Portulacaxanthin II is involved in betaxanthin biosynthesis (via dopaxanthin) pathway. This pathway demonstrates the formation of betaxanthins such as portulacaxanthin II and dopaxanthin by means of non-enzymatic condensation from the amino acids L-tyrosine and L-DOPA, respectively. Tyrosinases have been described as capable to use those betaxanthins [ GandiaHerr05a ] as substrates for further metabolization. [HMDB]. Portulacaxanthin II is found in many foods, some of which are pineappple sage, peppermint, japanese pumpkin, and medlar.
