structures of proteins v2
primary structure of proteins
amino acids can be arranged in many diffrent combinations.
Insulin one of the simplest proteins contains 51 amino acids
different bonds
disulphide
disulphide bonds occur when two sulphurs from two amino acids join together from either a single polypeptide chain or two different polypeptide chain
The amino acid cysteine contains sulfure
insulin contains disulfie bonds
hydrogen bonds
Hydrogen bonds occur when a hydrogen from the N-H group of one amino acid and a oxygen from the C=0 group of another amino acid join together from either a single polypeptide chain or two different polypeptide chains
collagen contains hydrogen bonds
Teritary stucture
involves the folding of the secondary scturcutre of proteins into. three-dimensional shaped
further cross linking between amino acids forms definite shapes which may be fibrous or globular .
secondary structure -folding
There are two main types of cross link: disulphide bonds and hydrogen bonds.
poly peptide chains either fold in on themselves or cross link with another polypeptide chain.This causes the chains to form a spiral shape.
secondary involves folding of the primary stucure of proteins into definite shapes
different structure
fibrous
polypeptide chains are arranged in straight spiral or zigzag shapes
globular
polypeptide chains are arranged in a globular shape
