Introduction Normally, blood flows through the blood vessels in fluid form. However, the blood lost through a ruptured blood vessel gradually becomes a jelly-like blob, hardening into a solid mass within a few minutes. In physiology, this phenomenon is called blood coagulation. In short, coagulation means the clotting of blood. Any abnormalities in the body’s […]

Enzymes are proteins that help speed up the metabolic activities in the body or chemical reactions in the body. The human body undergoes a lot of chemical reactions every day that are fastened by using enzymes. These enzymes are obtained from proteins formed by linking amino acids in different combinations in the form of long-chain

Introduction In science, in the most established and broadest sense, a microbe is any organic waste that can create illness. A microbe may likewise be alluded to as an irresistible specialist or just a microorganism. The term microbe came into utilization in the 1880s. Typically, the term portrays an irresistible microorganism or specialist, like an

Charles Freidel and James Crafts invented the Friedel–Crafts reactions in 1877 to attach substituents to aromatic rings. The alkylation and acylation responses are the two most common Friedel–Crafts responses. Friedel–Crafts Alkylation refers to the substitution of an alkyl group for an aromatic proton. With the assistance of a carbocation, an electrophilic attack on the aromatic

Enzymes are proteins that help speed up metabolic activities or chemical reactions in the body. The human body undergoes many chemical reactions every day that are fastened by enzymes. These enzymes are obtained from proteins formed by linking amino acids in different combinations in the form of long-chain compounds. All living organisms have enzymes, and

Enzymes are biological molecules that act as catalysts that speed up the processes. They are protein sources that are formed by chains of amino acids in various combinations. Enzymes are highly specific in reactivity. There are thousands of enzymes in the human body that will catalyse various metabolic reactions occurring in the body.  What are

Introduction: In the era of covid nowadays, we are very much familiar with the word Antimicrobials, which is very common and almost everyone could understand. But in layman’s terms, an antimicrobial is an agent which can be defined as a natural or synthetic substance that is responsible for killing or inhibiting the growth of microorganisms

Enzymes are considered biological molecules that act as catalysts to speed up various processes. They are protein sources formed by chains of amino acids in various combinations. Enzymes are highly specific in reactivity. There are many enzymes in the human body that catalyse various metabolic reactions occurring inside the body. Enzymes work in the mild

The hepatic portal system is the vein that connects the digestive tract and the spleen to the liver (where raw nutrients in blood are processed before the blood returns to the heart). Essentially, it drains the structures fed by the celiac (with the exception of the gonads), anterior mesenteric, gastro splenic, and posterior mesenteric arteries.
