Iodine is a test for starch while Benedict’s solution is a test for reducing sugars. When solution A is tested by benidicts test‚ the clear blue solution changed to a little reddish and brick red precipitate is formed.this result show that solution A is a reducing sugar. When carried out iodine test with solution A‚ the colourless solution remain unchanged . this tell us that starch is absent is solution A. When solution B is tested with Benedicts test‚ the clear blue solution remain unchanged‚ we

cysts can profoundly enlarge the kidneys while replacing much of the normal structure‚ resulting in reduced kidney function and leading to kidney failure. When PKD causes kidneys to fail-which usually happens after many years-the patient requires dialysis or kidney transplantation. About one-half of people with the most common type of PKD progress to kidney failure‚ also called

aim of this experiment is to investigate the affect of pH on the enzyme amylase. The amylase is used to break down the polysaccharide starch. Amylase is a digestive enzyme classified as a saccharidase (an enzyme that cleaves polysaccharides). It is mainly a constituent of pancreatic juice and saliva‚ needed for the breakdown of long-chain carbohydrates (such as starch) into smaller units. Amylase is also synthesized in the fruit of many plants during ripening‚ causing them to become sweeter‚ and also

them is the amylase enzyme. Amylases are found in saliva‚ and pancreatic secretions of the small intestine. The function of amylase is to break down big molecules of starch into small molecules like glucose; this process is called hydrolysis. Enzymes are very specific; for example‚ amylase is the only enzyme that will break down starch. It is similar to the theory of the lock and the key. The enzyme is the lock and the key is the substrate; only the correct key could fit into the keyhole of the lock

Amylase. Solutions of starch and amylase were held at selected temperatures by various methods of temperature control. Once the solutions reached and maintained the desired temperature they were combined. Samples at timed intervals were then taken and reacted with a reagent to determine the effect the selected temperatures had on the reaction rate of enzyme and substrate. Results indicated that the enzyme functions efficiently at its optimum temperature (50oC) digesting the starch present and that any

Treatment usually means hospital stay‚ because there needs to be a balance in the amount of fluids in the blood and medications to control blood potassium. Dialysis will need to take place in order to remove toxins from the blood. Until her kidneys recover‚ she will need to control her diet so her kidneys do not have to filter too much or work to hard.

Diabetes mellitus‚ or simply diabetes‚ is a group of metabolic diseases in which a person has high blood sugar‚ either because the pancreas does not produce enough insulin‚ or because cells do not respond to the insulin that is produced.[2] This high blood sugar produces the classical symptoms of polyuria (frequent urination)‚ polydipsia (increased thirst) and polyphagia (increased hunger). There are three main types of diabetes mellitus (DM). Type 1 DM results from the body’s failure to produce

Free Enzyme Starch Amylase
Introduction Starch is composed of α-amylose and amylopectin. The structure of α-amylose consists of long polymer chains of glucose units connected by an α (1-4) linkage. Amylopectin consists mainly of α (1-4) linked glucose residues but is a branched molecule with α (1-6) branch points every 24 to 30 glucose residues on average. As a result of the bond angles in the α (1-4) linkage‚ amylose actually forms a spiral much like a coiled spring. Amylose is responsible for the formation of a deep blue

by adding Benedict’s solution and heating it‚ there would be a color change if a reducing sugar is present‚ or it will remain blue (no reducing sugar). The objective of the Starch test was to test for starch in substances by using Iodine. The iodine will cause a substance to turn to a dark blue color if it is positive for starch. The objective for the Grease Spot Test was to test if the substance had a lipid. A positive reaction would make a translucent grease mark on a brown paper bag. The objective
