Etymology: "Proteinous" is a plain formation: the noun "protein" with the adjective-forming suffix "-ous", meaning "full of" or "having the nature of." The base word "protein" was coined in 1838 by the Dutch chemist Gerardus Johannes Mulder, who proposed it from the Greek "proteios," meaning "of the first rank," a name chosen because he thought the substance was fundamental to life. "Protein" itself therefore carries a quiet claim about importance, and "proteinous" inherits that sense of substance-rich, essential matter. The suffix "-ous" comes from Latin "-osus," which gave English a large family of adjectives such as "fibrous" and "nervous." Attaching it to "protein" produced a word meaning, in effect, "consisting of or resembling protein," and it is used mainly in technical and scientific writing.
