In the context of nutrition, a mineral is a chemical element. Some "minerals" are essential for life, but most are not. [ 1 ] [ 2 ] [ 3 ] Minerals are one of the four groups of essential nutrients; the others are vitamins , essential fatty acids , and essential amino acids . [ 4 ]
Inosilicates contain two important rock-forming mineral groups; single-chain silicates are most commonly pyroxenes, while double-chain silicates are often amphiboles. [118] Higher-order chains exist (e.g. three-member, four-member, five-member chains, etc.) but they are rare. [119] The pyroxene group consists of 21 mineral species. [120]
The soil mineral apatite is the most common mineral source of phosphorus, from which it can be extracted by microbial and root exudates, [79] [80] with an important contribution of arbuscular mycorrhizal fungi. [81] The most common form of organic phosphate is phytate, the principal storage form of phosphorus in many plant tissues.
Two important types of these relationship are with bacteria such as rhizobia, that carry out biological nitrogen fixation, in which atmospheric nitrogen (N 2) is converted into ammonium (NH + 4); and; with mycorrhizal fungi, which through their association with the plant roots help to create a larger effective root surface area. Both of these ...
Vitamins and minerals are essential to the proper functioning and maintenance of the human body. [114] There are 20 trace elements and minerals that are essential in small quantities to body function and overall human health. [114] Iron deficiency is the most common inadequate nutrient worldwide, affecting approximately 2 billion people. [115]
This is a list of minerals which have Wikipedia articles. Minerals are distinguished by various chemical and physical properties.
Mineralogy applies principles of chemistry, geology, physics and materials science to the study of minerals. Mineralogy [n 1] is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.
Silicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust . [ 1 ] [ 2 ] [ 3 ]
