| hypophosphataemia | <biochemistry> An abnormally low serum phosphate level. Normal serum phosphate levels are in the range of 2.5 to 4.5 mg/dl. Origin: Gr. Haima = blood (11 Jan 1998) |
| hypophosphatasaemia | A genetic metabolic disorder resulting from serum and bone alkaline phosphatase deficiency leading to hypercalcaemia, ethanolamine phosphatemia, and ethanolamine phosphaturia. Clinical manifestations include severe skeletal defects resembling vitamin d-resistant rickets, failure of the calvarium to calcify, dyspnea, cyanosis, vomiting, constipation, renal calcinosis, failure to thrive, disorders of movement, beading of the costochondral junction, and rachitic bone changes.

| hypophosphate | <chemistry> A salt of hypophosphoric acid. Source: Websters Dictionary (01 Mar 1998) |
| hypophosphatemia | An abnormally decreased level of phosphates in the blood. The manifestations include haemolysis, lassitude, weakness, and convulsions. It may be found in hyperparathyroidism, rickets, osteomalacia, and several renal tubular abnormalities. (12 Dec 1998) |
| hypophosphatemia, familial | Familial disorder characterised by hypophosphatemia associated with decreased renal tubular reabsorption of inorganic phosphorus. It is sometimes associated with osteomalacia or rickets which do not respond to the usual doses of vitamin d. (12 Dec 1998) |
| hypophosphaturia | Reduced urinary excretion of phosphates. (05 Mar 2000) |

| hypophosphoric | <chemistry> Pertaining to, or derived from, or containing, phosphorus in a lower state of oxidation than in phosphoric compounds; as, hypophosphoric acid. <chemistry> Hypophosphoric acid, an acid, P2H4O6, produced by the slow oxidation of moist phosphorus, and isolated only as a solution in water. It is regarded as a condensation product of one molecule of phosphoric acid with one of phosphorous acid, by partial dehydration. Origin: Pref. Hypo- + phosphoric.

| hypophosphorous | <chemistry> Pertaining to, or containing, phosphorus in a lower state of oxidation than in phosphoric compounds; as, hypophosphorous acid. <chemistry> Hypophosphorous acid, an acid, H3PO2, whose salts are produced by the action of barium hygrate on phosphorus. It may be obtained from its water solution, by exaporation and freezing, as a white crystalline substance. It is a powerful reducing agent. Origin: Pref. Hypo- + phosphorous.
