Study Notes on Isoenzymes (With Diagram)

The below mentioned article provides study notes on Isoenzymes. Isoenzymes or isozymes are proteins which have different molecular and physicochemical properties, but have identical catalytic activity. They generally occur in branched metabolic pathways in which several end-products are synthesized from a common precursor molecule. A hypothetical branched pathway in which three different end-products, X, Y and Z, are synthesized from [...]

Biosynthesis of Various Types of Nucleotides

In this article we will discuss about the biosynthesis of various types of nucleotides:- 1. Pyrimidine Nucleotides 2. Purine Nucleotides. 1. Pyrimidine Nucleotides: Biosynthesis of pyrimidine nucleotides begins with condensation of a carbamyl residue of carbamyl phosphate with aspartic acid to produce carbamyl aspartate and inorganic phosphate. Carbamyl aspartate is dehydrated and cyclized to dihydro-orotic acid which is next dehydrogenated [...]

Molecular Structure of Lipids (With Diagram)

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 [...]
