Gerrit Jan Mulder (1802 - 1880) on proteine

    Mulder heated a series of albuminous substances (e.g., egg white, blood, milk solids, and plant gluten) with lye, and obtained a product that when neutralized produced a whitish precipitate. Analysis suggested that the product always contain  ~ 16% nitrogen,  no matter the source. He concluded that this 'root substance' was basic to all living organisms, and named it proteine, derived from a Greek word meaning first or primary, a term suggested by the Swedish chemist Berzelius.

HOMEWORK. Some texts derive the word Protein from the word Protean: why might you think so?
