What monosaccharides are in sucrose?

Answer 1

William Albracht

Glucose and fructose are the monosaccharides in sucrose.

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"#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
