Isn't this just so interesting.



Gwandle doesn't want me to do biology.

What's the chemical formula of fructose? It's C6H12O6, the same as glucose! If these two molecules have the same chemical formula, how can they be different molecules? Well, they have the same chemical formula, but they have different structural formulas. The ring and chain structural formulas of both glucose and fructose are shown in the figure below. These different structural formulas are the reasons behind the taste difference and other chemical differences between glucose and fructose.

Glucose and fructose belong to a class of compounds known as monosaccharides (mahn uh sak' uh rides), which are also called simple sugars.


Monosaccharides
– Simple carbohydrates that contain 3 to 10 carbon atoms

The reason that these are called monosaccharides is that they form the basic building blocks of more complex carbohydrates called disaccharides (dye sak' uh rides) and polysaccharides (pahl ee sak' uh rides).

Polysaccharides – Carbohydrates that are made up of more than two monosaccharides

These more complex carbohydrates form the basis of much of the food that we eat.

No that is not interesting in anyway. like I said too many big words that no one knows to explane(sp) just about everything in matter. to bothersome.

PJ said...

PJ said...

well you girls get to cheat at everything(board games, card games, snowball fights, races)(hehe) so some times guys can to right.

hmmm, one question is

identify the following as an atom, element, or molecule:

notice i didn't tell you what was supposed to be identified.

PJ said...

see your cheating again.

zorg said...

dont tell your mom, please!

PJ said...

haha. hehe. evil laugh. baw hahahaha. I won't.

zorg said...

whew, what a relief:) im on nates laptop and this thing has perental controls that block a lot of stuff. so i wont be posting tonight.

PJ said...

I did make a post. I don't know what it is but I like writing now and I have a longing for others to hear the word so the two together kind of make a lot of posts.

zorg said...

writing is fun. to bad i cant look at what you wrote. this internet protection makes it so that i cant look at your blog, i cant even see the pictures on my own blog. drives me nuts.

Granny Kate said...

Well, since technically you are only supposed to be on the internet on the living room computer, I'm glad the laptop has those controls.

Sarah, every now and then you might play a different song on your blog. ;)

zorg said...

there are other songs on there, you just have to skip ahead to them.

the cat is wanting me to play with her, not do my biology.

Rand said...

What are you saying? Biology isn't interesting???

Hmmm....

zorg said...

Its relatively (sp) interesting. once I start understanding it,it gets interesting. I am looking forward to studying animals not cells and the like. Well actually I am studying animals, just not studying them they way that interests me.
