Poly , glycosylated

Other compounds identified in caramels are di-D-fructose and poly(glycosyl) dianhydrides (DFAs). DFAs were found in caramels prepared from D-fructose, D-glucose, and sucrose. The analysis was done after derivatization as TMS (per-0-trimethylsilyl) derivatives or as TMS-oxime (per-O-trimethylsilyl oxime) by... 

Glycosphingolipids can also be grouped according to the number of carbohydrate residues, such as mono-, di-, tri-, tetra-, penta-, to poly-glycosyl ceramide.The structures of all major basic types of glycolipids and the main sources of glycosphingolipids are listed in Table 1.

The cell walls of most Gram-positive bacteria contain (1 ->3) poly(glycerol phosphate) teichoic acids which can bear D-alanyl or glycosyl substituents.56 However, the cell walls of Bacillus stearothermophilus B65 contain a glycerol teichoic acid which is free of substituents.57 This is contrary to evidence that had been obtained from biosynthetic studies.58... 

Molecular weight Glycosyl sequence in oligo- and poly-saccharides... 

Especially noteworthy are the methods for determining the sequence of glycosyl residues in a complex oligo- or poly-saccharide. Methods of this type generate a series of overlapping oligomers that are separated and identified by l.c., in conjunction with either direct or indirect mass spectrometry. Most of these methods are still in the developmental stages, and they often require expensive and not-routinely available equipment (see also. Section IV,2) (see Addendum). 

In earlier investigations, it had been recognized335,536 that interferon retains full biological activity after removal of sialic acid, or after removal of 50% of the total carbohydrate.532 However, its apparent hy-drophobicity, and affinity for poly(ribonucleotides), are conferred only when glycosylation is unimpaired.337...
