ConditionsYieldWith Biolacta N5 In N,N-dimethylhexanamide at 30℃; pH=5; aq. buffer; Enzymatic reaction; regioselective reaction;Experimental Procedure4.5. General procedure for transglycosylation reactions using glycoconjugatesGeneral procedure: A solution of 51.2 mg (0.17 M) p-nitrophenyl-β-d-galactopyranoside (donor) and 188 mg (0.85 M) of N-acetylglucosamine (acceptor) in 1 mL of green solvent (2 M)-buffer mixture was pre-equilibrated to 30 °C. Afterwards, 155 μmol/min (U) of β-galactosidase were added to the reaction mixture. Reaction was monitored by HPLC UV-vis and final products analysed by HPLC with an evaporative light scattering detector (ELSD). The reaction was stopped by heating the sample at 100 °C for 5 min.Isolation of disaccharides was done by carbon/Celite (50% m/m), chromatography, the column was eluted with milliQ water and ethanol gradient (from 5% to 15% v/v). and The structures of the disaccharides (Gal-β(1→4)GlcNAc and Gal-β(1→6)GlcNAc) were assigned by 1H and 13C NMR (D2O, 700 MHz), spectra were identical to previous references. , and In order to determine the effect of non-proteic substances present in Biolacta preparation in the reaction yield, transglycosylation reactions were carried out using semipurified (lyophilized) enzyme. The best performing solvents were chosen in view of the previous results, using crude extracts and setting the reactions with semipurified enzymes. The transglycosylation conditions were the same mentioned above and the reaction was monitored using HPLC-ELSD.For functionalized disaccharides the same protocol previously described was used, and different glycoconjugates as acceptors were added. A solution of 51.2 mg (0.17 M) pNP-β-Gal (donor) and the different monosaccharides functionalized 1 and 2 (0.51 M).86%With triethyl phosphate; sodium acetate; β-galactosidase In water at 30℃; galactosylation; Enzymatic reaction;

Use PatternN-Acetylglucosamine is a versatile ingredient widely used in pharmaceuticals, cosmetics, health supplements, and biomedical materials. Its primary sources include animal extraction and microbial fermentation.In the pharmaceutical field, it helps improve joint health, promotes cartilage matrix synthesis by chondrocytes, enhances cartilage repair, and alleviates joint pain. As a derivative of glucosamine, it supports skin health and tissue repair.In cosmetics, it stimulates the synthesis of hyaluronic acid (HA), enhancing skin hydration. It also repairs the skin barrier, reducing redness and sensitivity, while accelerating epidermal cell renewal and promoting wound healing. https://www.chemwhat.com/n-acetyl-glucosamine-cas-7512-17-6/
