smhjn17 Posted November 20, 2015 Share Posted November 20, 2015 The skeleton of spider's silk is protein, right ?... But on testing a water sol. Of it with ninhydrin and biuret reagent no reaction is observed! How could this happen? Link to comment Share on other sites More sharing options...
BabcockHall Posted November 20, 2015 Share Posted November 20, 2015 What makes you think that spider's web protein is water soluble? With what does ninhydrin react? Link to comment Share on other sites More sharing options...
John Cuthber Posted November 21, 2015 Share Posted November 21, 2015 Ninhydrin reacts (at best) with one end of the protein chain. If silk is a long chain (and it is) and the "end" is buried in the middle of the fibre, what would the reagent reacts with? 1 Link to comment Share on other sites More sharing options...
