Jessieee Posted January 21, 2005 Posted January 21, 2005 any way to test for the presence of hydroxylysine?! also what is the structure of hydroxylysine? do milk contains hydroxylysine!? and do any compound of hydroxylysine is harmful to human body!? lots of questions, thz alot~!!! =)
ed84c Posted January 21, 2005 Posted January 21, 2005 They put hydroxylysine compounds in Salt sometimes, as an additive, so I prosume at least not all of the compounds of it are toxic.
Jessieee Posted January 21, 2005 Author Posted January 21, 2005 so u mean some of them are toxic!? coz i am doing some experiments to find out whether the hydroxylysine in milk when heated will produce toxic stuffs, and seems this is related to fructose or sth.. wanna find out if this is true...
ed84c Posted January 21, 2005 Posted January 21, 2005 at least not all of them are toxic. i.e. what i mean is there is atleast 1 compound that isnt.

Gilded Posted January 21, 2005 Posted January 21, 2005 It's always good to have a normal version AND a Zim-version, but I prefer having them in the same post. "and seems this is related to fructose or sth.." The hydroxylysine's hydroxyl group can form a bond with some monosaccharides, at least.
ed84c Posted January 21, 2005 Posted January 21, 2005 There you go http://herkules.oulu.fi/isbn951427136X/html/x194.html Aparantly its in Collagen. What were you saying about the ZIM post gilded?
Silencer Posted January 21, 2005 Posted January 21, 2005 you double posted the same thing, except one is an image and the other is text.
ed84c Posted January 21, 2005 Posted January 21, 2005 no, i was quoting myself because Jessiee decided that infact all of them were toxic, based on what i said in post 2.
Gilded Posted January 21, 2005 Posted January 21, 2005 "http://herkules.oulu.fi/isbn951427136X/html/x194.html" Yay for Oulu University. Too bad Finnish scientists always seem to study booooring things like proteins.
Jessieee Posted January 22, 2005 Author Posted January 22, 2005 soo... is there any way to test for it?
budullewraagh Posted January 22, 2005 Posted January 22, 2005 amino acids should prove to be soluble in water but insoluble in ether if that helps you any. on a very oblique note, you could add a nitrite to a solution of the amino acid in water. if you notice NO2/N2O4 evolved, you can tell the solution is acidic. careful, though because those gases are highly toxic.
jdurg Posted January 22, 2005 Posted January 22, 2005 Yeah, NO2 and N2O4 aren't something you want to be ingesting in large quantities. However on the scale that you'd probably be doing this at, the amounts shouldn't be all that great. You'll know you're making the gas if you see the brown color of N2O4, or if the reaction area smells like you're stuck in traffic.
