In this article we will discuss about the classification of enzymes. Some enzymes are often designated by common names based on usage (pepsin, trypsin, chymotrypsin, papain etc); but these names contain no information on the substrate and the reaction catalyzed. In certain cases, enzymes catalyzing hydrolysis reactions are designated by the name of the substrate followed by the suffix "ase" [...]
This article throws light upon the four main types of receptors. The types are: 1. Receptors for Fast Neurotransmitters 2. Receptor for many Hormones and Slow Transmitters 3. Receptors for Insulin and Various Growth-Factors 4. Steroid Receptors. Type # 1. Receptors for Fast Neurotransmitters: These are coupled directly to an ion- channel. These receptors are involved mainly in fast synaptic [...]
In this article we will discuss about the classification of lipids. Contrary to carbohydrates which constitute a family of relatively homogenous compounds, lipids form a very heterogenous class of compounds of widely differing structures and grouped according to their insolubility in water and solubility in organic solvents (ether, acetone, chloroform-alcohol mixtures, etc.). These solubility criteria are not absolute. Lipids were [...]
