Terminology

edit

Why "re" and "si"? Do they come from names for the notes of the musical scale? (In the US, we use "re" for the note above "do," and "si" for the semitone above "sol," which we usually pronounce "so.") Unfree (talk) 15:48, 6 December 2008 (UTC)Reply

  • No same is in regular chirality Re (Latin rectus meaning right) and Si (Latin Sinister meaning left) V8rik (talk) 21:15, 6 December 2008 (UTC)Reply
  • The note above "so" is "la", and "ti" is the note above that (not "si") and it is not a demi-tone above, but a full two tones above, as in the song "Do-re-mi" from the Sound of Music with the lines "'So', a needle pulling thread. 'La', the note that follows 'so'. 'Ti', the drink with jam and bread. And we all go back to 'do', oh, oh, oh...." Musically yours. Pgpotvin (talk) 03:33, 10 January 2009 (UTC)Reply

Graphic

edit

I believe the graphic on this page is incorrect since it includes an unspecified r group. That needs to be defined. If the r group is a carbon, then the faces are correctly labeled. If the r group is Sulfur, as in acetyl-CoA, the faces are mislabeled. 66.168.27.4 (talk) 14:02, 12 September 2010 (UTC)Reply

decreasing CIP numbers

edit

the sentence about the decreasing CIP numbers is a bit ambigious (at least to non native speakers). Does this mean the CIP numbers are counted in decreasing order (from 3 down to 1) to determine if the rotation is clockwise or counter clockwise? — Preceding unsigned comment added by 131.234.78.232 (talk) 08:53, 13 August 2013 (UTC)Reply

That's exactly what it means, yes. Tomásdearg92 (talk) 20:35, 11 April 2014 (UTC)Reply
