A catalyst — whether chemical or biological — acts by increasing the velocity of reactions. We will now examine the kinetics of enzymatic reactions. The velocity of an enzymatic reaction is generally followed up by measuring the quantity of substrate transformed per unit time; one can also record the quantity of the product (or one of the products) formed by [...]
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 [...]
