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 and amylopectin. Amylose is unbranched whereas amylopectin is branched. Structural polysaccharides consist of cellulose‚ which is a major component of plant cell walls; chitin‚ which is a tough outer covering of invertebrates;

Rivaroxaban and Dabigatran are direct inhibitors of factor IIa (thrombin) and factor Xa (FXa) respectively. These drugs are under intense investigation in clinical trials and appear very promising. Heparin Unfractionated heparin (UFH) is a polysaccharide composed of between 10 and 100 saccharide units ((Hoffbrand 2004)). It inhibits all serine proteases to various extents but its main effect is inhibition of thrombin (IIa) and factor Xa (FXa) for which it requires antithrombin (AT) as a cofactor

LAB 10: NAME: DaeNia La Rodé DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without

to confer very high viscosities when in aqueous solution‚ and is described as a complex‚ highly branched‚ heterogeneous hydrophilic polysaccharide. The molecular weight of a typical gum has been reported to be about 840 kDa‚ calculated by Svedberg’s method and formula. Gum tragacanth is a heterogeneous and acidic polysaccharide and is a mixture of two polysaccharides‚ of which the water-soluble component is called tragacanthinl and the acidic water swellable component is called bassorin.

made up of carbon‚ hydrogen‚ and oxygen and are produced by green plants in the process of undergoing photosynthesis. A carbohydrate can be broken down into four different chemical groups: monosaccharides‚ disaccharides‚ oligosaccharides‚ and polysaccharides. Monosaccahrides are the simplest form of the carbohydrate. Monosaccharides are important fuel molecules as well as building blocks for nucleic acids. A monosaccharide is similar to a DNA

mechanical and biochemical reasons‚ though the exact reasons remain unclear. Molecules of carbohydrates and fats consist of carbon‚ hydrogen‚ and oxygen atoms. Carbohydrates range from simple monosaccharides (glucose‚ fructose‚ galactose) to complex polysaccharides (starch). Fats are triglycerides‚ made of assorted fatty acid monomers bound to glycerolbackbone. Some fatty acids‚ but not all‚ are essential in the diet: they cannot be synthesized in the body. Protein molecules contain nitrogen atoms in addition

usage A blood agar plate used to culture bacteria and diagnose infection. Agar or agar-agar is a gelatinous substance derived by boiling[1] a polysaccharide in red algae‚ where it accumulates in the cell walls of agarophyte and serves as the primary structural support for the algae’s cell walls.[2][3] Agar is a mixture of two components: the linear polysaccharide agarose‚ and a heterogeneous mixture of smaller molecules called agaropectin. Throughout history into modern times‚ agar has been chiefly used
