Talk:Cytosol

When ??

I am not a cell biologist and interest is only a passing one but I do know that since this is the 21st century there can't have been a 25th. (Under definition.)

Comment

Test 2

Paragraph 1, sentence 2 seems a bit inaccurate: I don't believe that protiens can 'act as ribosomes' (as it currently states).

Fixed - Nunh-huh 17:30, 15 May 2005 (UTC)

The first section is a bit unclear: it seems to say that the cytosol doesn't include the organelles, and then to pay that the cytosol contains the organelles. I think I understand: it is a semantic difference, ie, when we say cytoplasm, we refer to the cytosol itself along with all the organelles, whereas the cytosol is just the fluid in which the organelles are embedded. But it could be clearer.ClarkFreifeld 20:38, 20 January 2006 (UTC)

GA Review

This review is transcluded from Talk:Cytosol/GA1. The edit link for this section can be used to add comments to the review.

• Prose
  • The water discussion in the lead isn't very clear. Also, consider shortening the lead.

Shortened and reworded.

• • First paragraph of Function should be split into more sentences.

Done.

• Content
  • I'd change the proteins section name to macromolecules and add a passing mention of RNA and, more importantly, prokaryotic DNA.

Done.

• • A mention of osmoprotectants in the ion section would be nice

Added.

• • Water activity in the table would be a good addition, though not needed.

I can't find anybody "bold" enough to be willing to put an exact figure to it! :)

• • "Amino acids in proteins" can't really be measured in millimolars

I agree, I was a bit dubious about this myself, but that's what the source says and I haven't found a better summary anywhere else Table 15-1

• References
  • "others may involve more loosely-associated complexes that are very difficult to study outside the cell" the sources are old, are they still poorly studied?

Very! This is a much-neglected area in my opinion.

• Reliable sources
  • All fine. No misquotations spotted.

• Neutrality
  • Not really any problem. The article should hint that one shouldn't use the terms protoplasm, nucleoplasm and aqueous cytoplasm (they are not commonplace after all), but I think it does.

Yes, there are no sources that spell this out explicitly and some even use "cytoplasm" and "cytosol" as if they were synonyms. "Nucleoplasm" is occasionally used, so I thought it was worth adding.

• Stability
  • It is stable

• Images
  • Lead picture has no reference or info on how it was produced.

I drew it myself, I'll add where I got the idea and relative scales. I don't think it is quite crowded enough to be honest, but adding more will make the individual components a lot less distinct so I went for the lesser of the two evils. Tim Vickers (talk) 20:59, 28 September 2008 (UTC)

I didn't notice the compartments until you pointed it out, so more crowded wouldn't be too bad. Narayanese (talk) 06:02, 29 September 2008 (UTC)

I'm putting it on hold, I trust your ability to fix the little left for GA. Narayanese (talk) 18:31, 28 September 2008 (UTC)

It's a fine article, and while there is room for additional detail in the Properties and composition section, I' say it covers the major aspects along with a selection of minor ones. Time to GA-pass it. Narayanese (talk) 06:02, 29 September 2008 (UTC)

Fatty acid synthesis

It is listed as taking place in the cytosol. For what organisms? I know plants use chloroplasts and ER for that. Narayanese (talk) 20:30, 29 September 2008 (UTC)

Corrected, thank you. I always tend to forget about plants for some reason. Tim Vickers (talk) 20:54, 29 September 2008 (UTC)

Ugh, I forgot about the apicoplast as well and I used to share an office on somebody doing their PhD on fatty acid biosynthesis in Plasmodium. Now that's annoying! Tim Vickers (talk) 20:58, 29 September 2008 (UTC)

Haha ;). The pentose-phosphate pathway is another of those plant exceptions as far as I can find, but I see you've added a blanket "things may vary" statement which should cover that and however algae work. Narayanese (talk) 11:31, 1 October 2008 (UTC)

Water Section

The article states "Most of the cytosol is water, which makes up about 70% of a typical cell by volume" Is the 70% referring to the cytosol taking up 70% of the cell, or that 70% of the cell is water? It isn't very clear. Unfortunately the reference provided doesn't say anything in the abstract and I can't get to the whole article. Smartse (talk) 16:48, 23 April 2009 (UTC)

I've added a link to the full text, it is discussed in the section titled "Water in Intact Cells", which states "a typical cell contains 70% water", so this is the total cell, not just the cytosol. I've reworded this sentence a little, to try to make it clearer. Tim Vickers (talk) 19:06, 23 April 2009 (UTC)

Osmosis mention under Ions is incorrect

The second paragraph (after the table) says: "if the ion levels were the same inside a cell as outside, water would enter constantly by osmosis - ". This is backwards -- osmosis is driven by differences in concentration. —Preceding unsigned comment added by 67.249.203.18 (talk) 12:01, 29 March 2011 (UTC)

Anions with most concentration?

Is it CL-, SO4-, HCO3-, HPO4-, or CHCOO-? I think HPO4- because there's a P in there. --118.96.148.144 (talk) 21:05, 23 January 2014 (UTC)

Intra-organelle fluid

 The "cytosol" article defines cytosol as excluding fluid inside organelles. I can't find ANYWHERE what the fluid inside organelles is called. 2602:306:BC65:42B9:81A1:34FD:A843:814A (talk) 21:46, 20 November 2022 (UTC)
