This unit describes the fractionation and analysis of neutral oligosaccharides by high-performance liquid chromatography (HPLC) on bonded amine columns. Separation is based upon hydrogen bonding between the NH2 groups of the column and the hydroxyl groups of the oligosaccharides. A support protocol describes the reduction and desalting of neutral oligosaccharides with sodium borohydride.
Oligosaccharides have many isomers and MALDI-QIT-TOFMS(n) analysis is effective for determining their structures. However, it is difficult to elucidate in detail the structures of fucosylated and/or sialylated oligosaccharides that are known to be disease markers because fucose and sialic acid residues are easily released. We have introduced a technique of labeling oligosaccharides with a pyren...
Background Morinda officinalis oligosaccharides have been reported to exert neuroprotective and antidepressant-like effects in the forced swim test in mice. However, the mechanisms that underlie the antidepressant-like effects of Morinda officinalis oligosaccharides are unclear. Methods Chronic unpredictable stress and forced swim test were used to explore the antidepressant-like effects of M...
This study examines the genes coding for enzymes involved in bovine milk oligosaccharide metabolism by comparing the oligosaccharide profiles with the expressions of glycosylation-related genes. Fresh milk samples (n = 32) were collected from four Holstein and Jersey cows at days 1, 15, 90 and 250 of lactation and free milk oligosaccharide profiles were analyzed. RNA was extracted from milk som...
The carbohydrate binding properties of jacalin lectin were examined using RAF9 cell-derived D-[6-3H]glucosamine-radiolabeled total glycopeptides containing N-linked and O-linked oligosaccharides. The binding of N-linked glycopeptides to jacalin was abolished by treatment of alpha-galactosidase whereas O-linked glycopeptides were still bound lectin after this treatment. The removal of O-linked o...
Vine shoots are agricultural residues that can be used as a raw material in agro-biorefineries, which their main constituents individually converted into valuable bioproducts. The treatment of vine uncatalyzed media containing water and 1-butanol enabled the single-stage separation major different phases: aqueous phase from treatments contained hemicellulose-derived products (mainly form oligos...

To analyze the array of special literature and summarize information obtained on peculiarities prebiotics based mannan-oligosaccharides. review basic principles prospects their application in fish feeding, first all conditions aquaculture Ukraine. Findings. An overview modern scientific publications pecularitires mannan-oligosaccharides, prerequisites for widespread use is presented. T...
BACKGROUND Corn stover is lignocellulosic biomass that has potential to be used as raw material for bioethanol production. In the current research, dilute ammonia pretreatment was used to improve the accessibility of corn stover carbohydrates to subsequently added hydrolytic enzymes. Some carbohydrates, however, were still present after enzymatic hydrolysis and fermentation. Hence, this researc...
