Concept explainers
a.
To explain:
Whether the carbohydrate D-glucose will produce a positive Benedict’s test or not.
Introduction:
Carbohydrate can be defined as “polyhydroxy
b.
To explain:
Whether the carbohydrate lactose will produce a positive Benedict’s test or not.
Introduction:
Carbohydrate can be defined as “polyhydroxy ketones” or “polyhydroxy aldehydes” or compounds which produce them on hydrolysis. On the basis of reactivity of carbohydrates, they can be classified as reducing and non-reducing sugar. Reducing sugars are those sugars in which free aldehyde or ketone group is present, which react with certain chemicals to reduce them. Non-reducing sugars lack free carbonyl group.
c.
To explain:
Whether the carbohydrate sucrose will produce a positive Benedict’s test or not.
