| sulfathiazole | 2-Sulfanilylaminothiazole; 2-(p-aminobenzenesulfonamido)thiazole;an antibacterial agent of the sulfonamide group. (05 Mar 2000) |
|---|---|
| sulfathiazoles | <chemical> Pharmacological action: anti-infective agents. (12 Dec 1998) |
| sulfatidates | Cerebroside sulfuric esters containing one or more sulfate groups in the sugar portion of the molecule. Synonym: sulfatidates. (05 Mar 2000) |
| sulfatide lipidosis | <radiology> Dysmyelinating disease, autosomal recessive, aryl sulfatase A -- absent from urine and serum, most present by 2 yrs, die at 3-4 yrs, may arise at any age, CT: decreased density of white matter, primarily in centrum semiovale, with or without focal gall bladder defects (!) (12 Dec 1998) |
| sulfatides | Cerebroside sulfuric esters containing one or more sulfate groups in the sugar portion of the molecule. Synonym: sulfatidates. (05 Mar 2000) |
| sulfatidosis | A combination of metachromatic leukodystrophy and mucopolysaccharidosis caused by deficiency of sulfatase enzymes such as arylsulfatases A, B, and C, and steroid sulfatases; characterised by coarse facial features, ichthyosis, hepatosplenomegaly, and skeletal abnormalities, with increased urinary excretion of dermatan and heparan sulfates. See: metachromatic leukodystrophy. (05 Mar 2000) |
| sulfation | Addition of sulfate groups as esters to preexisting molecules. (05 Mar 2000) |
| sulfation factor | <protein> Peptide hormone (4 kD) that is produced in the liver and is released in response to somatotropin. Somatomedin stimulates the growth of bone and muscle and also influences calcium, phosphate, carbohydrate and lipid metabolism. See: insulin like growth factor. (18 Nov 1997) |
| sulfenic acids | Oxy acids of sulfur with the general formula rsoh, where r is an alkyl or aryl group such as ch3. They are often encountered as esters and halides. (12 Dec 1998) |
| sulfhemoglobin | <chemical> Chemical name: Haemoglobins, sulf- (12 Dec 1998) |
| sulfhemoglobinaemia | A morbid condition due to the presence of sulfmethemoglobin in the blood. It is marked by persistent cyanosis, but the blood count does not reveal any special abnormality in the blood. It is thought to be caused by the action of hydrogen sulfide absorbed from the intestine. (12 Dec 1998) |
| sulfhydrate | A compound (hydrosulfide) containing the ion HS-. Synonym: sulfohydrate. (05 Mar 2000) |
| sulfhydryl | The radical -SH; contained in glutathione, cysteine, coenzyme A, lipoamide (all in the reduced state), and in mercaptans (R-SH). Synonym: thiel. (05 Mar 2000) |
| sulfhydryl compounds | Compounds containing the -sh radical. (12 Dec 1998) |
| sulfhydryl oxidase | <enzyme> 2rsh plus 02 gives rssr plus hydrogen peroxide; substrate sulfhydryl compounds may be replaced by glutathione or other specific as appropriate Registry number: EC 1.8.3.- Synonym: sulphydryl oxidase, s-s cross-linking enzyme, sulphydryloxidase (26 Jun 1999) |
