Micromanipulative Studies on Gelatinized Starch Granules.
Gelatinized starch granules are generally considered to be comprised of sacs or outer membranes of starchy material enclosing a more or less fluid colloidal starch dispersion [see reviews by RADLEY (10)] and KERR (6). NXGEI, (9) and MEYER (8) considered the membrane to be precxistent in the native, ungelatinized granule. ALSBERG (1) and BADENHUIZEN (2, 3) on the other hand, concluded that the m...
متن کاملStarch phosphorylase inhibitor from sweet potato.
A protein, starch phosphorylase inhibitor, was purified from the root of sweet potato (Ipomoea batatas [L.] Lam. cv Tainon 65). It had a molecular weight of 250,000 and could be composed of five identical subunits. The isoelectric point of the inhibitor was 4.63. It was a noncompetitive inhibitor toward the sweet potato enzyme with a K(i) value of 1.3 x 10(-6) molar when glucose-1-P was the var...
متن کاملCharacterization of Digestion Resistance Sweet Potato Starch Phosphodiester
Purpose: To analyze the physicochemical properties and in vitro digestibility of sweet potato starch phosphodiester prepared using sodium trimetaphosphate. Methods: The physicochemical properties of sweet potato starch phosphodiester were analyzed by using infrared spectrometry (IR), differential scanning calorimetry (DSC) and rapid visco-analyser (RVA). In addition, an in vitro digestibility m...
متن کاملThe gene structure of starch phosphorylase from sweet potato.
a-Glucan phosphorylases are of key importance among the enzymes controlling the entry of storage polysaccharides into the glycolytic pathway in microbes, animals, and plants. The enzymes catalyze the reversible phosphorolysis of cu-l,4-glucosidic linkages in glucan substrates. Among SP from higher plants, those from potato are best studied. They are classified into L and H types depending on th...
متن کاملEvaluation of conditioning time and temperature on gelatinized starch and vitamin retention in a pelleted swine diet.
Two key feed processing parameters, conditioning temperature and time, were altered to determine their effects on concentration of gelatinized starch and vitamin retention in a pelleted finishing swine diet. Diet formulation (corn–soybean meal based with 30% distillers dried grains with solubles) was held constant. Treatments were arranged in a 2 × 3 factorial design plus a control with 2 condi...
