The following points highlight the four main structures of Protein Organisation. The structures are: 1. Primary Structure 2. Secondary Structure 3. Tertiary Structure 4. Quarternary Structure. 1. Primary Structure: It is the description of basic structure of a protein. This includes number of polypeptides, number and sequence of amino acids in each polypeptide. The latter is determined genetically (by DNA) [...]

The below mentioned article provides a quick note on Denaturation of Proteins. Denaturation of Proteins: Denaturation may be defined as the disruption of the secondary, tertiary and quarternary structure of the native protein resulting in the alterations of the physical, chemical and biological characteristics of the protein by a variety of agents. The native proteins are said to be the [...]
