| magnesium chelatase | <enzyme> Catalyses the first committed step in chlorophyll biosynthesis by adding magnesium to protoporphyrin ix Registry number: EC 4.99.1- Synonym: mg-chelatase, magnesium-protoporphyrin chelatase (26 Jun 1999) |
| magnesium chloride | <chemical> Magnesium chloride. An inorganic compound consisting of one magnesium and two chloride ions. The compound is used in medicine as a source of magnesium ions, which are essential for many cellular activities. It has also been used as a cathartic and in alloys. Chemical name: Magnesium chloride (MgCl2) (12 Dec 1998) |
| magnesium citrate | Mg3(C6H5O7)2-14H 2O;a laxative; usually administered as an effervescent flavored beverage. (05 Mar 2000) |
| magnesium compounds | Inorganic compounds that contain magnesium as an integral part of the molecule. (12 Dec 1998) |
| magnesium deficiency | Can occur due to inadequate intake or impaired intestinal absorption of magnesium. Low magnesium (hypomagnesaemia) is often associated with low calcium (hypocalcaemia) and low potassium (hypokalaemia). Deficiency of magnesium causes increased irritability of the nervous system with tetany (spasms of the hands and feet, muscular twitching and cramps, spasm of the larynx, etc.). According to the national academy of sciences, the recommended dietary allowances of magnesium are 420 milligrams per day for men and 320 milligrams per day for women. The upper limit of magnesium as supplements is 350 milligrams daily, in addition to the magnesium from food and water. (12 Dec 1998) |
| magnesium excess | Persons with impaired kidney function should be especially careful about their magnesium intake because they can accumulate magnesium, a dangerous situation. According to the national academy of sciences, the recommended dietary allowances of magnesium are 420 milligrams per day for men and 320 milligrams per day for women. The upper limit of magnesium as supplements is 350 milligrams daily, in addition to the magnesium from food and water. (12 Dec 1998) |
| magnesium hydroxide | <chemical> Magnesium hydroxide (mg(oh)2). An inorganic compound that occurs in nature as the mineral brucite. It acts as an antacid with cathartic effects. Pharmacological action: antacids, cathartic. Chemical name: Magnesium hydroxide (Mg(OH)2) (12 Dec 1998) |
| magnesium lactate | A laxative. (05 Mar 2000) |
| magnesium oxide | <chemical> Magnesium oxide (mgo). An inorganic compound that occurs in nature as the mineral periclase. In aqueous media combines quickly with water to form magnesium hydroxide. It is used as an antacid and mild laxative and has many nonmedicinal uses. Pharmacological action: antacids, cathartic. Chemical name: Magnesium oxide (MgO) (12 Dec 1998) |
| magnesium peroxide | Decomposes in water to hydrogen peroxide; used as an ingredient in dentifrices and in antiseptic dusting powder. (05 Mar 2000) |
| magnesium phytinates | Chlorophyll a and b. See entries under chlorophyll. (05 Mar 2000) |
