# What monosaccharides are in sucrose?

Jun 27, 2015

Glucose and fructose are the monosaccharides in sucrose.

#### Explanation:

The structure of glucose, ${\text{C"_6"H"_12"O}}_{6}$, is

The structure of fructose is

If we "flip" the structure of fructose, we get the structure shown below.

The $\text{OH}$ on $\text{C-1}$ of glucose can combine with the $\text{OH}$ on $\text{C-2}$ of fructose to form sucrose

We could write the equation for the formation of sucrose as

 underbrace("C"_6"H"_12"O"_6)_color(red)("glucose") + underbrace("C"_6"H"_12"O"_6)_color(red)("fructose") → underbrace("C"_12"H"_22"O"_11)_color(red)("sucrose") + "H"_2"O"
