In the nudibranch Nembrotha Kubaryana, tetrapyrrole pigment 13 has been found to be a potent antimicrobial agent. The chlorophyll pigment is the most significant and essential pigments, as it plays a vital role in the biological process of photosynthesis. They also supplement photosynthetic pigments that absorb light energy in the blue region.In reef-building coral and sea anemones, they fluoresce; light is absorbed at one wavelength, and re-emitted at another. The primary function of pigments in plants is photosynthesis, which uses the green pigment chlorophyll and several colorful pigments that absorb as much light energy as possible. In many chromodrorid nudibranchs, they take in distasteful and toxic chemicals emitted from sponges and store them in their repugnatorial glands (located around the mantle edge). Carotenoids and photopigments both indirectly act as photo-protective pigments, as they quench oxygen free-radicals. Lycopene is the red pigment responsible for the color of tomatoes. When a pigment absorbs radiation, it is … The molecular structure of a pigment determines its absorption spectrum. Other essential plant pigments include anthocyanins, betalains, carotenoids, porphyrins and much more. For example, the amount of carotenoid a certain sea anemone decreases as we go deeper into the ocean. So whenever that amphipod eats the sponge, the chemical pigments prevents the moulting, and the amphipod eventually dies.Animals are incapable of making their own carotenoids and thus rely on plants for these pigments. There are two classes of pigments: black and brown insoluble eumelanins, which are derived from aerobic oxidation of tyrosine in the presence of tyrosinase, and the alkali-soluble phaeomelanins which range from a yellow to red brown color, arising from the deviation of the eumelanin pathway through the intervention of cysteine and/or glutathione. The compounds benzothiazole and tetrahydroisoquinoline ring systems act as UV-absorbing compounds.Coloration in invertebrates varies based on the depth, water temperature, food source, currents, geographic location, light exposure, and sedimentation. These pigments primarily absorb in the blue wavelengths, allowing the longer wavelengths to be scattered and producing the yellow color. Preys also protect themselves by their toxic compounds ranging from a variety of organic and inorganic compounds.There are several different types of melanins considering that they are an aggregate of smaller component molecules, such as nitrogen containing melanins.

Also in this creature, tamjamines A, B, C, E, and F has shown antimicrobial, antitumor, and immunosuppressive activities.The principal pigments responsible are:A variety of diseases and abnormal conditions that involve pigmentation are in humans and animals, either from absence of or loss of pigmentation or pigment cells, or from the excess production of pigment. Type A has carotenoids (chromogen) which are stoichiometrically associated with a simple protein (glycoprotein). The different types of chlorophyll pigments are:Pigments are the chemical substances, which exhibit wavelengths of the visible light, making them appear colourful. Several different melanins include melanoprotein (dark brown melanin that is stored in high concentrations in the ink sac of the cuttlefish Sepia Officianalis), echinoidea (found in sand dollars, and the hearts of sea urchins), holothuroidea (found in sea cucumbers), and ophiuroidea (found in brittle and snake stars).
