Spin-probe EPR study of some sugars in connection with desiccation tolerance of biological objects was written by Dzuba, S.A.;Golovina, Ye.A.;Tsvetkov, Yu.D.. And the article was included in Applied Magnetic Resonance in 1993.Category: tetrahydropyran This article mentions the following:
EPR spectra of the nitroxide radical Tempone introduced in trehalose, sucrose, glucose and in sucrose-raffinose and sucrose-glucose mixtures have been studied at different temperatures above the room temperature The sugars similar to those found in desiccation tolerant biol. organisms (trehalose, sucrose-raffinose mixture) are distinguished from the others by the stability of their phase state and by lower values of the effective activation energies for rotational mol. motion. Probably these properties are important for the mechanism by which sugars act to protect the cell during desiccation. In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7Category: tetrahydropyran).
(2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7) belongs to tetrahydropyran derivatives. Tetrahydropyrans are useful synthons for biologically important compounds. The Prins reaction of homoallylic alcohols with aldehydes afforded an alternative method for the preparation of tetrahydropyrans.Category: tetrahydropyran
