Resumo de Recurso
Protein Structure
Two groups
Globular Proteins
Take part in reactions
Enzymes
Roughly spherical
Fibrous Proteins
Have structural roles
Such as giving strength or elasticity
E.g. Collagen and keratin
Made up of amino acids
Join together in a condensation reaction
Chain of amino acids is called a polypeptide
Proteins consist of one or more polypeptide
2 amino acids form a dipeptide
20 different amino acids
Join together in any order
Infinite number of different protein molecules
Contain carbon, hydrogen, oxygen and nitrogen. They often contain sulfur and phosphorus
Four levels
Primary Structure
The sequence of amino acids in the polypeptide
Secondary Structure
The twisting and folding of the polypeptide chain to form an alpha helix or beta pleated sheet, held together by hydrogen bonds
Tertiary Structure
The complex twisting and folding of the polypeptide chain to give a 3 dimensional shape. Held together by bonds between the R groups
Hydrogen bonds, ionic bonds, covalent bonds, disulfide bonds
Quaternary Structure
The presence of more than one polypeptide chain in a protein. The polypeptide chain are held together by bonds between R groups AND/OR the presence of non-protein prosthetic groups in the working protein
