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 and amylopectin. Amylose is unbranched whereas amylopectin is branched. Structural polysaccharides consist of cellulose‚ which is a major component of plant cell

important in controlling reaction speed (by initiating and regulating biological activity)‚ cell communication‚ and growth. One particularly significant enzyme is amylase‚ which catalyzes the hydrolysis of alpha glycosidic linkages of amylose‚ starch components‚ and other oligosaccharides (Qian‚ et al.‚ 1994). Porcine pancreatic alpha-amylase can be found in pancreatic secretions‚ and works most efficiently at pH 6.9 for the majority of substrates. This ideal pH‚ however‚ has shown to shift

the effect of pH on amylase activity Aim The aim of the experiment is to determine the effects of different pH and the rate of reaction on fungal amylase and starch. Introduction The enzyme amylase is found in the human body‚ it catalyses the hydrolosis of internal glycosidic bonds in polysaccharides‚ the breakdown of starch into sugars. Amylase is present in human saliva‚ where it initiates the chemical process of digestion. Enzymes work best at an optimum pH of 7 which is the bodies

In the lab‚ three experiments were completed: the Iodine experiment‚ Benedict’s experiment and the Biuret experiment to test for starch and glycogen‚ reducing sugars and protein in the respective order. 12 solutions were given where 11 were known and the 12th was an unknown. The solutions that were supplied can be found in the results and observations section of this report. When completing such experiments‚ there are always controls used to make sure the procedure is followed and that no cross

How will changing the percentage of sodium chloride concentration affect the rate of reaction of enzyme amylase‚ measured using the absorbance of starch and iodine with a spectrophotometer. Introduction: Amylase is an enzyme that is involved in the human digestive process. Found in both the human pancreas and the human saliva‚ amylase breaks down starch into sugar so that large molecules can be easily digested1. Like all enzymes‚ amylase must be kept in a certain condition in order to function properly

In order to find the Vitamin C content you will need to use a process called titration which‚ according to the Columbia Electronic Encyclopedia‚ is when you add a chemicals to a liquid in order to create a reaction which can determine the content of a substance inside the liquid. This is how you will find the Vitamin C content of different juices. Iodine will be added to the juice‚ which will create a reaction that can help determine the Vitamin C content. To start‚ pour 30 milliliters (mL) of Lugol’s

Inventions have evolved and continue to evolve such that after several years of study‚ research and experimentation reach great developments. With continuing efforts to investigate the constituents of Philippine plants‚ we have pursued investigation of starch of the Water Hyacinth (Eichhornia Crassipes) as an alternative component for making a Biodegradable Plastic. Producing Bio-Plastic is a little bit advanced but it is one of the most popular projects‚ since we are advocating a greener world and a safety

Glucose and starch have bigger molecules‚ and therefore are less likely to pass through the dialysis tubing Materials: • 250- mL beaker • 12 test tubes (varied sizes) • 200mm dialysis tubing • String • 1.0% starch solution • 10% glucose solution • 5% sodium chloride solution • Benedict’s reagent • Iodine reagent o 0.1M silver nitrate solution (in a dropper
