Among the globulin proteins that contain heme, hemoglobin (Hb) has been studied the most, but its functions are still unclear. One of the first proteins to be examined by X-ray crystallography, it was awarded Max Perutz the 1962 Chemistry Nobel Prize. Numerous data from the structural studies revealed amazing molecular principles underlying the physiological functions of hemoglobin. According to Kosmachevskaya and Topunov (2018), hemoglobin is a polyfunctional molecule that is involved in a number of processes, including nitric oxide metabolism, metabolic reprogramming, pH regulation, redox balance maintenance, and catalysis (nitrite reductase, NO dioxygenase, monooxygenase, alkylhydroperoxidase, esterase, lipoxygenase). However, the main focus of this chapter is on the oxygen transport function of hemoglobin and how hemoglobin allostery is affected by mutations, endogenous or exogenous ligands, or effectors.
The blood's vital component, hemoglobin, transports oxygen from the lungs to various bodily areas. Anemia, lethargy, and weariness can result from low hemoglobin levels. Getting adequate iron and other nutrients that aid in the formation of hemoglobin might be difficult in India, where vegetarianism is prevalent.
The most crucial component needed for hemoglobin to develop and function properly in the human body is iron. Unfortunately, due to dietary and absorption restrictions, iron insufficiency is the most prevalent type of element shortage in people.
Iron is the most important element that is required for the formation and effective functioning of hemoglobin in the human body. Unfortunately iron deficiency is the most common form of element that is found deficient in the humans owing to dietary and absorptive limitations.
- Traditional Indian foods like ragi, jaggery, and amaranth are excellent sources of iron and other essential nutrients that can help boost hemoglobin levels.
Elevated hemoglobin levels may indicate the rare blood condition known as polycythemia (Trusted Source). The body produces an excessive amount of red blood cells in polycythemia, which results in thicker-than-normal blood. Clots, heart attacks, and strokes may result from this. Without treatment, this dangerous, chronic illness has the potential to be lethal.
Anemia is usually diagnosed by low hemoglobin levels. Numerous types of anemia exist (Trusted Source):
The most prevalent kind of anemia that results from a person's body not having enough iron to produce the necessary amounts of hemoglobin is iron-deficiency anemia. It usually results from blood loss, however it can also occur from insufficient iron absorption by the body. For instance, after undergoing gastric bypass surgery, this may occur.
