Is glucose a large or small carbohydrate?
Small. Glucose is the simplest of all sugars C6H12O6 (with the
numbers smsll and subscript). This is why glucose is given to
athlletes or anyone requiring energy quickly, as its small
molecules are quickly absorbed into the blood. Other carbohydrates
have larger molecules (like sucrose - normal sugar - which has a
molecule that resembles 2 glucose molecules joined together) or
giant molecules (like starch) all of which have to be broken down
by enzymes in the body to produce glucose so that it can be
absorbed into the blood. This takes time, and so other 'large'
carbohydrates take longer to have an effect than small ones like
