Aluminum biological function

Heavy metals with no known biological function, such as aluminum, arsenic, lead, and mercury, are nonessential metals.4-5 These metals are toxic because they can irreversibly bind to enzymes that require metal cofactors. Toxic metals readily bind to sulfhydryl groups of proteins.6-7 In fact,... 

Biological and clinical chemistry applications of plasma emission spectrometry include determinations of those metals required for proper functioning of living systems, such as Fe, Cu, K, Na, P, S, and Se, in urine, blood, serum, bone, muscle, and brain tissue. Aluminum exposure was suspected of playing a role in Alzheimer s disease and A1 concentrations in blood and tissue can be determined by emission spectrometry. No link between exposure to aluminum and Alzheimer s... 

Inasmuch as soil is bio inert system which has formed under the influence of biological factors it is inherent the function of conservation and transformation of substances [12, 13] and it reacts to soluble phosphorous fertilizer application according to Le Chatelier principle If a system at equilibrium experiences a change then the equilibrium shifts to partially counter-act the imposed change [14]. In different soils these functions are manifested in accordance with root natural causes. In soddy-podzolic soils with increased iron and aluminum compounds content applied phosphorous fertilizers transform in phosphate sesquioxides while in carbonate-enriched chernozems and chestnut soils the function of phosphoms conservation manifests itself in emergence of phosphates with different basicity including sparing soluble compounds, for example, apatite. Obviously the specific reasons determined a small increase or...
