Amino acids vs amino acid residues[edit]

Peptides and proteins do not contain amino acids. That much all biochemists and chemists agree on. The article probably should make this point clear. In fact, I think that free amino acids are rare in nature. The key term is amino acid residue. Possibly if this term were introduced, there would be less confusion. On the other hand possibly other editors find this distinction to be pendantic. --Smokefoot (talk) 04:26, 10 November 2013 (UTC)

Oddly, I agree with your edit, but not your edit summary. Proteins (or at least polypeptides) are literally polymers of amino acids despite the fact that they don't contain intact amino acids. In the same sense, polystyrene is a polymer of styrene, even though it contains styrene residues, not literally intact styrene monomers. This is of course 1000 times more pedantic than your original argument. (+)H3N-Protein\Chemist-CO2(-) 15:54, 12 November 2013 (UTC)

Hello fellow Wikipedians,

I have just added archive links to one external link on Protein. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

Question? Archived sources still need to be checked

Semi-protected edit request on 21 October 2015[edit]

Source:

A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than about 20-30 residues, ...

Edit request: Second sentence, sub phrase "less than about 20-30 residues," should be improved for clarity. Less than 'approximately' 'an approximation' is redundant. No need to specify "about" when you're saying "20-30," it is already understood this is an approximation. This gives the idea that it is not, in fact, 20-30, but perhaps 18-25, or 21-32, etc. If such is the case, it should be specified, not assumed.

Thank you.

Tag[edit]

I have tagged the article with a lead too long tag. My edit conforms to WP:LEADLENGTH and should not be reverted without providing a good reason. Also, at the time the article got promoted to GA‐status, the lead was shorter then it is now. —MartinZ02 (talk) 13:51, 19 July 2016 (UTC)

What do you think should be removed from the Lead? Graham Beards (talk) 20:07, 19 July 2016 (UTC)
