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 [...]
As indicated by their name, these are coloured proteins, their prosthetic group often contains a metal element (Fe, Cu, Mg). These compounds are generally classified on the basis of their prosthetic group having, or not having, the tetrapyrrol structure called porphyrin and according to their respiratory or non-respiratory physiological role. 1. Porphyrin Chromoproteins: A. Respiratory Pigments: They all contain iron. [...]
In this article we will discuss about:- 1. Classification of Peptides 2. Nomenclature of Peptides 3. Preparation and Purification 4. Study. Classification of Peptides: As already mentioned oligopeptides and polypeptides are distinguished depending on whether the peptide is formed by the union of less than 4 or at least 4 amino acid. Natural peptides consist of different amino acids; but [...]
