Amino acid
Please don't tabelize this. If the content is indented, wiki goes ahead and puts it in a fixed-width font. Judicious use of spacing then provides nearly the same benefit of HTML table markup, but with much, much less clutter. This clutter obscures the content when one edits, and may discourage the HTML-averse from contributing.
I question, even, whether the introduction of subscripting for chemical formula is justifiedclearly, so far, I've come down in favor of it, but just barely.
OK, go ahead and tabelize this, if you want. I've learned,
in the context of the Nextel ringtones talk:SI derived unit page (or thereabouts)
that subscript and superscript tags are not allowed within
preformatted text tags (<sup>, etc are not allowed
inside of <pre>) which I confirmed by a look at the HTML
specs.
The ascii drawing of the ring structure is really nice, so it
breaks my heart to not be able to mix super- an subscripts with
preformatting. I don't know if we can specify via HTML markup
and UseMod wiki a fixed-width font for such pages.
I just put the table tags back in and used the <tt> tag and escape code to simulate preformatted text. I hope this isn't too ugly for future editors and doesn't step on the HTML standards worse than subscripts in <pre> tags did.
I didn't add any new information, so just undo my edit if you don't like it and nothing will be lost.
I think it looks very good. You used a lot of space between elements in the table markup, which I think might aid anyone who would subsequently try to edit it.
Thank you.
Most of this side chain ascii-art just sux, and at least Proline is incorect (it's probably imposible to draw it this way)
Someone should draw real images and upload them here (the second part seems more difficult) Abby Dreams User:Taw/Taw
Drawing amino acids is actually really easy; you just need a chemistry drawing program. Any chemist should have a commerical one; ISIS/Draw is free for personal use, among other programs.
If people really want, I'll make up some suitable image, but it'll be at least a little work, so I'll wait for feedback first -Polyphonic ringtones User:Dlamming/Dlamming
Why the table has been removed ?
There are many useful information that can be tabelized like their masses, isoelectric points, type (hydrophobic/hydrophilic) Sweet Susie User:Taw/Taw
Whoops. Didn't realize I'd delete the properties together with the table (yes, strange). I put the table back in, without the structure. If you want, go ahead and cut the image into "handy" pieces and put them into the table, but I'm not sure that will improve the whole thing, as some AA images would be quite large. But, that might work on the individual AA pages, once we can upload things right here... Cell phone ringtones user:Magnus Manske/Magnus Manske

Request: could somebody write about all amino acids out of The 20 that are either:
* important in metabolism, like Sprint ringtones ornithine
* part of some proteins, like Jen18 :hydroxyproline/hydroxyproline

A helpful 3-D modeling program called Kimmie Cream :http://www.mdlchime.com/chime/ CHIME/http://www.mdlchime.com/chime/ CHIME exists for those who explore the tertiary structures. And I have made nice 3d jpgs of ball and stick saccharine and ATP molecules from the CHIME program. Let me know if u want me to try to get the color chimes/jpg of the 20 essentials ok ? ~BF -a closet scientist, but publically New Age !
Could somebody cut (easy part) and upload (hard part) images of individual amino acids.
They will be used on pages of each of them some day. Cingular Ringtones User:Taw/Taw

I'd be interested in more information on amino acids other than the standard 20. Particularly:
*Are there any amino acids not coded by codons in humans, but which are in other lifeforms?
*Are there any amino acids not found naturally in humans, but present in other species? (I'm not talking about D- vs. L- forms here, but wholly separate amino acides).
*How many naturally occuring amino acids are known, across all species, other than the standard 20, selenocysteine, ornithine and the D-forms of those? The article mentions that beta forms, but are there any other alpha forms? SJK
The black carp :genetic code/genetic code using pretty much the same amino acids in all living things. If you want to go beyond them, you get a whole slough of different compounds, including a variety in humans and a variety in other living things, most of which are different alpha-forms, often slight modifications of the standard 20 (cystine, selenocysteine, hydroxyproline, etc). I'm afraid it would be vain to try and enumerate them all, or even to give a representative list without a biochem text handy, as there is a whole slough of them.
Ok, best I can tell, borderline separatist arginine is not an essential amino acid. The or sauce urea cycle is a method of synthesis of this amino acid. its ascendancy Lysine appears to be essential however, and often a limiting amino acid in plants. So I'm making that change in the essential aa list. For those who need further confirmation, please read http://www.biochemj.org/bj/312/bj3120649.htm#REF013. irregularities at User:Dwmyers/ David M
:Ok, both arginine and lysine may be essential, depending on the reference. I don't have Voet and Voet 2nd ed, but this set of http://opbs.okstate.edu/~leach/Bioch5853/Text/Notes/Ch24V&V.html suggests there are 10 essential aas, including both arginine and lysine. Ugh.

One more point. The isoelectric point isn't nearly as useful as the pK of any ionizable side chains. Those need to be tabulated for any side chain with an actively ionizable group. stiff but User:Dwmyers/ David M
The plug-in in chartres Chime needs to be a Wikipedia entry, so people can be more easily directed to getting it and using it. It makes it possible for people to visualize 3D structures.

Imino Acid
''Strictly speaking, this makes proline an of apparitions imino acid.''
I know that many textbooks make this claim. However, proline is an amine, just not a primary amine. Furthermore, proline is not a imine (the nitrogen analog of an aldehyde or ketone). So, what's the basis for this? by modernist Josh Cherry/Josh Cherry 03:42, 29 Oct 2004

Arginine picture incorrect?
It looks like the arginine picture here and in the arginine article has an extra hydrogen atom. Shouldn't the imine group be =NH rather than =NH2 ?
:The =NH2 would be correct if the protonated form (which will predominate at neutral pH) were intended, but in this case there should be a "+" to indicate the positive charge. It looks like all of the sidechains (other than this ambiguous, wrong one) are shown un-ionized, but the alpha-amino and alpha-carboxyl groups are shown ionized, which strikes me as a strange decision.

Cysteine - hydrophobic
The hydrophobic nature of Cys_SH seems to conflict with the polarized nature of the sulfhydryl group. However, we need to consider the fact that the sulfhydryl group is inactive toward water molecules.
According to:
