Out of curiosity, how did you come up with the percentage of 98.6%? :lol: :lol:

Through exhaustive statistical analysis! Nah, I made it up :)

I think that Glycogen consists more than 8-12 glucose molecules..I'm sure that you mean is Oligosaccharides.. :D
Let me explain it in Physics..potential energy is stored in the form of bond energy. So, the more bond energy a molecule have, the more potential energy it has....so, no doubt GLYCOGEN

Agreed Victor.

As for glycogen, I found this on the web:

Glycogen is a glucose polymer resembling the starch in plants (so it is sometimes called "animal starch"). Glycogen is a highly branched glucose polymer. It is formed of small chains of 8 to 12 glucose molecules linked together with α (1→4) bonds. These small chains are in turn linked together with α (1→6) bonds. A single molecule of glycogen can be made of up to 120,000 molecules of glucose. It is stored in the form of granules in the cytosol, or cell fluid.

So you're right. It's formed of chains OF 8 to 12 glucose molecules bonded together.

Is it oglio or polysaccharide? I've never understood the difference.

Actually the glycogen molecule is a bit more complex than that. There are 4 enzymes that participate in it's synthesis and all of them remain atached to the molecule whn it is "finished". Of these, the most important is called glycogenin(spelling?) which is the core of the glycogen molecule. Also, it does not resemble strach it actually resembles a component of starch called amilopectine, but it is more ramificated(is that a word?)

Definitely Glycogen. ATP, it's great and all, but not as great of an energy provider as glucose, which is not as good of a provider as glycogen. I actually had a question like this one on an exam. The question was:
Which of the following has the potential energy?
A. ATP
B. Lipids (obviously not right)
C. Glucose
D. Starch

The answer is Starch of course. If you think in the same context, and replace Starch with Glycogen, then Glycogen is the correct answer. But just knowing what I do, the answer is GLYCOGEN. I'm 200% sure(and that's pretty darn sure)!!!

"oligo-" means "few"
"poly-" means "many" :lol:

yeah, just think of a monosaccharide as an (O), so if you use (O) as a monosaccharide, then an oligo- would be (O-O) while a poly would be (O-O-O.....) so on and so forth. Got it?

Okay that much I knew. But what defines oligosaccharides? 2,3,4? Is there a specific number....or?

2-10 (aproximately)-------> Oligosaccharide
more than 10 (approximately)---> Polysaccharide

Mmm, that's what I don't like about oligosaccharides.... Too subjective. It should bi mono, di, and poly. Oligosaccharides are too.....elusive.
