In this article we will discuss about metabolism of fatty acids. Most of the naturally occurring neutral fats and oils are esters of glycerol and long-chain fatty acids, the most common among them being palmitic acid (C16-saturated fatty acid) and stearic acid (Cig-saturated fatty acid). The degradation of fats begin with hydrolytic cleavage of fatty acids by the enzymes, lipases. [...]
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 [...]
