Sphingomyelin

 * I was looking over one of your diagrams recently in the course of some work I'm doing and I noticed a possible piece of misinformation. In your diagram "membrane lipids" you have sphingomyelin listed as a phospholipid. I believe that in fact it is a sphingolipid. My understanding is that to qualify as a phospholipid, there must be an ester bond at both the 1' and 2' positions of the glycerol, as well as to the phosphate at 3'. Is your understanding of the matter different or is this something that should be addressed? MDougM (talk) 00:39, 17 December 2008 (UTC)

By definition, that you can find in books such as Stryer's "Biochemistry", phospholipids are "membrane lipid" derivatives of either glycerol, and hense this sub-group is called phosphoglycerides, or sphingosine, a group containing only one member - sphingomyelin.

Interesting. I looked it up in Stryer and, sure enough, that's how it's categorized. I had been going off another textbook that gave an alternate scheme, but I agree that Stryer is a pretty accepted resource. Thanks for talking it over. --MDougM (talk) 01:01, 21 January 2009 (UTC)

Review
I'll take a look at it either tonight (once I get this damn paper rewrite off my desk) or tomorrow once I've got some sleep! Tim Vickers (talk) 23:37, 25 February 2009 (UTC)

Finishing the review
I am going to close the review over the weekend and give a final evaluation, so please finish any changes by the end of Friday. Thanks! Diderot&#39;s dreams (talk) 15:14, 3 March 2009 (UTC)

Also, I should say that at this point the article is clear enough and short enough for GA. I've added a 5th paragraph that concisely adds the history, model systems, and commercial applications to the lead. The lead now needs shortening to 4 paragraphs, with some condensing to make it a little shorter. If you guys can do that, that pretty much takes care of everything.

One more thing...
I've looked around, and I see you've added a great deal of information about lipid bilayers, in both the main article and several subarticles, some of which you created yourself. It seems like you've almost single-handedly written all there is to know about lipid bilayers for Wikipedia. I've spent a lot of time talking about how to say things, about the right words, not too long, not too short, but the most important thing, of course, is that something is said, the information itself. There is no encyclopedia without it. And you've added a great deal of it, and good quality too. So I think you deserve this.

If I can be of any help in the future, just let me know! Diderot&#39;s dreams (talk) 05:09, 6 March 2009 (UTC)

lipid bilayer
Thanks for the message and sorry I didn't get back sooner. Go for it, what you think is right. Slight Smile  13:59, 27 March 2011 (UTC)

ArbCom elections are now open!
Hi, You appear to be eligible to vote in the current Arbitration Committee election. The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process.
