carlito-cool55Participanta student heats up a test tube containing large amount of protien and biuret reagent. She notices a colour change from violet to blue. Explain why heating causes a colour change.

Becouse there is chemical reaction at the hight temperuture, and reagent bind to protein, that give new color (by the way – chang from violet to blue is a slight color change, becose those colorse is close to one another at the spectrum)

Everyone is entitled to their own nickname as long as it respects the forum rules. And really now, ghandi once said "Only speak if you can improve on the silence"

I use biuret regularly and never use heat to facilitate the reaction – is that weird?
