Sn-glycerol-3-phosphate accumulates during starch catabolism by intact isolated chloroplasts from Chlam ydom onas reinhardii in the dark. Further products detected mainly were 3-phosphoglyceric acid and triose phosphates with a ratio between 3-phosphoglyceric acid, sn-glycerol-3phosphate and triose phosphates of 1 .0 :0 .9 :0 .2 . The production of sn-glycerol-3-phosphate by a plastidic glycero...

We have investigated the hypoglycemic effect induced by the starch obtained from the unripe fruits of Solanum lycocarpum (Solanaceae). Per os administration of the starch (1000 or 2000 mg/kg, twice daily for 7 days, N = 6) did not change glycemia levels of nondiabetic female Swiss mice weighing 25-30 g. In streptozotocin-induced diabetic mice, similar treatment with the starch did not change th...

Conversion of Glucose to Ethanol In the U.S., corn is the predominant source of starch (glucose) used to produce ethanol. With the exception of sugar cane, corn provides the highest ethanol yields compared to any other feedstock being used (Table 2). However, research is underway to develop methods to convert carbohydrates from cellulosic feedstocks such as softwood (Arwa et al., 2005), non-sta...

Desirable grain quality attributes vary depending upon the intended end use of grain. Environment, production practices and genetics are all of importance. Nutritional value of grain is most important for animal feed. Dry mill and alkaline cooked products require hard kernels with low breakage susceptibility and high protein concentration. Grain for these uses would best be produced under dryla...

Short chain fatty acids (SCFAs) are the products of colonic bacterial degradation of unabsorbed starch and non-starch polysaccharide (fibre). They are important anions in the colonic lumen, affecting both colonocyte morphology and function. The three main acids (acetate, propionate, and butyrate) stimulate colonic sodium and fluid absorption and exert proliferative effects on the colonocyte. Ex...

In this manuscript, we describe the results of our recent studies on carbon aerogels derived from natural starches. A facile method for the fabrication of carbon aerogels is presented. Moreover, the complete analysis of the carbonization process of different starch aerogels (potato, maize, and rice) was performed using thermogravimetric studies combined with a detailed analysis of evolved decom...

Here, we report on near-infrared and ATR/FT-IR spectroscopic measurements of magnesium stearate and potato starch powder blends. In the pharmaceutical and food industries, magnesium stearate is commonly used as a supplement in powder blends or granules for the purpose of lubrication and to minimize aggregation and adherence. However, excessive blending of magnesium stearate (MgSt) may lead to u...
