Manganese superoxide dismutase (MnSOD) is the principal antioxidant in mitochondria. Several enzymes activated by manganese contribute to the metabolism of carbohydrates, amino acids, and cholesterol. [2] A deficiency of manganese causes skeletal deformation in animals and inhibits the production of collagen in wound healing. [3]
Manganese is also important in photosynthetic oxygen evolution in chloroplasts in plants. The oxygen-evolving complex (OEC) is a part of photosystem II contained in the thylakoid membranes of chloroplasts; it is responsible for the terminal photooxidation of water during the light reactions of photosynthesis , and has a metalloenzyme core ...
Manganese is a critical component in dozens of proteins and enzymes. [8] The human body contains about 12 mg of manganese, mostly in the bones. The soft tissue remainder is concentrated in the liver and kidneys. [9] In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. [101]
Steak is also a good source of vitamin B12, "which is crucial for energy levels, brain health, and red blood cell production," says Alex Larson, a registered dietitian, endurance athlete ...
Put the phone down and grab a book. Whether you prefer a steamy romance novel, a fascinating piece of nonfiction, or a moody mystery, reading boasts tons of benefits for your brain.
Rather than becoming unsafe, they lose potency slowly over time.” If they’re stored in optimal conditions, you can get the most bang for your buck. Best case scenario, the average shelf-life ...
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
Arginase II is coexpressed with nitric oxide (NO) synthase in smooth muscle tissue, such as the muscle in the genitals of both men and women. The contraction and relaxation of these muscles has been attributed to NO synthase, which causes rapid relaxation of smooth muscle tissue and facilitates engorgement of tissue necessary for normal sexual response.
