Etymology: Toxalbumin is a compound built from two words with very different pedigrees. Its first part, "toxin," goes back to ancient Greek, where "toxon" meant a bow, and "toxa" meant arrows. Latin borrowed the idea as "toxicum," a poison used on arrowheads, and the notion of a poison-tipped weapon eventually gave us the modern sense of a harmful substance. The second part, "albumin," comes from Latin "albumen," meaning egg white, itself from "albus," white. Protein in egg white gave chemists their name for a whole family of soluble proteins. The term was first used around 1890 by the research chemists Ludwig Brieger and Sigmund Fraenkel, who needed a name for poisonous proteins produced by plants. Joining the two elements described exactly what they had found: a toxin whose chemical nature was protein, like the albumin in an egg.
