Substrate

A substrate is a specific substance or substances that are acted upon by a specific enzyme. The substrate binds to the active site of the enzyme, forming an enzyme-substrate complex. The interaction of enzyme and substrate leads to the formation of a reaction product.

For example, starch is a substrate for the salivary amylase enzyme. Amylase breaks down starch into simpler sugars. Another example is ribonuclease, which interacts with its substrate RNA and breaks it down into nucleotides.

Thus, the concept of “substrate” implies a specific substance that undergoes chemical transformations under the action of an enzyme. Identification of the substrate is necessary to understand the mechanism of action of enzymes.

A substrate is a specific substance that undergoes the catalytic action of an enzyme to become active in the metabolic chain. Depending on the type of enzyme and the function it performs, the substrate may be one or more molecules, and its structure may differ markedly from that of the enzyme. When considering the biochemical functioning of organisms, it is important to understand

Substrates and enzymes

Substrates are substances that are targets for specific enzymes in the body. These enzymes catalyze biochemical reactions by binding to substrates and converting them in specific ways. Substrates can be of various natures: they can be proteins, nucleic acids, carbohydrates or lipids.

Enzymes can be classified according to their function. There are many different types of enzymes that perform different functions in organisms. Some of the most important types of enzymes include lipases, amylases, proteases, and nucleases.
