Retinol has that head group and not a carboxyl group so it cannot be given a standard lipid number. I think we're stuck denoting it one of two ways: either by its common name, or retinol, or its more formal IUPAC designation:Vitamin A and Carotenoids as Antioxidants in a Physiological Contex
Summary:
@Travis ("Retinol [], which contains 5 conjugated double bonds"..)
IUPAC ID: (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohex-1-enyl)nona-2,4,6,8-tetraen-1-ol
Which seems prolix, to be sure; but back in the time before Internet was Universal (circa < 1990, or < ~0 U.I. ), this name could could tell you how to draw the molecule having only a pencil and a piece of paper. So it's pretty amazing, really, as it defines a three dimensional line drawing with just words and numbers.
