Talk:Glycosaminoglycan

Production ?
Production section talks about "protein cores" which aren't mentioned in Structure. Seems to be about proteoglycans instead. Rod57 (talk) 19:32, 29 August 2008 (UTC)

==i am curious about the origin (e.g., Greek or Latin roots) of the term "Glycosaminoglycan". Would be a nice addition if you know it."

Murein
What about murein? http://en.wikipedia.org/wiki/Murein Isn't murein a GAG, too? 178.197.232.115 (talk) 16:45, 29 June 2012 (UTC)

Sloppy Definition
The opening definition states that GAGs are polysaccharides (which are carbohydrates, which contain only C, H, and O). Yet the first two examples given are chondroitin sulfate and hyaluronan, which, containing S or N, are not carbohydrates.CountMacula (talk) 20:26, 21 May 2014 (UTC)

In the classical sense, yes, carbohydrates only consist of C,H,O, however, we've long since expanded 'carbohydrates' to include hexosamines like N-Acetylglucose amine, N-acetyl galactosamine, and even a molecule like neuraminic acid. Sulfated forms of carbohydrates would still technically be considered carbohydrates in most circles that study carbohydrate biology. The definition is fine. — Preceding unsigned comment added by Sialic acid (talk • contribs) 18:43, 24 March 2016 (UTC)

Bonds
What bonds are between sugars of GAG? --Impériale (talk) 18:45, 4 March 2015 (UTC)

Too technical
I agree with the "too technical" tag at the top of the page, which was left in 2015. The intro paragrapgh is incomprehensible. I have no idea what they are talking about, and I am an educated person.SamanthaB55 (talk) 02:31, 21 August 2016 (UTC)

Disaccharides...
In the text, it says "Except for keratan, the repeating unit consists of an amino sugar, along with a uronic sugar or galactose."

But isn't Keratan Disaccharides: Amino sugar (N-Acetylglucosamine) + Galactose?

I wonder if the text was initially this: "Except for keratan, the repeating unit consists of an amino sugar, along with a uronic sugar", and then someone added the galactose?

Could someone enlighten me?
