El reactivo, de color azul, cambia a violeta en presencia de protenas, y vira a rosa cuando se combina con polipptidos de cadena corta. El Hidrxido de Potasio no participa en la reaccin, pero proporciona el medio alcalino necesario para que tenga lugar. Son necesarias por lo menos dos uniones peptdicas para que tenga lugar la reaccin. La reaccin del biuret no es una reaccin especfica para protenas.
