the image on the page is broken. anyone want to fix it? 68.122.42.119 (talk) 08:20, 15 September 2008 (UTC)

ok so i just fixed it Amaher 12:16, 16 May 2007 (UTC)

Amaher 12:15, 16 May 2007 (UTC) There is a mistake on the diagram at the rop of the page; it is ethanol reacting with glucose in the picture, but the caption says methanol.

 * I have now corrected this. As a side note, it did not actually say methanol in the ¨caption¨, as you put it - but in the picture description, meaning there is no need to change the picture itself. I say this solely to encourage others to correct any errors themselves. Nirmos (talk) 12:51, 15 April 2010 (UTC)

Hi, I'm Two questions 1. is cellulostic 'beta acetal bond the one that holds links saccarides into polysaccarides 2. if it is why is it so difficult to break chemically?

I'd like to know because I'm blogging about biofuels (though in the distant past I studied synthetic polymer chemistry) and breaking cellulose into simple sugars is one way to greatly increase the amout of fermentable material available for ethanol prodcution. All I can offer in terms of recompense for your time and effort is publication on the Big Biofuels Blog

trying to undestand why enzymes are the only things that can break the cellulostic beta acetal bond.

what is this all about? im so bad at chemistry! majorly stuck on an assignment!!

If you don't have enough background in chemistry, you've got to start at the very beginning (e.g: covalent bonds, ionic bonds etc... ) because this stuff is advance in some sort--it is a part of Biochemistry II.

Good luck!

Some people spell this as glucosidic.. is this wrong or just an alternative? 203.218.87.192 01:45, 9 April 2006 (UTC)

"Glucoside" and "glucosidic" refer to a glycoside in which the sugar part is glucose. So every glucoside is a glycoside, but not vice versa. AxelBoldt 03:46, 9 April 2006 (UTC)

Correct notation?
Hi, can someone please explain how to correctly write a glycosidic bond? Is it α-1,4 or α(1->4)? Or what does it depend on when to write which form? Is there an official norm and where can I find it? In scientific publications I find both notations, does it maybe depend on the journal? --Magistra Sylvia (talk) 10:08, 3 March 2017 (UTC)

Also, what the heck do the numbers even MEAN? 1,6? 1,4? 1,3? A link about this topic would make a lot more sense than just saying: "It's a 7 sixteenths hoop-a-doop with a backwards hyper-transient three-eighty-seventeen-zeta coupling along its transverse axial dingleling." Same goes a for a lot of the graduate level articles on here; provide a link to something closer to intermediate level information in the beginning of your article for contextual learning.73.83.14.130 (talk) 19:04, 24 October 2017 (UTC)

Glycosidic linkage
How does it take place ?? Mechanism please Parth Singh knp (talk) 07:23, 19 August 2017 (UTC)

Alpha/beta notation
If you go by the definition provided here: "An α-glycosidic bond is formed when both carbons have the same stereochemistry, whereas a β-glycosidic bond occurs when the two carbons have different stereochemistry" then neither the diagram nor anything else makes sense. I am relatively certain that this definition is wrong. If no one can explain to my why this statement makes sense, I'm going to change it. Baconfry (talk) 02:55, 2 April 2018 (UTC)
 * Yeah, that caught my eye too. I'm quite sure you're right about this, and since you haven't performed the change yet, I did; [ over 14 years] is way too long for such blatantly incorrect information to persist on Wikipedia. (My best guess is that the anonymous editor who did this was a student who saw the stereochemical differences between α and β (1-4) dimers of glucose and mistakenly overgeneralized that as a definition.)

Ethanol Methanol
Diagram shows Methanol, but text refers to Ethanol? 120.18.20.105 (talk) 03:32, 17 May 2022 (UTC)
