Before telling you what are the main functions of polysaccharides in plants, I would like to mention about polysaccharides first. Polysaccharides are the carbohydrates that mean hydrates of carbon. The simplest formula for carbohydrates is Cn(H2O)n, where n can be 3 or more than 3. The simplest …
You will be surprised to know that we are carrying non-human genes in our genome. Our genome is not completely human genome. I mean to say, we, human beings have some of the non-human genes (foreign genes) initially derived from some other organism during the course …
Hormones are the first messengers that trigger the various biological and physiological processes inside the body. Among the various types of hormones, steroid hormones are important because of their hydrophobic nature. The main precursor of the steroid hormones is the cholesterol that is why they are …

A short introduction about HMG-CoA reductase HMG-CoA reductase or 3-hydroxy-3-methylglutaryl coenzyme-A reductase is an endoplasmic reticulum membrane-bound enzyme. It catalyzes the conversion of HMG-CoA to mevalonate. This step, formation of the mevalonate, is the rate-limiting step of the cholesterol biosynthesis as well as the synthesis of …

Tryptophan aminotransferase is an enzyme that catalyzes the transamination of L-tryptophan. It requires pyridoxal phosphate as a cofactor and an amino group acceptor alpha-ketoglutarate. Tryptophan aminotransferase catalyzes the first step of indole-3-acetic acid (an auxin) biosynthesis and its product is indole-3-pyruvate. Indole-3-acetic acid is a plant growth …

Indole-3-pyruvate decarboxylase is an important enzyme involved in the biosynthesis of indole-3-acetic acid, a plant growth hormone. The indole-3-acetic acid biosynthetic pathway involving indole-3-pyruvate decarboxylase is called an indole-3-pyruvate pathway and indole-3-pyruvate is the key intermediate of this pathway. The first enzyme of this pathway is …
