In this article we will discuss about some chemical compounds like acid, base and buffers. Acid and Base: An acid may be defined as a substance which, when dissolved in water, produces hydrogen ions [H+] or in other words, it is the compound of electronegative element with ionisable hydrogen [H+]. Similarly a base or alkali is a substance which produces [...]
This article throws light upon the two main types of isomerism in molecules. The types are: 1. Structural Isomerism 2. Stereo Isomerism. Type # 1. Structural Isomerism: When the isomers differ only in the arrangement of atoms or groups within the molecule, without any reference to space, these are known as structural isomers and the phenomenon as structural isomerism. Thus, [...]
The following points highlight the five main classes of chemical compounds in chromatin. The classes are: 1. Nucleic acids 2. Basic proteins or histones (protamines in sperm nuclei of some fishes and birds) 3. Acidic proteins (Non-Histones) 4. Lipoproteins 5. Associated inorganic molecules. Chemical Compounds in Chromatin: Class # 1. Nucleic Acids: The nucleic acids are of two types: (i) [...]
