Before telling you what are the main functions of polysaccharides in plants, I would like to mention polysaccharides first. Polysaccharides are 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 carbohydrates are …
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 cholesterol which is why they are hydrophobic …

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, the formation of the mevalonate, is the rate-limiting step of 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 …

Tryptophan decarboxylase is an enzyme that catalyzes the conversion of tryptophan to tryptamine. Tryptamine is a first-reaction intermediate of indole-3-acetic acid (a type of auxin) biosynthesis. Therefore, to study the tryptamine pathway of indole-3-acetic acid biosynthesis, it is necessary to check the activity of the enzymes …
