4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Fertilizers

Substances or mixtures that are added to the soil to supply nutrients or to make available nutrients already present in the soil, in order to increase plant growth and productivity. (See all compounds classified as Fertilizers.)


Food Additives

Substances used in the processing or storage of foods or animal feed including ANTIOXIDANTS; FOOD PRESERVATIVES; FOOD COLORING AGENTS; FLAVORING AGENTS; ANTI-INFECTIVE AGENTS; EXCIPIENTS and other similarly used substances. Many of the same substances are used as PHARMACEUTIC AIDS. (See all compounds classified as Food Additives.)


4.2 Absorption, Distribution and Excretion

/Ortho/ phosphate is absorbed from, and to a limited extent secreted into, the gastrointestinal tract. Transport of phosphate from the gut lumen is an active, energy-dependent process that is modified by several factors. ... Vitamin D stimulates phosphate absorption, an effect reported to precede its action on calcium ion transport. In adults, about two thirds of the ingested phosphate is absorbed, and that which is absorbed is almost entirely excreted into the urine. In growing children, phosphate balance is positive. Concentrations of phosphate in plasma are higher in children than in adults. This "hyperphosphatemia" decreases the affinity of hemoglobin for oxygen and is hypothesized to explain the physiological "anemia" of childhood. /Phosphates/

4.3 Metabolism/Metabolites

A defect in phosphate metabolism occurs in a variety of diseases. ... Rickets ... Osteomalacia ... Primary or Secondary Hyperparathyroidism ... Chronic Renal Failure. /Phosphates/
