WebThis β-carotene is composed of approximately 50% all-trans (ATBC) and 50% 9-cis β-carotene isomers (Ben-Amotz & Fishier, 1998 ). It is hypothesized that the presence of 9-cis β-carotene minimizes the crystallization of ATBC, and therefore, their combined presence in the oily globule in the alga is crucial (Ben-Amotz, Lers, & Avron, 1988 ).
