Chapter 24, Problem 5STP

Interpretation Introduction

Interpretation: To match the category of an organic compound for the given biological molecule.

Concept introduction: A polymer is formed by joining a large number of macromolecules that are known as monomers. A polymer is composed of repeating monomeric units that are bonded together.

Answer to Problem 5STP

Monosaccharides are most closely identified with a biological molecule i.e., carbohydrates.

Explanation of Solution

Carbohydrates are biochemical substances that contain a polyhydroxy aldehyde or polyhydroxy ketone group.

The classification of carbohydrates is done on the basis of molecular sizes which are as follows:

• Monosaccharide
• Disaccharide
• Polysaccharide

Monosaccharides are simple molecules or monomers which form carbohydrates. Such as glucose and fructose.

Disaccharides are carbohydrates formed when two monosaccharides are bonded together. In a disaccharide, the bond between two monosaccharides is known as glycosidic linkage. Some examples of disaccharides are sucrose, maltose, and lactose.

When more than two monosaccharide units are joined together, it yields into polysaccharide. Such as starch and cellulose.

Conclusion

Monosaccharides are most closely identified with a biological molecule i.e., carbohydrates.
