What is a positive Sudan IV test result?
If no lipids are present, the red dye will sink to the bottom of the test tube. Sudan (iv) is not soluble in water but soluble in lipid.
What is the indicator for lipids?
Sudan red can be used to test for lipids. It is soluble in lipids so it will turn the entire sample red. Also, you can do the brown paper test. Put a few drops of the suspected lipid onto a brown paper bag. If the substance is a lipid, it will turn the spots translucent.
What is a negative resualt in eatting to many lipids?
Lipids are a type of fat which means that eating more lipids will result in more fat being stored. The breaking down of lipids may also be affected if you eat too much as you don't have an unlimited supply of lipase which is used to break down lipids.

Will hydrolysed dextrine give positive response to Benedict test?
Yes, it should. Benedicts test will be positive for reducing sugars, and since glucose is such a sugar, and would be a product of dextrin hydrolysis, you should get a positive result with Benedicts reagent.

What is the color of biruet solution?

When glycogen is added to benedicts reagent why would it remains blue?
Although glycogen is a carbohydrate, it is classified under POLYSACCHARIDES which are non-reducing sugars. Benedict's reagent is used to test for the presence of non-reducing sugars. The positive result for this is a brick-red precipitate or solution. It remained blue (which is negative) due to fact that ALL POLYSACCHARIDES (such as glycogen) ARE NON-REDUCING SUGARS > I'm a Nursing Student. >M.J.T.M.E.

What is the sign for multiplication and addition?
If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative. Multiplying a positive number by a negative number, or a negative number by a positive number, results in a negative result.For addition, if you add two positive numbers, the result is positive. If you add two negative numbers, the result is negative. If you add a positive and a negative number, the result depends on which of the numbers has the greater absolute value. For example, if the positive number has the greater absolute value (distance from zero), the result will be positive.If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative.
