A chemical compound formed by heating urea, containing two urea molecules joined by a carbon atom, used in protein detection tests.
From 'bi-' (two) + 'uret' (a variant of urea, from French 'urée'). The name reflects its structure of two urea units. Created in the 1800s by chemists studying urea decomposition.
The biuret test is a classic biology lab procedure—when you mix it with proteins, it turns purple or violet! This simple color change helps scientists identify and measure proteins in blood, milk, and other samples.
