For example, iron is a trace element in the human body, while it is a major element in the Earth's crust. The human body and the Earth's crust have their own set of trace elements. Trace element examples in the human body include: Iron Copper Zinc Trace element examples in the Earth...
Alternatively, when minerals act as cofactors, they become a part of the enzyme or protein structure that is essential for the biochemical reaction to proceed. Minerals that act as cofactors include manganese, selenium, magnesium, and molybdenum. Some minerals, such as cobalt, iodine, calcium, ...
Soil microorganisms are present in high numbers and have a wide range of metabolic activities and physiological properties that play a vital role in the cycling of nutrients within the soil and are essential for the removal of pollutants from soil. The soil contains a wide range of substrates fo...

The ultramafic-hosted Kairei vent field is located at 25°19′ S, 70°02′ E, towards the Northern end of segment 1 of the Central Indian Ridge (CIR-S1) at a water depth of ~2450 m. This study aims to investigate the distribution of trace elements among sulfide minerals of differing...
This study aims to investigate the distribution of trace elements among sulfide minerals of differing textures and to examine the possible factors controlling the trace element distribution in those minerals using LA-ICP-MS spot and line scan analyses. Our results show that there are distinct ...
Because of these features, plants are considered essential to favor the transition to a bio-economy that is less dependent on fossil resources. Plants synthesize a huge variety of secondary metabolites, with complex chemical composition, which are produced in response to different forms of (a) ...
Notably, peculiarities of countries and regions make the cultural frame of geoheritage very different. On the other hand, essentially artificial heritage features, which can be interpreted as geoheritage, are still poorly-known. This may not only include mines or tunnels created to modify the ...
It is important to note that animal cells cannot synthesize from simple compounds certain necessary complex molecules. Instead, certain large organic molecules must serve as building blocks; such so-called essential dietary components include the vitamins, some amino acids, and certain fatty substances....
