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 [...]
In this article we will discuss about the molecular structure of lipids. Lipids are another group of important biological molecules present in all cellular organisms and some viruses. Unlike the other groups of biological molecules, lipids are highly heterogenous in chemical structure. But all of them possess a common physical property which is that they are all non-polar compounds, insoluble [...]
In this article we will discuss about the biosynthesis of murein. A characteristic polymer that forms the backbone of all eubacterial cell wall is peptidoglycan or murein. Murein essentially consists of parallelly running polysaccharide chains, the repeating unit of which is a disaccharide of N-acetyl-glucosamine (NAG) and N-acetyl muramic acid (NAM) having a tetra-peptide bonded to its lactyl group. The [...]
