Peroxisome (Peroxisote)

Peroxisomes (or Peroxisomes) are an important part of the cellular structure that plays a role in the regulation of many cellular processes. Despite the fact that peroxisomes were discovered back in the 1950s, they have not yet received the same attention as many other organelles.

Peroxisomes are small membrane-bound organelles with a diameter of 0.1 to 1 μm. They are found in almost all cells of living organisms, including plants and animals.

One of the main functions of peroxisomes is the decomposition of hydrogen peroxide (H2O2), which is formed as a result of metabolic processes in the cell. Peroxisomes contain enzymes such as catalase and peroxidase, which are involved in the synthesis and breakdown of hydrogen peroxide.

Catalase, which is one of the most abundant enzymes in peroxisomes, is the main catalyst for the breakdown of hydrogen peroxide into water and oxygen. Thus, peroxisomes are key organelles for maintaining the redox balance in the cell.

In addition, peroxisomes are involved in other important processes such as beta-oxidation of fatty acids and cholesterol synthesis. They also play a role in breaking down amino acids that cannot be used by the cell.

Peroxisomes are important for human health. For example, some genetic diseases, such as Addison's disease, are associated with defects in the formation and function of peroxisomes. Peroxisomes may also be associated with the development of many serious diseases, such as cancer and Alzheimer's disease.

In conclusion, peroxisomes are important organelles that play key roles in many cellular processes. They ensure the maintenance of redox balance and are involved in metabolic processes such as beta-oxidation of fatty acids and cholesterol synthesis. Understanding and studying peroxisomes can help develop new treatments for many diseases.

Peroxisomes are small intracellular organelles that play an important role in cellular metabolism. They are similar to lysosomes, but contain enzymes involved in the breakdown and synthesis of hydrogen peroxide.

Peroxisomes have a diameter of about 0.5-2 microns and contain about 40% of the total proteins of the cell. They play an important role in protecting cells from oxidative stress, which can occur when excess free radicals are produced.

Enzymes contained in peroxisomes help break down hydrogen peroxide and other oxidized compounds. Without these enzymes, cells can become more vulnerable to damage caused by free radicals.

One of the main functions of peroxisomes is cholesterol synthesis. This process involves the conversion of lanosterol to cholesterol, which is then used to create cell membranes.

In addition, peroxisomes may be involved in the metabolism of lipids and carbohydrates. They may also play a role in the regulation of gene expression and cell cycle control.

In general, peroxisomes are important organelles that protect cells from oxidative stress and are involved in various metabolic processes. Their study may lead to new treatments for diseases associated with peroxisome dysfunction.

The peroxisome is a small, relatively independent cell organelle, occupying 5-20% of the total cell volume. Despite their small size, peroxisomes play an important role in many biological processes of cells: they ensure the occurrence of more than two hundred chemical reactions responsible for various physiological processes in the cell.
