To what category does a mixture of glucose and fructose belong?

A mixture of glucose and fructose is classified as a disaccharide because it combines two monosaccharides. In biochemistry, monosaccharides like glucose and fructose are the simplest form of carbohydrates, and when two of these molecules undergo a condensation reaction, they form a disaccharide. Specifically, when glucose and fructose bond together, they produce sucrose, which is a well-known disaccharide found in many plants.

Disaccharides are characterized by their structure, which consists of two monosaccharide units linked together. This category encompasses other common sugars like lactose (formed from glucose and galactose) and maltose (formed from two glucose molecules).

The other categories mentioned do not apply here because amino acids refer to the building blocks of proteins, polysaccharides are larger carbohydrate structures made up of many monosaccharide units (like starch or cellulose), and monosaccharides are the simplest form of sugars, not a mixture.
