Haem

Heme is an iron-containing compound (porphyrin) that, when combined with the protein globin, forms hemoglobin, which is present in red blood cells.

Heme consists of porphyrin and iron ion. The porphyrin ring provides a structure for binding the iron ion and also for interacting with globin. Iron in heme is in the form of Fe2+ and can bind oxygen molecules. Thus, heme performs the most important function of oxygen transport.

Heme is a prosthetic group of hemoglobin and myoglobin. In addition, heme is part of other hemoproteins, such as cytochromes, catalase, and peroxidase. Hemoproteins play a significant role in redox processes in the body.

Heme synthesis occurs in the bone marrow and liver. Impaired synthesis or destruction of heme can lead to the development of diseases such as porphyria and hemolytic anemia. The study of heme metabolism is important for understanding the work of hemoproteins and the mechanisms of development of pathologies associated with them.

Heme: an iron-containing compound that plays an important role in the body

Heme is an iron-containing compound that is a porphyrin, that is, an organic compound containing a ring structure with a central nitrogen atom. Heme is used in the body to create hemoglobin, a protein that transports oxygen to tissues. Heme also plays an important role in other biological processes.

Heme is used to create hemoglobin, a protein found in red blood cells, which are responsible for transporting oxygen in the body. Heme combines with the protein globin to form hemoglobin, which gives blood its red color. Hemoglobin also contains iron, which allows it to bind to oxygen and transport it to tissues.

Heme is also used in other biological processes. For example, it is a key component of cytochromes, proteins that play an important role in the respiratory chain of cells. Heme is also essential for the creation of other hemoproteins that perform various functions in the body, such as electron transport and gas exchange.

Although heme is an important component of the body, its deficiency can lead to various health problems. For example, low hemoglobin levels can be associated with weakness, fatigue and shortness of breath. Heme may also be associated with certain diseases such as anemia and porphyria.

In conclusion, heme (Haem) is an iron-containing compound that plays an important role in the body. It is used to create hemoglobin and other hemoproteins that perform various functions in the body. Heme deficiency can lead to various health problems. Understanding the role of heme in the body can help people maintain their health and prevent various diseases.

Hemoglobin is a complex protein containing iron and found in every blood cell. Its main function is to transport oxygen throughout the body.

Heme is a complex organic compound that has the ability to bind tightly to a number of proteins, forming new complexes. One of them is hemoglobin.

The cells of the human body - lymphocytes, erythrocytes, platelets - contain hemes of various forms, differing in the structure of the iron atom and radicals. The level of cell saturation with iron and its mobility determine the immunological reactivity of the body.

But if hemes contain iron, then what role does iron play in the body? What is its participation in biochemical processes and physiological functions? Iron is bi
