Concept introduction:

Carbohydrate- Carbohydrates are the naturally occurring organic compound. It consists of carbon, hydrogen, and oxygen. There are aldehyde, ketone, and polyhydroxy groups present. The carbonyl group is present in aldehyde, ketone, and alcohol group present as a polyhydroxy group.

Answer to Problem 65A

Disaccharides sugar containing two monosaccharide units.

Explanation of Solution

Disaccharide is form with joining of two monosaccharide, they are linked together with the glycoside linkage.

Conclusion

Carbohydrate classification is based on the carbon numbers. The monosaccharide contains six-carbon or less than carbon, disaccharide contains two units of monosaccharide and polysaccharide form with joining a large chain of monosaccharide.
