Questions & Answers

Q: What are carbohydrates?

Carbohydrates are optically active polyhydroxy aldehydes or polyhydroxy ketones that can be hydrolyzed to form polyhydroxy aldehydes or polyhydroxy ketones.

Q: How are carbohydrates classified?

Carbohydrates are classified into two types: simple and complex carbohydrates. Simple carbohydrates are further divided into aldoses and ketoses, while complex carbohydrates are divided into oligosaccharides and polysaccharides.

Q: What is the difference between aldoses and ketoses?

Aldoses are monosaccharides containing an aldehyde functional group, while ketoses are monosaccharides containing a ketone functional group.

Q: What are the examples of complex carbohydrates?

Examples of complex carbohydrates include starch and cellulose, which can be hydrolyzed to produce a large number of monosaccharides.
