Insect cells convert vitamin A into a number of retinoids that are evolutionarily conserved with those of mammalian cells. However, insect cells also produce additional natural retinoids. Namely, two retinoic acid peptides, N-trans-retinoylserine (1) and N-trans-retinoylalanine (2), have been isolated from a cell line of the common cabbage looper, Trichoplusia ni. These are the first examples of naturally occurring retinoic acid linked to amino acids through an amide bond; the amino acid moieties are depicted in the more common L-configuration, although the absolute configuration was not determined due to the minuscule sample amount.
