Phosphorite - Wikipedia

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.This occurs through washing, screening ...

It's a central atom in the backbone of DNA, shared by every living creature on earth, and it is used by human cells in adenosine triphosphate (ATP) as the primary means of energy storage. In the natural phosphorus cycle, mineral phosphate is freed from rock by erosion, makes its way into soil, and is absorbed by plants.

Rho-associated protein kinase - Wikipedia

Rho-associated protein kinase (ROCK) is a kinase belonging to the AGC (PKA/ PKG/PKC) family of serine-threonine kinases.It is involved mainly in regulating the shape and movement of cells by acting on the cytoskeleton.. ROCKs (ROCK1 and ROCK2) occur in mammals (human, rat, mouse, cow), zebrafish, Xenopus, invertebrates (C. elegans, mosquito, Drosophila) and chicken.

An increase in the phosphate load can also cause hyperphosphatemia, whether from an exogenous source, such as phosphate administration, or an endogenous source, as observed in rhabdomyolysis or tumor lysis syndrome. In these cases, cells are lysed, and phosphate is released from within the cell, increasing the extracellular concentration.
