General Features of Protiens

A protein is a unique three dimensional biologic polymer constructed from 20 different monomers called aminic concourse pungent. Some of aminic acids ar glycine, alanine, valine, leucine etcetera There are three morphologic levels in the strain of a protein called primary, secondary, and tertiary complex body part. Primary structure is the unique genetically coded sequence of amino acids within a protein. Amino acids are bonded by peptide bond which links the amino concourse of wizard amino acid with the carboxyl group of another, yielding a polymer of amino acid called polypeptide. The polypeptide varies greatly in length from a hardly a(prenominal) to thousand amino acid and has a amino group at one expiry and carboxyl group at the other end. Sanger, 1940, first sequenced insulins amino acid first. veritable(a) a slight deviation from the sequence of amino acids raft severely affect a proteins function by fix the proteins conformation like a single mutation of amino acid in hemoglobin case reap hook kiosk anemia, a blood disorder that may be transferred from genesis to generation. Secondary structure involves the coiling of folding of the polypeptide backbone. An alpha helix is a delicate coil produced by henry bonding amidst every fourth peptide bond in the polypeptide chain.

An object lesson of a alpha helix containing protein is alpha keratin, the structural protein of the tomentum which has alpha helix through out its length. A pleated constant gear is excessively held by repeated hydrogen bonds on the proteins backbone. An example of pleated aeroplane is the structural protein of the silk. In an globular protein pleated sh! eet make up the core of the protein, and alpha helix forms the few stretches which is separated by the non helical region. Tertiary structure of a protein is formed by the interactions surrounded by the various incline chains of the constituent amino acids. Different...
