Structure of the O-glycosidically linked carbohydrate units of rat brain glycoproteins. 1975

J Finne

The O-glycosidically linked carbohydrate units of rat brain glycopeptides were released as reduced oligosaccharides with NaOH/NaBH4 treatment. Five oligosaccharides were isolated using gel filtration, ion-exchange chromatography and preparative thin-layer chromatography. Studies employing periodate oxidation, methylation analysis, chromium trixide oxidation and gas-liquid chromatography-mass spectrometry indicated the following structures: (I) alpha-galactosyl-(1 leads to 3)-N-acetylgalactosaminitol, (II) beta-galactosyl-(1 leads to 3)-N-acetylgalactosaminitol, (III) N-acetylneuraminyl-[beta-galactosyl-(1 leads to 3)-N-acetylgalactosaminitol], (IV) N-acetylneuraminyl-(2 leads to 3)-beta-galactosyl-(1 leads to 3)-N-acetylgalactosaminitol and (V) N-acetylneuraminyl-(2 leads to 3)-beta-galactosyl-(1 leads to 3)[N-acetylneuraminyl-(2 leads to 6)]-N-acetylgalactosaminitol.

D008297	Male		Males
D009844	Oligosaccharides	Carbohydrates consisting of between two (DISACCHARIDES) and ten MONOSACCHARIDES connected by either an alpha- or beta-glycosidic link. They are found throughout nature in both the free and bound form.	Oligosaccharide
D001894	Borohydrides	A class of inorganic or organic compounds that contain the borohydride (BH4-) anion.	Borohydride
D001923	Brain Chemistry	Changes in the amounts of various chemicals (neurotransmitters, receptors, enzymes, and other metabolites) specific to the area of the central nervous system contained within the head. These are monitored over time, during sensory stimulation, or under different disease states.	Chemistry, Brain,Brain Chemistries,Chemistries, Brain

D005688	Galactosamine
D005690	Galactose	An aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins. Deficiency of galactosyl-1-phosphate uridyltransferase (GALACTOSE-1-PHOSPHATE URIDYL-TRANSFERASE DEFICIENCY DISEASE) causes an error in galactose metabolism called GALACTOSEMIA, resulting in elevations of galactose in the blood.

D006027	Glycosides	Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
