全乙酰化的 N-叠氮乙酰半乳糖胺(Fully acetylated N-azidoacetylgalactosamine) 是一种功能化的半乳糖胺(Galactosamine)衍生物,具有叠氮基团(-N₃)和乙酰基(-COCH₃)保护基团。 结构与性质 叠氮基团(Azide, -N₃): 叠氮基团是一个高反应性的功能基团,能够与炔基(-C≡CH)进行点击化学反应,形成稳定的1,2...
GalNAc is a white crystalline powder that is soluble in water and ethanol. It has a molecular weight of 221.21 g/mol and a melting point of 208-210°C. GalNAc's chemical structure consists of a hexose sugar (galactose) and an amino group that is acetylated. GalNAc is stable under ordinar...
Finally, UDP-α--galactosamine was acetylated chemically with -acetoxysuccinimide. Product isolation was accomplished by anion-exchange chromatography and gel filtration. The overall yield was 34% and 82 mg were isolated.doi:info:doi/10.1016/S0008-6215(97)10077-5Bulter, T...

Finally, UDP-α-d-galactosamine was acetylated chemically with N-acetoxysuccinimide. Product isolation was accomplished by anion-exchange chromatography and gel filtration. The overall yield was 34% and 82 mg UDP-N-acetyl-α-d-galactosamine were isolated.Thomas...
Using an azide-labeled precursor to sialic acid, peracetylated N-azidoacetylmannosamine (Ac4ManNAz), we found that azide reactivity was present on highly purified RNA preparations from labeled cells. Although there was no precedent for a connection between sialoglycans and RNA, either direct or...
(GT7) proteins in the Carbohydrate-Active enZYmes database and are mainly distributed in invertebrates, unlike β1,4-GALTs, which are distributed in vertebrates. The other well-known GalNAcTs are UDP-N-acetyl-α-d-galactosamine:polypeptideN-acetylgalactosaminyltransferases (αppGalNAcTs), which ...
N-acetyl galactosamine GlcNAc/GluNAc: N-acetyl glucosamine HA: Hemagglutination kDa: Kilo Dalton Lac: Lactose LTLs: L-type lectins MALDI-TOF : Matrix assisted laser desorptional/Ionization-time of flight ManNAc : N-Acetyl mannosamine Meli: Melibiose mRNA : Messenger ribonucleic ac...
both N-acetylated and N-deacetylated. In a first preferred embodiment, the galactosaminogalactan polymer of the invention does not comprise any detectable N-deacetylated galactosamine. In that case, the N-acetylgalactosamine+galactosamine fraction corresponds solely to the N-acetylgalactosamine form. In ...
The number-average chain lengths of several preparations of teichuronic acid were estimated from the amounts of chromogen produced in comparison with the N-acetylated disaccharide. The values obtained are in good agreement with the weight-average molecular weight determined by ultracentrifugal analysis....
