Short Biography: My graduate training has been a slightly odd mixture of structural and computational biology & physical and analytical methods. I also know a thing or two about polymers. Go figure.

for the headsup / legup / input . . I've zoomed through the tutorial, and will catch up on the content-stuff another time hopefully soon. SquisherDa (talk) 01:14, 10 February 2012 (UTC)Reply

Beta amyloid

edit

Thank you for your note about 42. It would be nice to have an unambiguous definition of protein. Our definition, on Wikipedia, is still ambiguous, even after my edits. In other words, not any chain of aminoacids is a protein, but we do not have an unambiguous definition which allows us to distinguish between:

  1. a polypeptide which is also a protein and
  2. a polypeptide which is not a protein (i.e. a plain "peptide").

It would be nice if we could say that a protein is a polypeptide that is codified by DNA of some living organism, while a peptide is not (being for example the product of the degradation of a protein by means of a protease)... which would be unambiguous, but I cannot find this definition in the literature. If you want to discuss this, you can do it here. I am monitoring your page. Regards, Paolo.dL (talk) 13:14, 2 May 2014 (UTC)Reply

It's tricky, there really isn't any single clear definition in the literature to draw from. For instance "unstructured polypeptide" and "intrinsically disordered protein" basically mean the same thing. I think the most relevant parameter should be whether a polypeptide posses secondary and tertiary structure, unfortunately there are decades worth of conflicting definitions of "peptide" vs "protein" in the way of that. Also, for what it's worth small peptides can be genetically encoded too, so that doesn't really work either. (+)H3N-Protein\Chemist-CO2(-) 14:10, 2 May 2014 (UTC)Reply
Interesting. Thanks. Paolo.dL (talk) 15:00, 2 May 2014 (UTC)Reply
It's there. THe aim is preponderance of reliable secondary and tertiary sourcing. Take all the v good/classic grad texts you can—Branden and Tooze, Creighton, Fersht, Robert Copeland, Cantor and Schimmel, etc—read the relevant intro sections, and just write it. You'll get feedback. You two have the background. Cheers. Le Prof Leprof 7272 (talk) 01:46, 12 June 2014 (UTC)Reply

Re

Hi, i guess you are right with your edit summary, however, the main point were about the other edits, which you apparently reverted. Are you suggesting that oligopeptides, with only a few amino acids are also called polypeptides, which are defined to have many amino acids? prokaryotes (talk) 02:02, 18 August 2014 (UTC)Reply

The wording was a little odd, couldn't exactly tell what you were getting at as originally written. You're welcome to reinsert your edit with the revised terminology, but consider that you'd basically be writing "a polypeptide [..] can contain many peptide bonds", which does sound a little circular.

I've to admit that im learning chemistry as i go along, so sometimes errors such as these happen, especially when sources are scarce, thanks for your response. I will try to bring it more in line with this reference http://www.biology-online.org/dictionary/Polypeptide prokaryotes (talk) 02:15, 18 August 2014 (UTC)Reply

ArbCom elections are now open!

edit

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. It has the authority to enact binding solutions for disputes between editors, primarily related to serious behavioural issues that the community has been unable to resolve. This includes the ability to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail. If you wish to participate, you are welcome to review the candidates' statements and submit your choices on the voting page.
