What is an Anthrone test?
The Anthrone test is a chemical test used to detect the presence of carbohydrates, specifically monosaccharides and disaccharides, in a sample. It involves adding Anthrone reagent to a sample, which produces a blue color in the presence of carbohydrates. The intensity of the blue color can be used to estimate the concentration of carbohydrates in the sample.
What organic molecule does iodine test for?
They test for carbohydrates. The Iodine reagent tests for starch. The Benedict's reagent tests for small sugars. Most carbohydrates are are made of sugar, and starch is a type of carbohydrate.
What is the purpose of Molisch's test?
Molisch's Test (named after Austrian botanist Hans Molisch) is a sensitive chemical test for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid to produce an aldehyde, which condenses with two molecules of phenol (usually α-naphthol, though other phenols (e.g. resorcinol, thymol) also give colored products) resulting in a red- or purple-colored compound.
What group of compounds does starch belong to?
carbohydrates our of curiosity, do you have a test question to answer?
What does a positive Molisch's test on an unknown substance indicate?
A positive Molisch's test result indicates the presence of carbohydrates.

Substances which are ve to anthrone test?
The anthrone test, tests for carbohydrates. The positive indicator is glucose since glucose is one of the most common monosaccarides and is found in many polysaccarides. Anthrone tests positive for fructose, ribose, maltose, and sucrose.
What is the chemical basis of the Anthrone test?
The Anthrone test is based on the reaction between anthrone and carbohydrates, particularly simple sugars like glucose, to form a blue-green complex. The reaction occurs in acidic conditions and is commonly used to quantify the amount of sugars present in a sample.
Do glucose give a positive result for anthrone test?
Yes, glucose gives a positive result for the anthrone test. The anthrone reagent reacts with the carbohydrates present, including glucose, producing a blue-green color that can be detected spectrophotometrically.
Can you tell the concentration of protein in an anthrone test for carbohydrates without having the standard solution data and why?
i dont now
Why antrone is used for estimation of carbohydrates?
why anthrone is used for estimation of carbohydrates?
What is the procedure to prepare anthrone reagent?
To prepare anthrone reagent, dissolve 200 mg of anthrone in 100 ml of concentrated sulfuric acid. Mix the solution thoroughly and allow it to cool before use. Anthrone reagent is used for the detection of carbohydrates, specifically sugars, in various biological samples.
What is the general test used for carbohydrates?
i think the general test for carbohydrates is Molisch Test..
What is the chemical basis of molisch test?
basis of molisch testMolisch's Test is a sensitive chemical test for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid to produce an aldehyde, which condenses with two molecules of α-naphthol, though other phenols (e.g. resorcinol, thymol) also give colored products) resulting in a purple-colored compound (indicated by appearance of a purple ring at the interface between the acid and test layers).
Why albumin gives positive Molisch test?
Because it is a carbohydrates and molisch test will be positive in the presence of carbohydrates
What foods would test positive for carbohydrates?
Bread, pasta, and cereal would certainly "test positive" for carbohydrates.
What is the importance of Molisch's test performed on carbohydrates?
Molisch's Test is a chemical test for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid to produce an aldehyde. Its importance is that it tests the presence of carbohydrates based on their dehydration,
