Vitamins in germination. Determination of free and combined inositol in germinating oats

“…Removal as BaSO4 involved losses by adsorption of inositol on the precipitate. Although Gregory (1935), using a much less sensitive method of estimation, stated that inositol was not adsorbed by barium sulphate under acid conditions, Needham (1923) and Bartow & Walker (1938) reported difficulties due to adsorption on insoluble precipitates. Sulphuric acid was found to be less effective than HCl at all concentrations except 0-5N for the same heating period.…”

“…The literature offers a wide choice of conditions for the liberation of inositol from phytin, whether by chemical (Bartow & Walker, 1938) or enzymic means (Peers, 1953). We believe that the sealed.…”

On the Structure of Galactinol

“…2 The latter form, which may represent as much as 90% of the total, has a varied composition, although the phosphate esters are certainly a major component. 3 The bound form may be freed completely by strong acid hydrolysis, and partly by the action of phosphatases and glycosidases. Structural studies on inositol containing phosphatides indicate that the myoinositol is chemically fixed in these substances through glycosidic bonds, phosphate ester links, and possibly esterification with carboxylic acids.4• 6 Brown and Serró6 have recently described a glycoside of myoinositol which they found to occur free in the juice of the sugar beet, and which they isolated in a pure crystalline form.…”
