Protein Structure and Folding

Protein Structure and Folding

1. PROTEIN STRUCTURES

   • Primary Structure
     • Its build of Amino Acids. It has Peptide bonds. Amino acids form a Polypeptide chain.
   • Secondary Structure
     • The structure can fold in different ways: Alpha Helix and Beta Plated Sheet. This shapes are thanks to Hydrogen bonds.
   • Tertiary Structure
     • This structure is thanks to the R groups. The R group can vary between amino acids. This groups can make amino acids hydrophobic or hydrophilic, this causes the 3D folding
   • Quaternary Structure
     • Its made of more than 1 polypeptide chain. They interact by hydrogen bonds or disulfide bonds.
   • They are the different structres that a protein can have depending of its necesities

2. FOLDING

   • Is the way like proteins fold depending of their characteristics and structures
   • Chaperonins
     • They have a barrel shape
     • It has an ideal environment for the protein folding
     • Protein folding its necessary for a well functioning of each protein
