Where can you find phosphate?

Answer 1

Phosphate

Phosphate is a salt and an ester of phosphoric acid with an empirical formula PO3−4 and a molar mass of 94.97 g/mol.d. Phosphorus is widely distributed in the body tissues and fluids. About 80% of total body phosphorus (750 g) is in the bone as insoluble calcium phosphate, and the remaining 15% is in the skeletal muscles.

Absorption: 85% of ingested phosphorus is absorbed. The organic phosphates are digested in the intestines to form inorganic phosphates of sodium, calcium and potassium, and are absorbed from the upper small intestine. Excess calcium and aluminum form insoluble phosphates and decrease phosphate absorption.

Benefits: Necessary for bone formation; intermediate metabolism of Carbohydrates and fats; proper function of enzyme systems; Principal anion in the cells; Phosphate is a part of the molecular structure of phospholipids, an essential element in the phospholipid cell membranes, nucleic acids and phosphoproteins required in mitochondrial function; Is also the source of high energy bonds of ATP. The energy stored in ATP fuels a wide variety of physiological processes.Phosphorus is an essential compound of RNA and DNA, the key components in the structure of cell membranes. The phosphate group is of primary importance in glycolysis. Phosphate is instrumental in maintaining the acid/base balance in the body by acting as a buffer. It also activates many of the vitamin B-Complex vitamins, allowing them to function as coenzymes in various metabolic processes.

Recommended dosage of Phosphate; The daily requirement is about 1 g (32.29 mmol), which is easily supplied in an average diet. Dietary deficiency; therefore, never occurs under normal circumstances.

Phosphate Deficiency symptoms; Low serum phosphorus occurs during starvation, malabsorption; hyperparathyroidism, vitamin D deficiency, diabetic ketoacidosis, acute Alcoholism, severe bums, nasogastric suction, and respiratory alkalosis; and with phosphate-binding antacids, intravenous glucose administration, and high estrogen doses in metastatic prostate cancer.

Clinical Manifestations; Clinically, low phosphate results in loss of appetite, nausea, weakness and malaise, and vitamin D- resistant rickets in children, and osteomalacia in adults. There is increased intestinal calcium absorption and urinary calcium excretion, while urinary phosphate excretion is diminished.

Food sources; Milk and milk products (except their fatty parts, such as cream, butter and ghee), beans, carrot, cauliflower, peas, potato, banana, mushrooms, peanut, fish, cauliflower, lima beans Eggs, pork, lamb liver. Pumpkin seeds are rich in phosphorus and increase urinary phosphate excretion.

Toxicity Levels; can induce an increased fecal excretion of calcium, possibly resulting in a calcium deficiency, can cause diarrhea and calcification (hardening) of organs and soft tissue, and can interfere with the body's ability to use iron, calcium, magnesium, and zinc..
