I did significant work on the cell membrane image when it was a Featured Picture Candidate and thought that the article could benefit from it. It shows the membrane more clearly and places it in context within the cell. Also shown are a more detailed view of the bilayer and phospholipids that make up a critical part of the membrane. If you have any corrections or suggestions I would like to hear them. [[User:Dhatfield|Dhatfield]] ([[User talk:Dhatfield|talk]]) 15:43, 18 June 2008 (UTC) |

This page is a very in depth view of the cell membrane, scientifically precise etc. But it's hugely daunting to someone without a deep biological background. There's no link to an alternative laymans version of the page, and [http://simple.wikipedia.org/wiki/Cell_membrane] has barely any content. Any chance of some of you working on either a laymans wiki page under a slight variant name (I'm not sure how standard they are, but maths articles often do so) or working on the Simple English version? -[[Special:Contributions/94.192.232.74|94.192.232.74]] ([[User talk:94.192.232.74|talk]]) 16:19, 28 March 2009 (UTC) |

Revision as of 16:19, 28 March 2009
Template:Wikiproject MCB Template:Cell Signaling Project
Under the Composition section, my group and I have a few proposed additions of content. -Provide the proportions of each of the three major lipids in the plasma membrane. (The Cell: A Molecular Approach. 2nd Ed. https://www.ncbi.nlm.nih.gov/books/NBK9898/) -Add examples of integral proteins with functions (Molecular Biology of the Cell. 4th Ed. https://www.ncbi.nlm.nih.gov/books/NBK26878/) -Mention in composition intro that composition is not set, but constantly changing for fluidity and changes in the environment, even fluctuating during different stages of cell development. (Assessment of Membrane Fluidity Fluctuations during Cellular Development Reveals Time and Cell Type Specificity. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4928918/) -Adding explanation of what a carbohydrate is and what it offers to the cell membrane function, as well as adding a link to homing receptor. (Cell-surface carbohydrates in cell recognition and response. https://www.ncbi.nlm.nih.gov/pubmed/3011937) [User:Cottrill41|Cottrill41]] (talk) 19:08, 4 October 2017 (UTC)Cameron Cottrill, Deena Dahshan, Kaitlin Stiltner, Haylie Bryant
Under the history section, my group and I believe that there should be some additional content. Even though there is an article about the history of the cell membrane linked to the history section, we believe there should be some additional information added to this page such as a timeline and brief description of various models of the cell membrane and important figures that played a vital role in the determination of the structure of the cell membrane. We would focus on the origin of the cell theory and the evolution of the current fluid mosaic model of the plasma membrane which is widely accepted today. These additions would not only be important for historical relevance, but would be an adequate starting point for describing the significance of plasma membranes in various organisms. Justin Merritt 206.212.41.153 (talk) 17:51, 10 October 2017 (UTC) (Group: Justin Merritt, Delaney Ellis, Mary Schmeck, Saul Garcia) Under the Prokaryotes section, our group plans to provide further information on the structures and functions of prokaryotic cell membranes (for example, lipid rafts and integral outer membrane proteins), and to describe how these differ from those of eukaryotes. We plan to discuss other types of prokaryotes in addition to bacteria, to include gram-positive bacteria as well as gram-negative. We also plan to add links to terms in the section which have not been defined, such as "bleb", and we proposed moving the Prokaryote section to the bottom of the page in order to present all the other relevant information about membranes before discussing them in the context of organisms.

Caveolae
Can someone well-versed on this topic incorporate Caveolae into this article? Kingturtle 00:08 May 14, 2003 (UTC)
No I can't help you out, Kingturtle...I'm sorry. If you are a teacher, I strongly recommend this site to your students. I am a high schooler in biology and have found this site very helpful in looking up words and information. Plus, it's free!! I strongly recommend it! Happy exploring with Wikipedia!!!!
- I think it's worth having a separate article; research in the field is ongoing and the caveolae article could potentially expand considerably. It should be linked from here, though; it it? I'll check. --Chinasaur 00:39, 8 Sep 2004 (UTC)
Transport
I can't do it right now, but someone should add a section to this article about: 1) junctions between the cell membrane (i.e. desmosomes, tight junctions, hemidesmosomes, etc.) 2) all three transports (right now there are only two - all three are simple, facilitated, and active).
- I also can't do it right now, but someone should add a section on apical and basolateral membrane, and redirects too. --Eleassar777 14:34, 24 May 2005 (UTC)
Artificial outer membranes
I added today an article about polymersomes and checked out the liposome article. Both are currently stubs. I don't have the expertise required to write about them beyond what I already wrote (and that's not much and probably lacking in various aspects) but it would be nice if someone qualified could write them.
Link to this article should be added as well, as should links to them be added to this article. I'd also be very pleased if someone could start an article about artificial cells. --Khokkanen 10:34, 12 July 2005 (UTC)
Structure of biological membranes
This needs to be improved. I inserted a few phrases, please fell free to edit anything. Note that biological membranes include carbohydrate component, in addition to lipids and proteins. Biophys 02:45, 30 January 2007 (UTC)
Fluid mosaic model
Fluid mosaic model redirects here. I think it might be better to add that topic to biological membrane though, for the simple reasion that it is more general while this article is the more specific case. A cell has other membranes besides its plasma membrane, but the lipid bilayer/fluid mosaic model applies to all of them. - tameeria 04:24, 9 March 2007 (UTC)
Illustration of a cell membrane
This picture is not correct. The legend of this figure sounds weird to me. I've got the impression it mixes different systems of protein classification: the integral protein is globular, the transmembrane helix is intergral, the channel protein is a transport protein, peripheral protein are different from surface protein... that's very confusing! The term "globular" is rarely, if not never, used for membrane proteins. It qualifies the shape of (soluble) proteins. Actually, this is the opposite of "fibrous proteins". The integral proteins, as shown on the picture, are bi/polytopic proteins in fact. Integral means "tighly bound to the membrane", and not necessarly transmembrane. In the same idea, "peripheral" means "not tighly bound to the membrane". Only biochemical tests can say if the case for a specific protein... So the "peripheral" protein showm in the picture is in fact a monotopic protein. That's all you can say without performing tests. Actually, the surface protein is probably also a peripheral proteins. Finally, cholesterols look oriented in the wrong sense with their aliphatic tails oreitned toward the hydrophilic heads of phospholipids. cheers. -- 22:56, 23 April 2007 (UTC)
- also, "peripheral" is spelt wrong Crana 11:10, 7 May 2007 (UTC)
Protein functions in cell membranes
I'm proposing to merge the contents of the article Protein Function in Cell Membranes either into this one or into membrane protein. - tameeria (talk) 02:22, 9 December 2007 (UTC)
- I'm behind you on that. I think that membrane protein would be the more appropriate place to merge it. – ClockworkSoul 05:13, 19 April 2008 (UTC)
Cell Membrane Difference
In the article, it says there are different type of cell membrane in different cells. In effect, does it mean a plant cell's membrane have the different composition than an animal's cell's membrane? And should we state it?Rider555 (talk) 02:25, 19 April 2008 (UTC) Rider555
New diagram of cell membrane
I did significant work on the cell membrane image when it was a Featured Picture Candidate and thought that the article could benefit from it. It shows the membrane more clearly and places it in context within the cell. Also shown are a more detailed view of the bilayer and phospholipids that make up a critical part of the membrane. If you have any corrections or suggestions I would like to hear them. Dhatfield (talk) 15:43, 18 June 2008 (UTC)
A non-technical alternative?
This page is a very in depth view of the cell membrane, scientifically precise etc. But it's hugely daunting to someone without a deep biological background. There's no link to an alternative laymans version of the page, and [1] has barely any content. Any chance of some of you working on either a laymans wiki page under a slight variant name (I'm not sure how standard they are, but maths articles often do so) or working on the Simple English version? -94.192.232.74 (talk) 16:19, 28 March 2009 (UTC)
