The enzymatic synthesis of fructooligosaccharides (FOS) was carried out using a partially purified -fructofuranosidase from the commercial enzyme preparation Viscozyme L. Partial purification of -fructofuranosidase from Viscozyme L was done by batch adsorption using ion-exchange resin DEAESepharose, showing a 6-fold increase in specific activity.

Imidazolium-based ionic liquids are important solvents for the processing of natural cellulose. Little is known about their use in synthesizing cellulose via bottom-up polymerization of β-1,4-D-glucosyl chains in solution. Here, we analyzed cellodextrin phosphorylase-catalyzed synthesis of cello-oligosaccharides, and the subsequent spontaneous self-assembly of the chains, in the presence of cellulose-dissolving ionic liquid, 1,3-dimethylimidazolium dimethyl phosphate ([Dmim]DMP) or 1-ethyl-3-methylimidazolium acetate ([Emim]OAc).

Resistant starch type 3 (RS-3) holds great potential as a prebiotic by supporting gut microbiota following intestinal digestion. However the factors influencing the digestibility of RS-3 are largely unknown. This research aims to reveal how crystal type and molecular weight (distribution) of RS-3 influence its resistance.

Glycosides of 4-nitrocatechol (1,2-dihydroxy 4-nitrobenzene) with α-D-glucopyranose and α-D-mannopyranose were synthesized by the glycosylation of phenol with peracetylated sugars in the presence of BF3·OBu2 . The glycoside of 4-nitrocatechol with β -D-galactopyranose was prepared by the glycosylation of this phenol as sodium phenoxide with tetra-O-benzoyl-α-D-galactopyranosyl bromide.

Coordination compounds containing dicyanoargentate(I) have remarkable biological potential due to their therapeutic antibacterial, antifungal, antibiofilm, and anticancer properties. In this study, a new dicyanoargentate(I)- based complex was synthesized and characterized by various procedures (elemental, thermal, FT-IR for complex) involving crystal analysis of the complex. In addition, the biological activity of this new compound on the acetylcholinesterase (AChE) enzyme, an important enzyme for the nervous system, was investigated.

Plant induced defense against herbivory are generally associated with metabolic costs that result in the allocation of photosynthates from growth and reproduction to the synthesis of defense compounds. Therefore, it is essential that plants are capable of sensing and differentiating mechanical injury from herbivore injury.

In order to study some of its enzymatic properties, phosphatidylinositol synthase 1 (AtPIS1) from the plant Arabidopsis thaliana was expressed in Escherichia coli, a host naturally devoid of phosphatidylinositol (PtdIns). In the context of the bacterial membrane and in addition to de novo synthesis, the plant enzyme is capable of catalysing the exchange of the inositol polar head for another inositol. Our data clearly show that the CDP-diacylglycerol-independent exchange reaction can occur using endogenous PtdIns molecular species or PtdIns molecular species from soybean added exogenously....
