message: Xylan 
Wikipedia Critique on Xylan for Writing class 5180, Fall 2018: The article I choose to work on is under the category of "Stub article " which mean that it is very short and need a lot of improvements. Also, the information mentioned in the article is not comprehensive, clear and coverage is not broad. There is no lead section. It is just an overview of the topic in few lines. There are only eight sources used to cover this broad topic. Out of eight, 2 sources are recently added. The structure of the article is not clear, table of contents is missing and you will not be able to scan article what you will find in this page until you do not read the whole information. In the first introductory paragraphs, references are missing and most of the references are old thus need to add recent references. You will observe first reference provided at the end of second paragraph. No assumptions are made in this article. This page just talk about a little about the structure of Xylan, composition in different kinds of woods and a little about the nutritional importance. 
This article has no clear structure, headings and sub headings are missing. Only one image of Xylan structure is provided which is poorly labelled and footnotes have missing information.The references used in this article are mostly from reliable source like a book chapter or some peer reviewed article like Advances in Polymer sciences in Springer. Also, better and recent images or photographs can be added to show the effect of mutation in Xylan synthesis genes in plants. TJavaaid (talk) 16:40, 22 October 2018 (UTC)

message: The image is wrong.  The placement of brackets implies that xylan is connected via O-O linkages, which is not the case.  — Preceding unsigned comment added by Skaijo (talk • contribs) 14:44, 3 May 2012 (UTC)

message: Xylan is the third most abundant biopolymer after cellulose and chitin. It has variety of applications that affect human well being e.g Xyalns are important functional ingredient in baked products that affect the quality of cereal flour for bread making. Also, main constituent of xylan can be converted to xylitol which is used as natural food sweater help to reduce dental cavities and sugar substitute for diabetic patients and many more applications in livestock industry too.
Xylans are Polymer of β-(1,4)-linked xylose residues with side chains of α-arabinofuranose and/or α-glucuronic acid residues. The structures of xylans vary depending upon species, tissues, or even cells within the same tissue which I need to talk about to give better picture of Xylan. Xylans are synthesized through the action of many glycosyltransferases (GTs are the group of enzymes that catalyze the formation of glycosidic bond) that are assembled into complexes residing in the Golgi not like cellulose and callose which are synthesized on plasma membrane.TJavaaid (talk) 16:53, 22 October 2018 (UTC)
thread_title: Xylan Importance

message: The lead section of this article was not well written and most of the information was missing about structure, genes involved in the formation of xylan. Some information was written explaining the importance of this biomolecule but was not well connected with daily usage. It was not focused and organized well. So, I added figure showing the cell wall and important polysaccharides collectively made it strong and first barrier of defense for plant cells. In that figure, one can see bigger picture of plant cell wall and xylan is abundant polysaccharide of secondary cell wall of trees while all cell walls of grasses. I organized article with subcategories so that one could get information easily and provided secondary and primary sources to justify information.Overall, many aspects e.g. Xylan synthesis genes discovered in dicots and monocots, the enzymes involved in the assembly of Xylan, the localization of  Xylan synthesis enzymes in the cell added to improve the quality of this page. --TJavaaid (talk) 22:00, 21 November 2018 (UTC)
replies: text: Thank you for pointing out it. I have got one source which says it as a section heading itself%mdash;and it explains the claim too! The site is www.yiduoli.com. I am not sure whether it is reliable or not, but if it is, we have got a citation. Thank you and happy editing. VanischenumTalk 09:14, 28 July 2012 (UTC)

text: I read it as meaning the stuff is non-nutritional.  The term "anti-nutritional" is misleading, and possibly incorrect.  Anti-nutritional implies it would be harmful to animals that ingest it, and it's doubtful any farmer would knowingly give his livestock something their feed that harms them.  What it really may mean is that animals have nothing in their digestive tract that can break down xylan molecules into simpler substances that can be absorbed and used by the organism.  As for the grammar, it appears the sentence was lifted from the yiduoli.com page, a Chinese site rife with stilted English and grammar and absolutely atrocious typography, hardly a good reference for proper use of the English language.  Incidentally, yiduoli.com appears to be peddling xylanase, an enzyme that breaks xylan down, probably as an additive to feedstuffs so livestock get more nutrition out of otherwise indigestible plant matter. — QuicksilverT @ 22:46, 2 March 2013 (UTC)

text: Hint from experienced editor: "Wikipedia training" is for the birds (or something that instructors - who never actually edit Wikipedia - dream up to keep students occupied).  The main thing we are looking for here are good sources (WP:SECONDARY, WP:TERTIARY and decent writing.--Smokefoot (talk) 21:39, 25 October 2018 (UTC)

message: According to SciFinder: 26396 publications discuss xylan. Should we aim to cite all of them? Of which 13733 appeared since 2012, of which 252 are reviews.  Of the top 10 reviews, only one is currently cited.--Smokefoot (talk) 20:54, 15 September 2022 (UTC)
