| gelatin sugar | <amino acid, physiology> The simplest amino acid. It is a common residue in proteins, especially collagen and elastin and is not optically active. It is also a major inhibitory neurotransmitter in spinal cord and brainstem of vertebrate central nervous system. (18 Nov 1997) |

| absorbable gelatin film | A sterile, nonantigenic, absorbable, water-insoluble, thin sheet of gelatin prepared by drying a gelatin-formaldehyde solution on plates; used in the closure and repair of defects in membranes such as the dura mater or the pleura; it undergoes absorption over a period of 1 to 6 months. (05 Mar 2000) |
|---|---|
| absorbable gelatin sponge | A sterile, absorbable, water-insoluble gelatin base sponge, used to control capillary bleeding in surgical operations; it is left in situ and is absorbed in from 4 to 6 weeks. (05 Mar 2000) |
| vegetable gelatin | A substance similar to gelatin, obtained from gluten. (05 Mar 2000) |
| gelatin | <protein> Heat denatured collagen. (18 Nov 1997) |
| gelatin sponge, absorbable | <chemical> Sterile, gelatin-base surgical sponge applied topically as an adjunct to haemostasis when the control of bleeding by conventional procedures is ineffective to reduce capillary ooze or is impractical. Pharmacological action: haemostatics. (12 Dec 1998) |
| glycerinated gelatin | A preparation made of equal parts of gelatin and glycerin; a firm mass liquefying at gentle heat; it is used as a vehicle for suppositories and urethral bougies. Synonym: glycerin jelly, glycerogelatin, glycogelatin. (05 Mar 2000) |
| Guarnieri's gelatin agar | A type of agar, similar to Stoddart's gelatin agar, used for the cultivation of Streptococcus pneumoniae. (05 Mar 2000) |
| Irish moss gelatin | Gelatin extracted from Irish moss; used to make the mucilage of Irish moss that is used as a substitute for gum arabic in making emulsions. (05 Mar 2000) |
| zinc gelatin | Zinc oxide, gelatin, glycerin, and purified water; used topically as a protectant. (05 Mar 2000) |
| amino sugar | <biochemistry> Monosaccharide in which an OH group is replaced with an amino group, often acetylated. Common examples are D galactosamine, D glucosamine, neuraminic acid, muramic acid. Amino sugars are important constituents of bacterial cell walls, some antibiotics, blood group substances, milk oligosaccharides and chitin. (18 Nov 1997) |
| beechwood sugar | D-xylose. See: xylose. (05 Mar 2000) |
| beet sugar | D-sucrose. See: sucrose. (05 Mar 2000) |
| blood sugar, high | Elevated levels of blood glucose (hyperglycaemia) can be found in a number of conditions. The hyperglycaemia leads to spillage of glucose into the urine, hence the term sweet urine. (Diabetes mellitus means sweet urine. ) (12 Dec 1998) |
| blood sugar, low | The sugar here is glucose. Low blood glucose constitutes hypoglycaemia. Hypoglycaemia is only significant when it is associated with symptoms. It has many causes including drugs, liver disease, surgical absence of the stomach, pre-diabetes, and rare tumours that release excess insulin. (12 Dec 1998) |
| malt sugar | <biochemistry> Disaccharide intermediate of the breakdown of starch, glucose _(1-4) glucose. Fermentable substrate in brewing. (20 Mar 1998) |
