"Students could use chromatography, with known standard solutions, to separate a mixture of monosaccharides and identify their components."

I don't remember doing chromatography during biological molecules. How would I word this?

This would come under analysis rather than biological molecules.

It's not too hard, just watch a few videos on youtube.

Different monosaccharides will have different Rf values so when you seperate them via chromatography then you can identify them.

Hi, I've just come across this too in an exam will we be given the Rf values of each monosaccharide in the spec?

They will give you the Rf value in the question.
Or, they could give you an equation to work out the Rf value given other data.
It's nothing to stress over though!
