Sentence |
denotes |
Assignment of anomeric configurations of pyranose sugars in oligosaccharides using a sensitive FAB-MS strategy. |
TextSentencer_T2 |
112-293 |
Sentence |
denotes |
This paper describes a sensitive strategy employing fast atom bombardment mass spectrometry (FAB-MS) for defining the anomeric configurations of pyranose sugars in oligosaccharides. |
TextSentencer_T3 |
294-493 |
Sentence |
denotes |
The method, which is applicable to mixtures of reduced or unreduced oligosaccharides, is based upon FAB-MS analyses of deuteroacetylated derivatives before and after oxidation with chromium trioxide. |
TextSentencer_T4 |
494-730 |
Sentence |
denotes |
This reagent, whose potential value in carbohydrate chemistry was first recognized by Angyal and which was subsequently more fully exploited by Lindberg, oxidizes beta-pyranosides to keto-esters leaving alpha-pyranosides largely intact. |
TextSentencer_T5 |
731-867 |
Sentence |
denotes |
In this paper we show that the products of chromium trioxide oxidation can be successfully analysed at the microgram level using FAB-MS. |
TextSentencer_T6 |
868-1002 |
Sentence |
denotes |
The molecular and fragment ions produced in the FAB experiment define the number of sites oxidized and their location in the sequence. |
TextSentencer_T7 |
1003-1172 |
Sentence |
denotes |
For samples which fragment poorly we describe a mild methanolysis procedure, compatible with FAB-MS, which preferentially cleaves the esters formed during the oxidation. |
TextSentencer_T8 |
1173-1264 |
Sentence |
denotes |
Incorporation of an acetolysis step prior to oxidation permits analyses of polysaccharides. |
TextSentencer_T9 |
1265-1492 |
Sentence |
denotes |
This oxidation/FAB-MS strategy should prove valuable in structural analyses of a wide range of biologically important carbohydrates which cannot be isolated in sufficient quantities to permit nuclear magnetic resonance studies. |
