Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper (II) sulfate pentahydrate. [ 1 ] It is often used in place of Fehling's solution to detect the presence of reducing sugars and other reducing substances. [ 2 ]
Blue bottle reaction video. The blue bottle experiment is a color-changing redox chemical reaction. An aqueous solution containing glucose, sodium hydroxide, methylene blue is prepared in a closed bottle containing some air. Upon standing, it spontaneously turns from blue to colorless due to reduction of methylene blue by the alkaline glucose ...
The glucose oxidase enzyme (GOx or GOD) also known as notatin (EC number 1.1.3.4) is an oxidoreductase that catalyses the oxidation of glucose to hydrogen peroxide and D-glucono-δ-lactone. This enzyme is produced by certain species of fungi and insects and displays antibacterial activity when oxygen and glucose are present.
Hyperosmolar hyperglycemic state (HHS), also known as hyperosmolar non-ketotic state (HONK), is a complication of diabetes mellitus in which high blood sugar results in high osmolarity without significant ketoacidosis. [4] [5] Symptoms include signs of dehydration, weakness, leg cramps, vision problems, and an altered level of consciousness. [2]
Monosaccharides. In organic chemistry, Fehling's solution is a chemical reagent used to differentiate between water-soluble carbohydrate and ketone (>C=O) functional groups, and as a test for reducing sugars and non-reducing sugars, supplementary to the Tollens' reagent test. The test was developed by German chemist Hermann von Fehling in 1849.
Blood glucose monitoring is the use of a glucose meter for testing the concentration of glucose in the blood (glycemia). Particularly important in diabetes management, a blood glucose test is typically performed by piercing the skin (typically, via fingerstick) to draw blood, then applying the blood to a chemically active disposable 'test-strip'.
The glucose tolerance test (GTT, not to be confused with GGT test) is a medical test in which glucose is given and blood samples taken afterward to determine how quickly it is cleared from the blood. [ 1 ] The test is usually used to test for diabetes, insulin resistance, impaired beta cell function, [ 2 ] and sometimes reactive hypoglycemia ...
Type 2 diabetes makes up about 90% of cases of diabetes, with the other 10% due primarily to type 1 diabetesand gestational diabetes.[1] In type 1 diabetes, there is a lower total level of insulinto control blood glucose, due to an autoimmune-induced loss of insulin-producing beta cellsin the pancreas. [12][13]Diagnosis of diabetes is by blood ...
