x1 is a biological compound/biomolecule/organic molecule (one sense) of type/substance x2, originating in life-form/organism x3.
Must be associated with or originating from a life-form or life-process, or be assumed to be so. There are no implications about its structure; thus, this term is broader than "organic compound" in the sense that it does not require the presence of carbon, hydrogen, or any halogens, but it is potentially narrower than such a term in the sense that the compound really should at least be typically or historically associated with life or produced thereby. See also: "mivyselkra" and "xumsle".
