In this article we will discuss about the primary structure of peptides and proteins. Peptides and proteins consist of chains of amino acids linked by peptide bonds. We observe a structure analogy with the biuret molecule, formed by the condensation of 2 urea molecules (as indicated by its name) with elimination of one molecule of NH3(H2N—CO — NH-CO —NH2) and [...]
In this article we will discuss about:- 1. Denaturation of Proteins 2. Important Properties of Proteins 3. Classification. Denaturation of Proteins: The three-dimensional conformation (the primary, secondary, tertiary and even in some cases, quaternary structure) is characteristic of a native protein. This conformation can be upset and disorganized, without breakage of any peptide linkage, only by the rupture of linkages [...]
In this article we will discuss about the various structures of proteins. This will also help you to draw the structure and diagram of proteins. Proteins consist of long polypeptide chains and we know how to determine the sequence of the amino acids of these chains. This constitutes the primary structure of proteins. But in reality, each protein has a [...]
