Lipid composition of human labial salivary gland secretions. 1983

B L Slomiany, and E Zdebska, and V L Murty, and A Slomiany, and K Petropoulou, and I D Mandel

Extraction of the dialysed and lyophilized labial saliva with chloroform/methanol yielded 423.8 +/- 73.0 micrograms of lipids/ml of saliva, a level 4-5 times higher than in the major salivary glands. Of the total lipids, 32.4 per cent were represented by neutral lipids, 44.6 per cent by glycolipids and 23.0 per cent by phospholipids. Neutral lipids had a high content of free fatty acids (43.8 per cent), cholesteryl esters (26.9 per cent) and triglycerides (15.4 per cent). The glycolipids consisted mainly of neutral (74.6 per cent) and sulphated (25.4 per cent) glyceroglucolipids, whereas phosphatidylethanolamine, phosphatidylcholine, sphingomyelin and phosphatidylserine accounted for 54.7 per cent of the total phospholipids.

UI MeSH Term Description Entries
D008046 Lip Either of the two fleshy, full-blooded margins of the mouth. Philtrum,Lips,Philtrums
D008055 Lipids A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids. (Grant & Hackh's Chemical Dictionary, 5th ed) Lipid
D010743 Phospholipids Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system. Phosphatides,Phospholipid
D005227 Fatty Acids Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (FATTY ACIDS, UNSATURATED). (Grant & Hackh's Chemical Dictionary, 5th ed) Aliphatic Acid,Esterified Fatty Acid,Fatty Acid,Fatty Acids, Esterified,Fatty Acids, Saturated,Saturated Fatty Acid,Aliphatic Acids,Acid, Aliphatic,Acid, Esterified Fatty,Acid, Saturated Fatty,Esterified Fatty Acids,Fatty Acid, Esterified,Fatty Acid, Saturated,Saturated Fatty Acids
D006017 Glycolipids Any compound containing one or more monosaccharide residues bound by a glycosidic linkage to a hydrophobic moiety such as an acylglycerol (see GLYCERIDES), a sphingoid, a ceramide (CERAMIDES) (N-acylsphingoid) or a prenyl phosphate. (From IUPAC's webpage) Glycolipid
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D012463 Saliva The clear, viscous fluid secreted by the SALIVARY GLANDS and mucous glands of the mouth. It contains MUCINS, water, organic salts, and ptylin. Salivas
D012469 Salivary Glands Glands that secrete SALIVA in the MOUTH. There are three pairs of salivary glands (PAROTID GLAND; SUBLINGUAL GLAND; SUBMANDIBULAR GLAND). Gland, Salivary,Glands, Salivary,Salivary Gland
D012470 Salivary Glands, Minor Accessory salivary glands located in the lip, cheek, tongue, floor of mouth, palate and intramaxillary. Gland, Minor Salivary,Glands, Minor Salivary,Minor Salivary Gland,Minor Salivary Glands,Salivary Gland, Minor
