Enzyme Commission Number

  What is Enzyme Commission Number? The Enzyme commission number or “EC number” is a numerical classification scheme for enzymes based on the chemical reactions they catalyze. This system of nomenclature of enzymes was set up by International Union of Biochemistry (IUB) in consultation with the International Union of Pure and Applied Chemistry (IUPAC) in 1955. The detailed chart of Enzyme Commission Number is given below:- Class-1:- Oxidoreductase 1.1.–.– Acting on the CH–OH group of donors 1.   1. 1.– With NAD or NADP as acceptor 1. 1. 2.– With a cytochrome as acceptor 1. 1. 3.– With oxygen as acceptor 1. 1. 4.– With a disulfide as acceptor 1. 1. 5.– With a quinone or similar compound as acceptor 1. 1.99. – With other acceptors 1.2. –.– Acting on the aldehyde or oxo group of donors 1.   2. 1.– With NAD or NADP as acceptor 1. 2. 2.– With a cytochrome as acceptor 1. 2. 3.– With oxygen as acceptor 1. 2. 4.– With a disulfide as acceptor 1. ...

Remarkable properties of Enzymes as catalysts

-
Image
Enzymes display a number of remarkable properties when compared with other types of catalysts. The three most important are their high catalytic power, their specificity, and the extent to which their catalytic activity can be regulated by a variety of naturally occurring. Those three properties are as follows:- 1. Catalytic power:-                        Enzymes may increase the rate of reaction by as much as  10 17 folds. There are not many examples where a direct comparison can be made between the rates of an enzyme-catalysed reaction and the reaction occurring under similar conditions of temperature, pH, etc., but in the absence of enzyme. This is because in the absence of enzyme the rates may be too low to be measured easily. In other instances, where enzymatic and non-enzymatic catalysts are compared, the former catalyse much higher rates and in some cases do so at significantly lower temperature. The optim...

Introduction to Enzymes.

  What are enzymes? Enzymes are catalysts that is they speed up the rates of reactions without undergoing any sort of permanent change. They are also called as " Biocatalysts ". The word " enzyme"  is derived from the Greek language and its literal meaning is " in yeast " and it was first used by scientist Khune in 1878. The term enzyme was thus intended to emphasize that catalytic activity was " in yeast" that is a manifestation of an extraction or a secretion rather than of the whole organism. History of study on Enzymes. 1. In 1897, scientist Buchner did an experiment to show that activity of an enzyme could be expressed without the need of intact cellular structure by using filtrates of yeast extracts to catalyse the fermentation process. 2. In 1894, Emil Fischer  performed some classical studies on carbohydrate metabolizing enzymes in which he demonstrated the specificity shown by an enzyme for a substrate. On the basis of his experiments h...

Convalescent Plasma Therapy(CPT)

-
Image
History of Convalescent Plasma Therapy (CPT)?                     The concept if this therapy dates back more than a century, when similar treatments were used during Plague, Spanish flu, Diphtheria outbreak and recently in Ebola virus too. What is CPT?                       The idea behind this theory is that immunity can be transferred from a healthy person to a sick person via “Convalescent Plasma”. Convalescent plasma refers to plasma of a recovered COVID-19 patient. In simple words antibodies from a recovered COVID-19 patient are obtained and are provided to a sick person. How CPT works?                        In this therapy, blood from a recovered COVID-19 patient is taken and the serum is separated and screened for virus neutralizing antibodies or antibodies against Corona virus. When any di...
