Isoenzyme, Isoenzym: physically distinguishable forms of enzymes

Enzymes play an important role in cellular processes, speeding up chemical reactions and providing vital body functions. However, along with ordinary enzymes, there are different forms of them, called isoenzymes or isoenzymes. In this article we will look at what isoenzymes and isoenzymes are, how they are formed and what their role is in the body.

Isoenzymes are physically distinguishable forms of an enzyme that can be distinguished by their electrophoretic, chemical or immunological properties. Isoenzymes differ from ordinary enzymes by small changes in the structure of the protein molecule, which can occur due to various reasons, such as genetic mutations, changes in the environment, or different stages of development of the organism.

Isoenzymes catalyze the same chemical reactions as their associated enzymes, but they may have different physical and immunological properties. For example, isoenzymes may differ in molecular weight, isoelectric point, rate of migration in a gel, or ability to bind antibodies. These properties can be used to separate isoenzymes and isoenzymes when studying them.

The most well-known isozymes are dehydrogenases, oxidases, transaminases, phosphatases and proteolytic enzymes. Dehydrogenases play an important role in the metabolism of carbohydrates, fats and amino acids, oxidases are involved in oxygen and energy metabolism, transaminases transfer amino groups from amino acids to keto acids, phosphatases are involved in phosphorus metabolism, and proteolytic enzymes break down proteins into individual amino acids.

Isoenzymes can also be formed by the expression of different genes that encode the same enzyme, but in different tissues or stages of development of the organism. For example, creatine kinase isoenzymes are found in muscle and brain tissue, and lactate dehydrogenase isoenzymes can be found in blood, muscle, and liver.

Isoenzymes and isoenzymes can play an important role in disease diagnosis and treatment monitoring. For example, changes in the level of enzyme isoenzymes in the blood or other biological fluids may indicate the presence of pathological processes in the body. Isoenzymes can also be used to identify different types of organisms, for example, in medicine or in environmental studies.

In conclusion, isoenzymes and isoenzymes are physically distinguishable forms of enzymes that can be distinguished by various properties such as molecular weight, isoelectric point, and ability to bind to antibodies. Isoenzymes catalyze the same reactions as their related enzymes, but may have slight physical and immunological differences. The most well-known isozymes are dehydrogenases, oxidases, transaminases, phosphatases and proteolytic enzymes. Isoenzymes can be formed by the expression of different genes that encode the same enzyme, but in different tissues or stages of development of the organism. Isoenzymes and isoenzymes can play an important role in disease diagnosis and treatment monitoring, as well as in the identification of different species of organisms.

Isoenzyme, Isoenzyme - a physically distinguishable form of an enzyme. Isoenzymes catalyze the same reactions as their related enzymes, but have slight physical and immunological differences from them. Currently known isoenzymes are dehydrogenase, oxidase, transaminase, phosphatase, as well as proteolytic enzymes.

Isoenzyme, Isoenzyme - enzymes that differ in physical and immunological properties, but catalyze the same reactions as the enzymes associated with them. Isoenzymes are usually formed from different isomers of the enzyme, which have different amino acid sequences or configurations.

Isoenzymes were first discovered in the 1950s when researchers noticed that different tissues had different forms of the same enzyme. For example, dehydrogenase isoenzymes may vary depending on the tissue in which they are found, as can isoenzymes of other classes of enzymes.

Isoenzymes can be useful for identifying tissues and organs, as well as for diagnosing various diseases. For example, crushing the myocardium can result in the release of isoenzymes that are normally only present in the heart.

One of the most well-known groups of isoenzymes are alcohol dehydrogenase isoenzymes, which catalyze the oxidation of ethyl alcohol. There are several isoforms of this enzyme in humans, which may differ depending on gender, ethnicity, and other factors.

Isoenzymes can also be used to study the evolution and phylogeny of organisms. For example, studying isoenzymes in different species can help determine how closely related the species are to each other.

In general, isoenzymes are useful tools for identifying various physiological processes and diseases, and for studying the evolution and phylogeny of organisms. They continue to attract the attention of researchers who seek to understand deeper aspects of the biology and chemistry of living organisms.
