Glycemic response[edit]

Any information as to whether or not this substance causes a glycemic response (spikes your blood sugar) like sucrose, or if it attenuates this response? 0-0-0-Destruct-0 03:02, 24 October 2006 (UTC)

Good question - wish I could remember off the top of my head. Trehalase in the gut is the determining step for breakdown into glucose. Its on the villi. Deficiency is rare. It would be the question of rate of release. GraemeLeggett 08:41, 24 October 2006 (UTC)

I came to this page having eaten a snack product and read ingredients. I want to know about GI and if there were any other interactions. I had already guessed trehalose might be like maltose - hadn't remembered the term disaccharide at first, just knew maltose was rumoured to have higher gi than glucose due to delivering two glucose molecules at a time. The article mentions sweetness - but how is this connected to GI if at all? I also wondered about any evidence of other health risks - thinking of the heard-of mooting of diabetes-incidence risks of high fructose consumption. Mention here of water-holding properties made me think of glycerine - pregnant women and diabetics are advised caution with that. Not that I am diabetic.So who going to find the info and put it in? I think over all this article is written for undegraduate biochemists and commercial scientists, rather than the interested consumer. Can we do both? We're meant to avoid too much unexplained jargon, aren't we? (feel free to seperate those few last points into a new section - limited time here now).

Xerobiosis[edit]

Xerobiosis, Is this a real term? Googling it only brings forth two results, both of them mentioned in Wikipedia entries.--Hooperbloob 03:17, 5 Dec 2004 (UTC)

Added a bit of text based on my own memories of working with the stuff. GDL 1 Feb 2005

Haworth projection[edit]

Can we get this molecule in the haworth projection? Thanks! —The preceding unsigned comment was added by 139.62.210.57 (talk)

Done. Welcome to Wikipedia, by the way! Fvasconcellos (t·c) 18:58, 17 April 2007 (UTC)


Hi, I think the Haworth projection is incorrect. The 2nd sugar should be a-D-glucose but the stereochemistry is inverted. I'll see if I can fix it later unless someone else does it first. I'm not sure what the formating is though. See http://www.chem.qmul.ac.uk/iupac/2carb/36.html for an image of trehalos —Preceding unsigned comment added by 128.32.50.98 (talk) 00:16, 14 September 2007 (UTC)

Use in Plant Engineering[edit]

The gene for trehalose synthesis was inserted into plants (both chloroplast and nuclear engineering) to investigate use in drought resistance. Rather successful, though it had some effects on growth etc when inserted into nuclear genome. Worthy of addition, under "Biotech. Apps", or perhaps a simple mention?

The hayashibara stuff[edit]

Although it seems weird for the article to mention hayashibara in the lede and then not mention anything about it elsewhere, here's some (English language) references to Hayashibara's work on the stuff: [1] [2] --moof (talk) 08:51, 14 June 2009 (UTC)

this sounds more like advertisement rather that an encyclopedic info, especially because it is in the lead. --ArazZeynili (talk) 13:59, 6 February 2012 (UTC)

I still don't know if trehalose is good fom me the consumer> Is it? —Preceding unsigned comment added by 99.35.162.89 (talk) 20:25, 17 March 2010 (UTC)

Trehalase intolerance[edit]

There is evidence of Trehalase Intolerance, similar in symptoms to Lactose Intolerance, see http://www.ncbi.nlm.nih.gov/pubmed/11941647 and http://www.ncbi.nlm.nih.gov/pubmed/10522609 . Perhaps it should be mentioned also here? — Preceding unsigned comment added by 84.250.234.56 (talk) 15:07, 15 December 2011 (UTC)
