Myohaemoglobin (Myohaemoglobin), Myoglobin (Myoglobin)

Myohemoglobin and myoglobin are two key protein components that are present in muscle cells and play an important role in ensuring efficient oxygen transport in muscles.

Myohemoglobin and myoglobin are very close in their chemical structure to hemoglobin, which is the main protein responsible for the transport of oxygen through the blood in the human body. Like hemoglobin, myoglobin and myohemoglobin contain iron in their structure, which forms a complex with an oxygen molecule. However, unlike hemoglobin, which is found in red blood cells, myoglobin and myohemoglobin are found inside muscle cells.

Myoglobin is a protein that is responsible for transporting oxygen to the muscles during physical activity. It has a higher oxygen affinity than hemoglobin, allowing it to easily bind oxygen in low muscle oxygen conditions. This allows the muscles to quickly receive oxygen during physical activity, which significantly increases their performance.

Myohemoglobin, in turn, is hemoglobin, which is also found in muscle cells, but has a different function. It serves as an oxygen reservoir and allows muscles to retain the oxygen they need during physical activity. Thus, myohemoglobin provides the muscles with a supply of oxygen that can be used in case of oxygen shortage.

It is important to note that the level of myoglobin and myohemoglobin in the body can be altered due to various factors such as physical activity level, presence of diseases and other factors. For example, myoglobin levels may increase with intense physical activity or with certain medical conditions, such as heart and lung disease. Also, the level of myohemoglobin can decrease with a lack of oxygen in the body.

In conclusion, myoglobin and myohemoglobin are important components that ensure efficient oxygen transport in muscles. Their functions allow muscles to receive oxygen during physical activity and store it as a reserve, which significantly increases performance and promotes the health of the body as a whole.

Myohemoglobin and myoglobin are two different proteins that play an important role in muscle function. Myohemoglobin is a soluble iron-containing pigment protein present in muscle cells. It is very similar to hemoglobin in its chemical composition, as it contains heme, a molecule that binds oxygen. The function of myohemoglobin is to provide muscles with the oxygen they need to function.

Myoglobin, in turn, is also an iron-containing protein pigment, but it is not associated with oxygen. Myoglobin is present in muscles and performs the function of transporting oxygen from capillaries to muscle cells. It also plays an important role in regulating oxygen levels in the muscles, ensuring that it reaches the cells when needed.

Both proteins are important components of the muscular system and are involved in the process of obtaining energy from oxygen. Their interaction and interdependence allow muscles to efficiently use oxygen for energy.

Myohemoglobin and myoglobin are iron-containing proteins that are present in the muscles of humans and animals. Both of them function as oxygen carriers and protect muscle fibers from oxygen deficiency. The article will discuss the physiology and biochemistry of these proteins, as well as their role in the body. The use of these proteins in medicine and sports will also be discussed.

Role in the functioning of the body Myohemoglobin and myoglobin occupy an important position in the sports and physical activity of people. These proteins help reduce recovery time and increase endurance due to their ability to transport oxygen. Physiology Before exercise, myohemoglobins attract large amounts of oxygen from the blood due to the abundance of red blood cells, and fill the muscle cells with it. After training, carbon dioxide and lactic acid penetrate into muscle fibrils, which is formed during the breakdown of glycogen, because of this, muscle tissue goes into a hyperemic state. Thanks to this, myohemoglibin proteins absorb all carbon dioxide gas, and act much more efficiently than hemoglobin from blood plasma. Consequently, during respiration, excess carbon dioxide is not removed from muscle cells through gas exchange, but penetrates through heme bis-carbonate, and the physiological degree of hypoxemia increases due to its cumulation. Biochemistry **Myoglobin and myohemoglobin** are special pigments, identical in structure to hemoglobin, but differing in the amount of iron. Thus, both proteins contain a number of characteristics of hemoglobin, but in addition they may contain lysine, tyrosine or other amino acid residues. Most often these proteins
