elements of carbon‚ oxygen and hydrogen. (Lea‚ 2002) The simplest carbohydrate molecule is known as a monosaccharide‚ which is a simple sugar. Monosaccharide’s can be joined together by a covalent glycosidic bond to create more complex sugars such as disaccharides (2 monosaccharide’s)‚ oligosaccharides (between three to ten monosaccharide’s) and polysaccharides (consists of several monosaccharide’s). (Karp‚ 2010) Starch is the most common nutritional polysaccharide‚ which consists of two polymers: amylose

The study will focus on the use of Ipil-ipil (Leucaena leucocephala)‚ a common plant use as perimeter barricade; and honey‚ disaccharide from bees. This study aims to establish the efficacy of the resulting concoction in reducing if not totally eradicating parasites in children. The objective of regular deworming is to get rid of existing infections or to lower worm burden.

consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast in 2 steps: first sucrose (a disaccharide whose structure is in your textbook) is broken down to two monosaccharides‚ glucose and fructose. These monosaccharides are then converted into ethanol and carbon dioxide. * Materials 250-mL Erlenmeyer flask 250-mL Beaker Bruchner funnel

Carbon‚ Hydrogen and Oxygen. These three simple elements make up one of the most useful substances for many living organisms: Carbohydrates. Carbohydrates are used for numerous processes in organisms from acting in important roles of cellular recognition in the human body to storing chemical energy in plants in the form or starch. The roles of carbohydrates in the human body alone are numerous; providing energy for working muscles‚ providing energy for the regulation of blood glucose‚ preventing

and how we can avoid it. Body: I. Sugar is the simple name for the sweet‚ short-chained‚ simple carbohydrate used in foods. Sugar is broken down into two categories; simple monosaccharides such as glucose‚ fructose‚ and galactose‚ and complex disaccharides such as sucrose‚ maltose‚ and lactose. a. Sugar is a very calorie dense food with no nutritional value. Not all calories act the same way‚ calories from sugar are more fattening than any other calorie.
