The Million-Dollar Bio Question

Okay, three food samples.

A = starch
B = glucose
C = sucrose

They're all hydrolysed (by boiling in dilute hydrochloric acid then neutralised with sodium hydrogen carbonate).

Then they're tested with Benedict's solution.

Will all three test positive?

  1. All 3 should test positive since they are all hydrolysed into reducing sugars :)
