Free fatty acids are the major fuels for the myocardium, but during a higher load carbohydrates are preferred. Previously, we demonstrated that myocardial net lactate uptake was higher in lambs with aortopulmonary shunts than in control lambs. To determine whether this was caused by an increased lactate uptake and oxidation or by a decreased lactate release, we studied myocardial lactate and gl...

High-fibre diets offer several beneficial health effects. The objective of the present study was to investigate whether replacement of 30 % of the available carbohydrates with polydextrose (PDX) or soluble maize fibre (SCF) at breakfast and lunch would result in an increased fat oxidation rate and satiety, which may be of relevance for body weight control and diabetes prevention. In a single-bl...

Extrusion cooking, as a multi-step, multi-functional and thermal/mechanical process, has permitted a large number of food applications. Effects of extrusion cooking on nutritional quality are ambiguous. Beneficial effects include destruction of antinutritional factors, gelatinisation of starch, increased soluble dietary fibre and reduction of lipid oxidation. On the other hand, Maillard reactio...

The effects of glucose and lactate infusion on palmitate oxidation were compared with the effect of 2-tetradecylg]ycidic acid (TDGA), an irreversible inhibitor of the carnitine acyltransferase I, in nonmoxic canine myocardium. The initial capillary transit retention fraction of [l-"C]palmitate and its fractional distribution between oxidation and esterification in myocardium were measured by th...

The effects of glucose and lactate infusion on palmitate oxidation were compared with the effect of 2-tetradecylglycidic acid (TDGA), an irreversible inhibitor of the carnitine acyltransferase I, in normoxic canine myocardium. The initial capillary transit retention fraction of [1-11C]palmitate and its fractional distribution between oxidation and esterification in myocardium were measured by t...

Biochemical and physical changes of two types of fresh-cut fruits packaged in plastic containers and stocked at 4°C were studied over a period of six days. The first type of container was film-lidded and contained orange juice, pomelo, kiwifruit and orange slices. The second type was plastic-lidded and contained orange juice, apple, kiwifruit and orange slices. Color, vitamin C and carbohydrate...

-1. Patterns of fuel utilization in the thoracic muscles of three species of ants have been established. 2. The thoracic muscles of Formica ulkei exhibit a typical Hymenopteran metabolic organization, relying exclusively upon carbohydrate oxidation for the provision of metabolic energy. This species feeds upon honeydew. 3. Pooonomyrmex californicus, a granivorous ant, exhibits a metabofic organ...

The inhibitory effects of a number of periodate-oxidation products of carbohydrates and carbohydrate derivatives were studied on various transplanted tumors in mice and on a variety of microorganisms. Many of the compounds showed striking inhibition of Ehrlich ascites and inhibition of Leukemia L1210 in mice. The compounds were not active against Sarcoma 180 and Adenocarcinoma 755 or against an...

Gluconobacter oxydans is characterized by its ability to incompletely oxidize carbohydrates and alcohols. The high yields of its oxidation products and complete secretion into the medium make it important for industrial use. We report the finished genome sequence of Gluconobacter oxydans H24, an industrial strain with high l-sorbose productivity.
