Question

What monosaccharides are in sucrose?

Answer 1

Glucose and fructose are the monosaccharides in sucrose.

Explanation:

The structure of glucose, `"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 `"OH"` on `"C-1"` of glucose can combine with the `"OH"` on `"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"`
