“…The 6-epiheteroxanthin 234 , corbiculaxanthin-3′-acetate 235 and corbiculaxanthin 236 isolated from these species were not reported previously from other shellfishes (Maoka, Fujiwara, Hashimoto, & Akimoto, 2005). A series of fucoxanthin 237 – 242 and fucoxanthinol 243 – 244 fatty acid esters were identified from M. chinensis (Chinese surf clam) ( Maoka, Fujiwara, Hashimoto, & Akimoto, 2007 ), R. philippinarum and M. petechialis ( Maoka, Akimoto, Murakoshi, Sugiyama, & Nishino, 2010 ). Amarouciaxanthin A 245 and its ester derivatives were identified from Paphia amabills and P. amabillis along with C37-skeletal carotenoids 246 – 249 ( Maoka, Akimoto, Yim, Hosokawa, & Miyashita, 2008 ).…”

“…Fucoxanthin 3-ester ( 32 ) and fucoxanthinol 3-ester ( 33 ) were found to be major carotenoids in Mactra chinensis [18], Ruditapes philippinarum , and Meretrix petechialis [19] . Amarouciaxanthin A ( 34 ) and its ester were also identified as major carotenoids in Paphia amabills and Paphia amabillis [20].…”

Marine animals contain various carotenoids that show structural diversity. These marine animals accumulate carotenoids from foods such as algae and other animals and modify them through metabolic reactions. Many of the carotenoids present in marine animals are metabolites of β-carotene, fucoxanthin, peridinin, diatoxanthin, alloxanthin, and astaxanthin, etc. Carotenoids found in these animals provide the food chain as well as metabolic pathways. In the present review, I will describe marine animal carotenoids from natural product chemistry, metabolism, food chain, and chemosystematic viewpoints, and also describe new structural carotenoids isolated from marine animals over the last decade.

“…Interestingly, most xanthophylls that accumulate in chromoplasts are esterified by fatty acid, rather than existing as free‐form (non‐esterified) xanthophylls, due to the presence of hydroxyl (–OH) groups, which are susceptible to esterification (Minguez‐Mosquera and Hornero‐Mendez, ; Hornero‐Mendez and Minguez‐Mosquera, ). Carotenoid esters are usually abundant in colored plant organs, such as petals and fruits, but they are also widely distributed in animals, occurring in marine shellfish and human skin (Wingerath et al ., ; Maoka et al ., ; Maoka, ). However, the molecular mechanism by which xanthophylls are esterified is unknown.…”

SUMMARYXanthophylls, the pigments responsible for yellow to red coloration, are naturally occurring carotenoid compounds in many colored tissues of plants. These pigments are esterified within the chromoplast; however, little is known about the mechanisms underlying their accumulation in flower organs. In this study, we characterized two allelic tomato (Solanum lycopersicum L.) mutants, pale yellow petal (pyp) 1-1 and pyp1-2, that have reduced yellow color intensity in the petals and anthers due to loss-of-function mutations. Carotenoid analyses showed that the yellow flower organs of wild-type tomato contained high levels of xanthophylls that largely consisted of neoxanthin and violaxanthin esterified with myristic and/or palmitic acids. Functional disruption of PYP1 resulted in loss of xanthophyll esters, which was associated with a reduction in the total carotenoid content and disruption of normal chromoplast development. These findings suggest that xanthophyll esterification promotes the sequestration of carotenoids in the chromoplast and that accumulation of these esters is important for normal chromoplast development. Next-generation sequencing coupled with map-based positional cloning identified the mutant alleles responsible for the pyp1 phenotype. PYP1 most likely encodes a carotenoid modifying protein that plays a vital role in the production of xanthophyll esters in tomato anthers and petals. Our results provide insight into the molecular mechanism underlying the production of xanthophyll esters in higher plants, thereby shedding light on a longstanding mystery.
