“…These results suggested that the transfer product is a-monoglucoside of ( + )-catechin. Figure 4 shows 1 H -and 13C_ NMR spectra of the transfer product in acetone-d 6 • Results are summarized in Table II. In lH-NMR spectrum, proton signals would be assigned to the ( + )-catechin 26 ) and glucose moieties in comparison with those of standard (+ )-catechin and D-glucose.…”

“…The molecular weight was estimated from the m/z value of the quasimolecular ion (M + H) + peak. Proton nuclear resonance ctH-NMR) spectra (199.5 MHz) and carbon-13 nuclear resonance ct 3C_ NMR) spectra (50.10 MHz) of the sample in acetone-d 6 solution were recorded with a JEOL-FX200 spectrometer and tetramethylsilane as an internal standard.…”

“…Seven amylose samples with narrow molecular-weight distribution and no branching [19][20][21][22] were enzymatically synthesized by the previously reported method 19 using potato phosphorylase (EC 2.4.1.1.) or supplied by Ezaki Glico Co., Ltd. Their weight-average molecular weights M w ranged from 6 Â 10 3 to 1 Â 10 6 and their weight to number-average molecular weight ratios M w =M n were less than 1.2 when estimated by SEC-LS (size exclusion chromatography combined with multiangle or low-angle light scattering and refractometry).…”

“…Recently, an enzymesynthesizing method for amylose using sucrose phosphorylase (EC 2.4.1.7) and glucan phosphorylase (EC 2.4.1.1) was developed. [14][15][16] Complete linear amylose with a desirable molecular weight can be prepared by controlling the enzyme reaction strictly. Moreover, one of the advantages of synthesizing amylose enzymatically is that cheap sucrose and cellobiose are used as ingredients.…”
