Name that Carbohydrate.

Hey guys,

The instructions and exercise is quite simple. Look at the six structures below and name the Carbohydrate illustrated. You may answer by commenting to the post. I know this may be a monotonous act but it’s a good revision of Carbohydrates. I will leave it up for a week and then post the answers. So here’s the challenge, Name A to F. Be accurate, I want the name, the type of bond and a function/use of the Carb in question.

A.

lactose

B.

cellulose

C.

maltose

D.

sucrose

E.

starch

F.

glycogen
