With a molecular mass of 349.33 Da, the transfer product was identified as a glucosyl

These are independent adherence mechanisms, one mediated by PMN Fc receptors, the others by engagement of different glycoproteins and glycolipids, containing terminal sialic acids and N-acetylglucosamines (WGA binders) and mannosyl and glucosyl
groups in multivalent (ConA) as well as monovalent (SConA) interactions.
For the complete hydrolysis of cellulose into monomer glucose the synergistic action of all three cellulolytic enzymes including endo-[beta]-1,4-glucanase (EC 126.96.36.199, EG, randomly cleaving internal linkages), cellobiohydrolase (EC 188.8.131.52, CBH, specifically hydrolyzing cellobiosyl units from non-reducing ends), and [beta]-D-glucosidase (EC 184.108.40.206, hydrolyzing glucosyl
units from cellooligosaccharides) is required (Perez et al, 2002).
Two oleanane-type triterpenoids substituted with galloyl and glucosyl
moieties were identified for the first time, one of which exhibits sweet properties.
(1981) An efficient method for glucosylation of hydroxy compounds using glucosyl
The main chain is composed of two mannosyl and two galactosyl moieties; one branch contains one glucosyl
moiety and the other branch is composed of one galactosyl and one rhamnosyl moiety .
The position of the cinnamic ester group in the glucose unity was proved by long-range HMBC correlation between the ester carbonyl group and the glucosyl
hydrogen: [[delta].sub.C] 165.2 and H-2'[[delta].sub.H] 5.65, in compound 2, and [[delta].sub.C] 165.8 and H-2' [[delta].sub.H] 5.56, in compound 3.

The basis for these experiments is given by the well-established notion that hydrolysis of intragastrically administered starch is a prerequisite for the entrance of the derived glucosyl
units into blood.
Briefly, LGM2605 was synthesized from vanillin via secoisolariciresinol and a glucosyl
donor (perbenzoyl-protected trichloroacetimidate under the influence of TMSOTf) through a concise route that involved chromatographic separation of diastereomeric diglucoside derivatives.
