In this article we will discuss about the molecular structure of nucleic acid with the help of diagrams. Nucleic acids constitute another important group of biological macromolecules present in all types of organisms where they function mainly as store-house of genetic information and as information- transfer molecules. Two types of nucleic acids: i. Ribonucleic acid (RNA) and ii. Deoxyribonucleic acid [...]
The following points highlight the top three pathways of glucose dissimilation in organisms. The pathways are: 1. Embden-Meyerhof Pathway or Glycolysis 2. Pentose Phosphate Cycle (PPC) 3. Entner-Doudoroff Pathway (EDP). Glucose Dissimilation: Pathway # 1. Embden-Meyerhof Pathway or Glycolysis: This catabolic pathway leads to splitting of glucose to two molecules of pyruvic acid i.e. a six- carbon compound is broken [...]
The below mentioned article provides notes on hydrocarbon metabolism in organisms. Hydrocarbons are organic compounds containing carbon and hydrogen. The simplest hydrocarbon is methane (CH4). A host of bacteria can also use other hydrocarbons like alkanes, alkenes, cyclic and aromatic compounds. Alkanes are linear saturated hydrocarbons having the general formula CH3-(CH2)n-CH3, while alkenes are unsaturated linear molecules. Some examples of [...]
