4 Carbohydrates
نویسنده
چکیده
Carbohydrates are the major source of energy in diets fed to dairy cattle and usually comprise 60 to 70 percent of the total diet. The main function of carbohydrates is to provide energy for rumen microbes and the host animal. A secondary, but essential, function of certain types of carbohydrates is to maintain the health of the gastrointestinal tract. The carbohydrate fraction of feeds is a complex mixture of numerous monomers and polymers that are usually defined according to analytic procedures and availability to the animal. Carbohydrates are broadly classified as either nonstructural or structural. Nonstructural carbohydrates (NSC) are found inside the cells of plants and are usually more digestible than structural carbohydrates that are found in plant cell walls.

Effects of Lowering Glycemic Index of Dietary Carbohydrate on Plasma Uric Acid Levels: The OmniCarb Randomized Clinical Trial.
OBJECTIVE The effects of carbohydrates on plasma uric acid levels are a subject of controversy. We determined the individual and combined effects of carbohydrate quality (the glycemic index) and quantity (the proportion of total daily energy [percentage of carbohydrates]) on uric acid levels. METHODS We conducted a randomized, crossover trial of 4 different diets in overweight or obese adults...
متن کاملRecognition properties of receptors consisting of imidazole and indole recognition units towards carbohydrates
Compounds 4 and 5, including both 4(5)-substituted imidazole or 3-substituted indole units as the entities used in nature, and 2-aminopyridine group as a heterocyclic analogue of the asparagine/glutamine primary amide side chain, were prepared and their binding properties towards carbohydrates were studied. The design of these receptors was inspired by the binding motifs observed in the crystal...
متن کاملEffects of simple and complex carbohydrates on serum lipids and atherosclerosis in nonhuman primates.
Several studies on human beings have suggested that lipid metabolism (1-4) and the mortality rate from atherosclerotic heart disease (5) are related to the chemical nature of available carbohydrates in the diet. These studies showed the serum levels of cholesterol and triglyceride to be increased by dietary sucrose and decreased by complex carbohydrates such as dextrin. Other investigators, how...
متن کاملRelationship between dietary carbohydrates and fats in their influence on serum lipid concentrations.
1. Diets containing 45% joules as fat, 45% joules as carbohydrate and 10% joules as calcium caseinate were given for 5 days to ten men and seven women. The fats used were sunflower seed oil or cream, and the carbohydrates were either glucose and fructose, glucose and raw starch or fructose and raw starch. 2. Sunflower seed oil in the diet resulted, after 5 days, in a significant fall in the con...
متن کاملChanges in the respiratory quotient during surgery with or without carbohydrate loading.
Usually glucose is used as an energy source intraoperatively, and recently maltose containing fluids was introduced as intraoperative fluid supply. However, the optimal dosage and form of intraoperative carbohydrate have not yet been known. The authors compared changes in the RQ during surgery without any energy source supply, and with administration of glucose or maltose in twenty eight males ...
