Prelab: complete this in your lab notebooks this lab has a different prelab format as it is not an experiment (so no hypothesis or variables. Carbohydrates: reducing sugars and starches reducing sugars some sugars such as glucose are called reducing sugars because they are capable of transferring hydrogens (electrons) to other compounds, a process called reduction when reducing sugars are mixed with benedicts reagent and heated, a reduction reaction causes the benedicts. A reducing sugar is a carbohydrate possessing either a free aldehyde or free ketone functional group as part of its molecular structure recall from lectures that functional groups are the regions of a molecule that gives it particular properties a single molecule can have more than one functional group as part of its structure when a molecule.
