Definitions for "Manganese"
An element obtained by reduction of its oxide, as a hard, grayish white metal, fusible with difficulty (melting point 1244° C), but easily oxidized. Its ores occur abundantly in nature as the minerals pyrolusite, manganite, etc. Symbol Mn. Atomic number 25; Atomic weight 54.938 [C=12.011].
Symbol: Mn. Atomic mass: 54.938. A hard, brittle, grayish-white metallic element that is used as an alloy to make hardened steel.
Element (Atomic # - 25 Atomic Weight - 54.93) Manganese increases the hardness of iron and steel. Will reduce sulfur problems by forming MnS stringers. High percentages (12%)of Mn in steel stabilizes the austenitic phase and behaves like a stainless (non-magnetic). These steels are sometimes called "Hadfield" steels for the man who discovered them. They "work harden" in that they get harder by beating on them and therefore make great wear parts like shredder hammers, grates, and railroad frogs.
An essential trace mineral needed for normal bone matabolism and many enzyme reactions.
functions in many enzyme systems including those involved in blood sugar control, energy metabolism, and thyroid hormone function. Like copper and zinc, manganese also functions in the antioxidant enzyme, super-oxide dismutase. Imbalances contribute to poor bone and connective tissue growth, skin dryness, hair loss, allergies, and some behavior problems. Good dietary sources of manganese include nuts, whole grains, dried fruits, and green leafy vegetables.
a mineral that is a cofactor in many enzyme systems including those involved in bone formation, energy production and protein metabolism. No RDA has been established.

Manganese is an amino acid (see amino acid) and is an important component of cartilage as well as helps synthesis glucosamine.
Micronutrient critical for plant growth, usually found as the manganous oxide anion in soil.
As A Treatment"Sometimes called a "cell protector", the name manganese comes from the Greek word for magic, because it was thought to have magical properties..."
