El azufre es un elemento químico de número atómico 16 y símbolo S (del latín sulphur). Es un no metal abundante con un color amarillo característico. Dicho elemento es generado en estrellas masivas en las que predominan temperaturas que provocan la fusión entre un núcleo de silicio y otro de helio en un proceso denominado nucleosíntesis de supernovas. El azufre se encuentra en forma nativa en regiones volcánicas y en sus formas reducidas formando sulfuros y o bien en sus formas oxidadas como sulfatos. Es un elemento químico esencial constituyente de los aminoácidos cisteina y metionina y, por consiguiente, necesario para la síntesis de proteínas presentes en todos los organismos vivos. Se usa principalmente como fertilizante, pero también en la fabricación de pólvora, laxantes, fósforos e insecticidas.
