L-sugars are found in nature. E. coli has a set of genes to utilize L-arabinose, which would be unlikely if it were only found synthetically.

L-arabinose is a common biopolymer component. i am removing the 'rare' comment from the main page Xcomradex 04:09, 9 June 2006 (UTC)Reply

Arab-inose...? edit

I'm curious about the origin of the name of this sugar, does it really has something to do with arabic sugar? —The preceding unsigned comment was added by 89.139.243.116 (talk) 17:36, 2 February 2007 (UTC).Reply

Maybe a sugar in Gum Arabic? BrotherSulayman (talk) 10:16, 6 May 2008 (UTC)Reply

likely misidentification of D versus L arabinose structural formulas edit

Someone should check the structural formulas given in the picture of the cyclic arabiofuranose on the left and the mirror-image Fischer projection formulas on the right. I believe the D and L identifications are reversed, so that the pictured furanose is L arabinofuranose, and the two Fischer formulas should be labeled L for the one on the left (which corresponds to the L arabinofuranose pictured) and D for the one on the right (which corresponds in structure to D glyceraldehyde). Cf articles on D Ribose and Glyceraldehyde. If I am correct here, both the picture files linked to this article should be relabeled with D and L interchanged. Then no editing of the article itself would be necessary.CharlesHBennett (talk) 01:11, 9 November 2010 (UTC)Reply

All the images currently used in the article appear to be correct to me. -- Ed (Edgar181) 17:01, 18 October 2011 (UTC)Reply
