Manganese Absorption and Metabolism

Manganese, a vital trace mineral essential for all living organisms, plays a pivotal role in the consistent development, growth, and functioning of the human body. It serves as a cofactor for a diverse range of enzymes, including manganese superoxide dismutase, arginase, and pyruvate carboxylase. Brown rice, rice bran, wheat bran, wheat germ, molasses, beans, nuts, and tea are notable for being excellent sources of whole foods rich in manganese.

The absorption of manganese predominantly takes place in the small intestine through an active transport system, with the possibility of diffusion at elevated intake levels. Regulatory mechanisms ensure that an uptick in dietary manganese intake leads to a reduction in gastrointestinal absorption. Following absorption, some manganese remains unbound, while the majority binds to transferrin, albumin, and plasma alpha-2-macroglobulin. Although the process of manganese uptake by the liver and other tissues is not fully understood, it is generally acknowledged as a mineral with absorption rates that are less than optimal.

Various elements, such as fiber, phosphorus, oxalates, and iron, can impede manganese absorption, and alkalinity may diminish manganese uptake. The liver expedites the elimination of manganese from the bloodstream through biliary excretion, with less than 5 percent of ingested manganese typically being absorbed by adults.

Numerous enzymes activated by manganese play pivotal roles in the metabolism of carbohydrates, amino acids, and cholesterol.

Manganese function in the production of mother’s milk

Manganese is the 12th most abundant element in the Erath’s crust and constitutes approximately o.1% of it.

Manganese is involved in reproductive functions and helps produce mother’s milk. In humans, gastrointestinal absorption of manganese is greatly increased in pregnant mother and in newborns.

The manganese content is most valuable for mothers during times of lactation as it stimulates gland secretions that promote the development of mother’s milk.

Manganese occurs predominately in the whey fraction of human milk (71%), most of which is associated with lactoferrin. Eighteen percent is found in the lipid layer and 11% is associated with casein.

Owing to the weak binding of manganese to some organic ligands, most manganese species in human milk are considered to be labile.

The largest quantities of manganese are found in avocadoes, nuts, and seeds, seaweed and whole grains. This mineral may also found in blueberries, egg yolks, legumes, dried peas, pineapples, spinach and green leafy vegetables.

Deficiency of manganese

A deficiency of manganese (which is extremely rare) may lead to atherosclerosis, confusion, eye problems, hearing problems, heart disorders, high cholesterol levels, hypertension irritability, memory loss, muscle contradiction, pancreatic damage, profuse perspiration, rapid pulse, teeth grinding, tremors and a tendency towards breast ailments.

Although people who consume normal varied diets do not appear to be at risk for manganese deficiency, certain disorders may cause suboptimal status.

Manganese deficiency has been shown to lead to bone demineralization and impaired growth in children, decreased serum cholesterol levels and a transient skin rash in young men, and mildly abnormal glucose tolerance in young women.

Manganese in Our Body

Minute quantities of manganese are needed for protein and fat metabolism, healthy nerves, a healthy immune system, and blood sugar regulation.

Body contains between 10 to 20 milligram of manganese, which is concentrated primarily in the bone, liver, pancreas and brain.

Manganese is used in energy production and is required for normal bone growth and for reproduction.

In addition, it is used in the formation of cartilage and synovial (lubricating) fluid of the joints. It is also necessary for the synthesis of bone.

Too little dietary manganese causes impaired skeletal development and reproduction, abnormal carbohydrate and lipid metabolism, and movement disorders.

Manganese is essential for people with iron deficiency anemia and is needed for the utilization of vitamin B1 (thiamine) and vitamin E.

Manganese works well with the B complex vitamins to give as overall feeling of well being.

Manganese is found in many essential enzymes, which are biologically important compounds. Enzymes in the body speed up crucial chemical reactions.

It aids in the formation of mother’s milk and is a key element in the production of enzymes needed to oxidize fats and to metabolize purines, including the antioxidant enzymes superoxide dismutase.

Enzymes containing manganese protect the body from harmful oxygen radicals, highly reactive oxygen containing molecules that can damage living tissues.

Absorption of manganese is poor, only 1 to 15 percent. The high levels of iron, calcium an phosphorus may inhibit absorption.

Following absorption, transferring binds manganese and transport it in the bloodstream.

Contributions of Manganese

Contributions of Manganese
Manganese is a trace mineral that takes part in a wide range of metabolic functions. While more needs to be learned about the activities of this mineral research shows that having sufficient manganese is essential for health.

It plays a part in protein, carbohydrate and fat metabolism and helps regulate blood sugar.

Manganese contributes to home development the formation of blood, collagen formation, protein digestion, the production of mother’s milk and the formation of urea, purine metabolism, and the immune system.

It is a catalyst in the synthesis of fatty acids, cholesterol and mucopolysaccharides.

Manganese is essential for the formation of thyroxine, the hormone produced by the thyroid gland that regulates metabolism.

Healthy nerves and brain and the maintenance of sex hormone production are functions of manganese.

Prothrombin and vitamin K are formed with the help of manganese, and this mineral is important for the body’s utilization of vitamin E and the treatment of iron-deficiency anemia.

This mineral plays a role in activating numerous enzymes involved in energy production and inactivating free radicals.

Some allows for the utilization of choline, biotin, thiamin and vitamin C.

Manganese also functions in the special antioxidant enzyme superoxide dismutase (SOD), which helps protect cells from damage and inflammation.

The richest dietary sources of manganese are nuts, whole grains, dried fruits and green leafy vegetables, Pecans, brazil nuts, and almonds contain plentiful manganese.

Rye, brown rice, lentils, pineapple, blackberries, sweet potato, chickpeas and persimmon are also relatively high sources of manganese.

Function of manganese in Nutrition

Function of manganese in Nutrition
The adult body contains about 20 mg of manganese, found mainly in the liver, pancreas pituitary gland and bone.

Although it is considered a dietary essential, manganese is also toxic at high levels.

Manganese functions like other trace elements as an essential part of cell enzymes that catalyze any important metabolic reactions.

Absorption and retention of manganese are associated with serum ferritin concentration.

Manganese deficiency is rare, but it has been reported in cases of diabetes and pancreatic insufficiency and in protein-energy malnutrition states such as kwashiorkor.

Manganese toxicity occurs as an industrial disease, inhalation toxicity, in miners and other workers with prolonged exposure to manganese dust.

The excess manganese accumulates in the liver and central nervous system, producing severe neuromuscular symptoms similar to those of Parkinson’s disease.

The best food sources of manganese are of plant origin. Whole grain, cereal products and teas are the richest food sources, and fruits and vegetables are somewhat less rich.

Dairy products, meat fish and poultry are poor sources of manganese.
