Compendio degli studi più significativi con riferimento a proprietà, assunzione, effetti.

van Bastelaere P, Vangrysperre W, Kersters-Hilderson H. Kinetic studies of Mg(2+)-, Co(2+)- and Mn(2+)-activated D-xylose isomerases. Biochem J. 1991 Aug 15;278 ( Pt 1)(Pt 1):285-92.

Abstract. The kinetic parameters for the interconverting substrates D-xylose in equilibrium D-xylulose and D-glucose in equilibrium D-fructose were determined for several D-xylose isomerases, with Mg2+, Co2+ and Mn2+ as metal ion activators.

Campeol E, Flamini G, Cioni PL, Morelli I, D'Andrea F, Cremonini R. 1,5-Anhydroxylitol from leaves of Olea europaea. Carbohydr Res. 2004 Nov 15;339(16):2731-2. doi: 10.1016/j.carres.2004.09.001. 

Abstract. 1,5-Anhydroxylitol, a compound never found previously in the vegetal kingdom was obtained from Olea europaea leaves in approximately 0.5-1% yield.

Fletcher Jr, H. G., & Hudson, C. S. (1947). 1, 5-Anhydro-xylitol. Journal of the American Chemical Society, 69(4), 921-924.

Abstract. The purpose of the present investigation is to extend this apparently general synthetic method to the pentiol series.

Xia Q, Jin X, Zhang G, Liu M, Wang J, Li Y, Fang T, Ding J, Zhang D, Meng K, Chen X, Yang C. Catalytic Deoxygenation of Xylitol to Renewable Chemicals: Advances on Catalyst Design and Mechanistic Studies. Chem Rec. 2021 Jan;21(1):133-148. doi: 10.1002/tcr.202000101. 

Abstract. In this mini-review, we have critically discussed the conversion routes involved in xylitol deoxygenation over solid catalyst materials, the nanostructures of supported metal catalysts for C-H, C-C and C-O bond cleavage reactions, and mechanistic investigation for xylitol conversion.

Veerapen N, Taylor SA, Walsby CJ, Pinto BM. A mild Pummerer-like reaction of carbohydrate-based selenoethers and thioethers involving linear ozonide acetates as putative intermediates. J Am Chem Soc. 2006 Jan 11;128(1):227-39. doi: 10.1021/ja0557029. 

Abstract. The results of these experiments are consistent with the intermediacy of radical species and suggest a new and milder synthetic method to generate Pummerer-type products.

Mäkinen, K. K. (1978). Xylitol as a chemical compound. In Biochemical Principles of the Use of Xylitol in Medicine and Nutrition with Special Consideration of Dental Aspects (pp. 9-14). Birkhäuser, Basel.

Abstract. The crystalline xylitol prepared by Wolfrom and Kohn [3] in 1942 was a hygroscopic and metastable product with a melting point of 61–61.5 °C. The product was formed during prolonged standing of xylitol syrup in an ice box...
