Purification Methods
Crystallise D(+)-turanose from H2O by addition of EtOH (its solubility is 5.3% in 95% EtOH). Form m 157o is obtained by crystallisation from hot MeOH, and mutarotates from +27.3o to [] 20D +88o (c 4, H2O). The phenylosazone crystallises from 15 parts of 95% EtOH with m 200-205o, [] D 24.5o mutarotating to +33o[24hours, c 0.82, pyridine/EtOH (4:6)]. [Pascu Methods in Carbohydrate Chemistry I 353 1962, Academic Press, Beilstein 17/7 V 213.] In D2O at 36o 1H NMR showed the following ratios: -pyranose (<4), -pyranose (39), -furanose (20) and -furanose (41)[Angyal Adv Carbohydr Chem 42 15 1984].
Check Digit Verification of cas no
The CAS Registry Mumber 547-25-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 547-25:
(5*5)+(4*4)+(3*7)+(2*2)+(1*5)=71
71 % 10 = 1
So 547-25-1 is a valid CAS Registry Number.

Production and characterization of low-calorie turanose and digestion-resistant starch by an amylosucrase from Neisseria subflava
Park, Min-Oh,Chandrasekaran, Murugesan,Yoo, Sang-Ho
, (2019)
This study was intended to produce turanose and resistant starch (RS) using recombinant amylosucrase from Neisseria subflava (NsAS). Turanose production yield maximally reached to 76% of sucrose substrate at 40 °C by NsAS treatment. To evaluate turanose as a low-calorie functional sweetener, its hydrolysis pattern was investigated in continuous artificial digestion system. When turanose was consecutively exposed through small intestinal phase, only 8% of disaccharide was hydrolyzed. Structural modification of gelatinized corn or rice starch was carried out by NsAS with sucrose as a glucosyl donor. Non-digestibility of enzyme-modified starches increased to 47.3% maximally through branch-chain elongation, enough for chain-chain association and recrystallization. Obviously, NsAS-modified starches had higher gelatinization peak temperatures than native counterparts, and their paste viscosity was inversely related to their digestibility due to elongated-chain induced retrogradation. These results suggested that NsAS could be a vital biocatalyst candidate in food industry to produce next generation low-calorie carbohydrate food materials.
