TextSentencer_T1 0-117 Sentence denotes Structure determination of Cryptococcus neoformans serotype A-variant glucuronoxylomannan by 13C-n.m.r. spectroscopy.
TextSentencer_T2 118-405 Sentence denotes A series of polysaccharides was derived by physical and chemical methods from an antigenic, O-acetyl-containing, glucuronoxylomannan (GXM), isolated from the growth medium of Cryptococcus neoformans (CDC B2550) serotype A-variant having composition ratios of Man:Xyl:GlcA:OAc = 10:4:3:6.
TextSentencer_T3 406-481 Sentence denotes 13C-N.m.r. spectra of derivatives provided new structural evidence for GXM.
TextSentencer_T4 482-569 Sentence denotes Treatment of GXM with Li in ethylenediamine gave a xylomannan (XM, with Man:Xyl = 5:2).
TextSentencer_T5 570-612 Sentence denotes Smith degradation of XM gave a mannan (M).
TextSentencer_T6 613-667 Sentence denotes Ultrasonic treatment of GXM gave GXM-sonicated (GXMS).
TextSentencer_T7 668-856 Sentence denotes Treatment of GXM with 3-(3-dimethylaminopropyl)-1-ethylcarbodiimide.HCl and then with NaBH4 gave reduced GXMS (RGXMS), or with aq. trifluoroacetic acid gave partially acid-hydrolyzed GXMS.
TextSentencer_T8 857-950 Sentence denotes Periodate oxidation of GXM and NaBH4 reduction of the product gave a polyalcohol-mannan (PM).
TextSentencer_T9 951-1047 Sentence denotes Treatment of GXMS, RGXMS, and PM with NH4OH at pH 11 gave the respective O-deacetylated analogs.
TextSentencer_T10 1048-1185 Sentence denotes Comparison among the 13C-n.m.r. spectra of GXM, the various derivatives, and reference monosaccharides allowed the following conclusions:
TextSentencer_T11 1186-1393 Sentence denotes M is (1----3)-alpha-D-mannopyranan; XM consists of the M backbone with 91% of the Xyl on nonadjacent Man residues as 2-O-beta-D-Xylp substituents and with 9% as 4-O-D-Xylp substituents on other Man residues.
TextSentencer_T12 1394-1646 Sentence denotes GXM consists of the XM structure, but with non-D-xylosylated Man residues substituted with 2-O-beta-D-GlcpA substituents and with 6-O-acetyl groups distributed approximately equally on Man residues that have other substituents and those that have none.
TextSentencer_T13 1647-1790 Sentence denotes The molecular mechanics program MM2 was used to estimate the relative energies of anomeric orientations of the typical glycosidic linkage in M.
TextSentencer_T14 1791-2047 Sentence denotes The results suggest that 6'-OH----O-2 H-bonding is significant in the minimal-energy orientation of M, with phi = -36 degrees and psi = 51 degrees, and that two other glycosidic orientations may be important in the 2-O- or 6-O-substituted derivatives of M.
