Etymology: "Peptones" is the plural of "peptone," a term for a group of protein fragments produced when proteins are broken down by digestion or by enzymes. The name comes from ancient Greek, where "peptón" meant "cooked" or "digested," the past participle of "péptō," meaning "to soften, ripen, boil, cook, bake, or digest." The Greek verb is itself related to "péssō," meaning "to cook," so the idea of softening food by heat ran through its earliest uses. The word reached modern science by way of German, where "Pepton" was coined to name these digestion products. English then borrowed the German term directly, so the chemistry vocabulary draws on a Greek root that had long described cooking and digestion in everyday life, now given a precise technical sense.
