Metabolic Studies on Intermediates in the myo-Inositol Oxidation Pathway in Lilium longiflorum Pollen: III. Polysaccharidic Origin of Labeled Glucose

Metabolic Studies on Intermediates in the myo-Inositol Oxidation Pathway in Lilium longiflorum Pollen: III. Polysaccharidic Origin of Labeled Glucose

On the basis of solubility, hydrolysis by glucoamylase (EC 3.2.1.3), and monomeric composition, starch appears to be the major glucose-containing, hot water-soluble polysaccharide that is labeled when germinated lily (Lilium longiflorum Thunb., cv. Ace) pollen is grown in the presence of myo-[2-3H]i...

Zusammenfassung:On the basis of solubility, hydrolysis by glucoamylase (EC 3.2.1.3), and monomeric composition, starch appears to be the major glucose-containing, hot water-soluble polysaccharide that is labeled when germinated lily (Lilium longiflorum Thunb., cv. Ace) pollen is grown in the presence of myo-[2-3H]inositol, D-[R5,S5-3H]xylose, or L-[1-14C]arabinose.
