Right. But try do the little hand experiment. The palms have to face the same direction btw!

anonymous · Answer

frostbite · Answer

Can you make them overlap? ;)

anonymous · Answer

I think I didn't get!
What I have to do? :o

frostbite · Answer

Take one hand and place the other in top of it. Does the hands overlap or is there some kind of problem? ;)

anonymous · Answer

Haha I did!
Now I'm typing..
What this experiment is supposed to be?
2 forms of glucose is equivalent to left and right in common terms.?

frostbite · Answer

Exactly. What i wanted you to try find out is that your hands are mirror images of each other... and guess what... the same thing goes for molecules! :)

anonymous · Answer

Those two forms of glucose are?

anonymous · Answer

Cellulose and starch right?

frostbite · Answer

We call one alpha $\alpha$ and the other one beta  $\beta$. The difference is like in your hands that there are a mirror image.
The mirror image does so different bonds are created, and you may have guessed it, our enzymes (in a human) can only catalyze one of the mirror image, while for example a cow that can eat grass and starch can catalyze both.
we therefor say:
Alpha-glucose is in starch.
Beta-glucose is in cellulose.

This is somehow understandable?

anonymous · Answer

Yes!
I got it now!
I think.....

A little example of this using two molecules (not glucose, but just two molecules):
