| sodium dodecyl sulfate | <chemical> An anionic surfactant, usually a mixture of sodium alkyl sulfates, mainly the lauryl; lowers surface tension of aqueous solutions; used as fat emulsifier, wetting agent, detergent in cosmetics, pharmaceuticals and toothpastes; also as research tool in protein biochemistry. Pharmacological action: surface-active agent. Chemical name: Sulfuric acid monododecyl ester sodium salt (12 Dec 1998) |

| sodium erythorbate | <chemical> This compound is used in the food industry to keep processed meat, such as hot dogs and beef sticks, from turning strange colours. It is chemically similar to vitamin C, which was used for the same purpose before this compound, but only gives the body 1/20th of the vitamin C one would get from taking regular vitamin C. It is made from sugar, commonly beet and cane sugar. (09 Oct 1997) |
| sodium fluoride | <chemical> Sodium fluoride (naf). A source of inorganic fluoride which has been used orally and topically to prevent dental caries. It is also effective as a pesticide and in the therapy of osteoporosis. Pharmacological action: fluorides, topical. Chemical name: Sodium fluoride (NaF) (12 Dec 1998) |
| sodium fluosilicate | Na2SiF6;used (in dilute solutions) as an antiseptic and deodorant, and for fluoridation of drinking water. Synonym: sodium fluosilicate, sodium silicofluoride. (05 Mar 2000) |
| sodium folate | The sodium salt of folic acid; action and uses are the same as those of folic acid, but it is preferred for parenteral administration. Synonym: sodium pteroylglutamate. (05 Mar 2000) |
| sodium fusidate | The sodium salt of fusidic acid; has antibacterial properties. Synonym: sodium fusidate. (05 Mar 2000) |
| sodium glutamate | <chemical> L-glutamic acid, sodium salt. An additive used to impart meat flavor to foods, and to enhance other natural food flavors. Medically it has been used to reduce blood ammonia levels in ammoniacal azotemia, therapy of hepatic coma, in psychosis, and mental retardation. Pharmacological action: food additives. Chemical name: L-Glutamic acid, monosodium salt (12 Dec 1998) |

| sodium group | The alkali metals: cesium, lithium, potassium, rubidium, and sodium. (05 Mar 2000) |
| sodium hexafluorosilicate | Na2SiF6;used (in dilute solutions) as an antiseptic and deodorant, and for fluoridation of drinking water. Synonym: sodium fluosilicate, sodium silicofluoride. (05 Mar 2000) |
| sodium-hydrogen antiporter | A plasma membrane exchange glycoprotein transporter that functions in intracellular pH regulation, cell volume regulation, and cellular response to many different hormones and mitogens. (12 Dec 1998) |
| sodium hydrogen carbonate | <chemical> Carbonic acid monosodium salt (CHNaO3). A white, crystalline powder that is used as an electrolyte replenisher and systemic alkaliser. It is applied topically in solution to wash the nose, mouth, or vagina, and as a cleansing enema. Pharmacologic action: Acid neutralization. Uses: Preexisting metabolic acidosis, hyperkalemia, tricyclic or phenobarbital overdose. Dose in mEq: 0.3 * (base deficit) * (wt in kg). Potential complications: Metabolic alkalosis, hypercarbia, hyperosmolar state. Note: Since HCO3- does not cross cell membranes and CO2 does, the administration of bicarbonate may actually make tissues more acidotic. Chemical name: Carbonic acid monosodium salt. (12 Mar 2000) |
| sodium hydrogen sulfite | NaHSO3;acid sodium sulfite, used in gastric and intestinal fermentation, externally in the treatment of parasitic diseases, and as an antioxidant in certain injections (s. Metabisulfite). Synonym: sodium hydrogen sulfite, sodium pyrosulfite. (05 Mar 2000) |
