“…Through this metabolic conversion, antioxidative activities such as singlet oxygen quenching, scavenging of hydroxy radicals, and inhibition of lipid peroxidation of carotenoids are increased. Mytiloxanthin showed almost the same excellent antioxidative activity as that of astaxanthin [13]. Therefore, it was concluded that marine animals metabolize dietary carotenoids to a more active antioxidative form and accumulate them in their bodies and reproductive organs.…”

Carotenoids are tetraterpene pigments that are distributed in photosynthetic bacteria, some species of archaea and fungi, algae, plants, and animals. About 850 naturally occurring carotenoids had been reported up until 2018. Photosynthetic bacteria, fungi, algae, and plants can synthesize carotenoids de novo. Carotenoids are essential pigments in photosynthetic organs along with chlorophylls. Carotenoids also act as photo-protectors, antioxidants, color attractants, and precursors of plant hormones in non-photosynthetic organs of plants. Animals cannot synthesize carotenoids de novo, and so those found in animals are either directly accumulated from food or partly modified through metabolic reactions. So, animal carotenoids show structural diversity. Carotenoids in animals play important roles such precursors of vitamin A, photo-protectors, antioxidants, enhancers of immunity, and contributors to reproduction. In the present review, I describe the structural diversity, function, biosyntheses, and metabolism of natural carotenoids.

Since the early 20th century, a number of active natural pigments have been identified from marine sources, especially algae and marine microorganisms. This review presents 81 marine pigments, covering over 90 % known natural marine pigments. The objective of this article is to provide an overview on the types of pigments, their structural characterization, origins and biological functions that make them unique. We divide the major categories of pigments by chemical structure, either as carotenoids, indole derivatives (quinones and violacein), alkaloids (prodiginines and tambjamines), polyenes, macrolides, peptides, or terpenoids. Many of these pigments have a variety of biological activities, including antitumor, antibacterial, antioxidant and anti‐inflammatory. In addition, we discuss the development of biotechnology, and the contribution and utilization of marine natural pigments and the potential applications in the field of pharmaceutical research.

In the Okhotsk Sea, Halocynthia aurantium caught along with scallops have been discarded as bycatch. In order to avoid discarding H. aurantium and promote its use as a process material, we analyzed the proximate composition and carotenoids composition in its muscle. We also investigated the relationship between composition change in the muscle and gonad maturity. The results showed the following: (1) From summer to autumn, the moisture and ash contents decreased gradually; in contrast, the protein, lipid, and glycogen contents increased. (2) The protein, lipid, and glycogen contents showed a negative correlation with moisture.
