Yes .
Starch is made up of repeating glucose units. Though it is a non reducing sugar, its hydrolysis gives out pure glucose, which is known as dextrose. And glucose, as we know, is a reducing sugar and hence would give a positive result in Benedict's test.
No because glucose does not consist of two or more peptide bonds
Sucrose is formed from glucose and fructose.Sucrose is formed from glucose and fructose. Glucose and fructose gives positive test for benedict becuz both of them are reducing sugars whereas sucrose is not a reducing sugar so it gives negative test for benedict. On prolonged heating,sucrose will form glucose and fructose (reducing sugars)which ultimately gives a positive result .
It is positive for the metabolizing of glucose.

A pink color must be obtained.

The Benedict test will return a positive value for any reducing sugar. It will work with fructose, for example. Benedict solution oxidizes all the reducing sugars such as glucose, galactose and fructose. This implies that a positive result of Benedict's test can be any of the reducing sugars, not necessarily glucose. It will oxidize the carbonyl (which present in all type of sugar classes). So if we get a positive result in the Benedict test, it is not necessarily glucose; it could be galactose or fructose that also a reducing sugar. So Benedict test can't be used to assure glucose.
bluish color if pentose is present.
The test is positive for reducing sugars(Glucose). Green brown ppt with traces of red was formed when Fheling's solution was added to the spatula's measure of glucose in 1cm3 of water
yes a line is a line,I'd say it's positive
1% of glucose- no color changes 1% sucrose-no color changes 1% xyxlose-black 1%starch-light white 1%lactose-black
