
           • Hydrogen bonds
           • Disulfide bonds
