Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following are termed as reducing sugars?
A
aldohexoses
B
trioses
C
ketohexoses
D
None of the above
Explanation: 

Detailed explanation-1: -The most common carbohydrate is glucose (C6H12O6). Applying the terms defined above, glucose is a monosaccharide, an aldohexose (note that the function and size classifications are combined in one word) and a reducing sugar.

Detailed explanation-2: -Those sugars which act as reducing agents are called reducing sugars. They contain an aldehyde (-CHO) are or a ketonic C = O all monosccharides and disaccharides (except sucrose) are reducing sugars, e.g., glucose, fructose, lactose etc.

Detailed explanation-3: -Aldoses and ketoses Monosaccharides which contain an aldehyde group are known as aldoses, and those with a ketone group are known as ketoses. The aldehyde can be oxidized via a redox reaction in which another compound is reduced. Thus, aldoses are reducing sugars.

Detailed explanation-4: -Glucose (also known as dextrose) is a carbohydrate compound consisting of six carbon atoms and an aldehyde group and they are referred to as aldohexose.
