Dear Steemian, Hopefully everyone still health to read STEM Content on steemit, In this opportunity i would like to share you some chemical pigment of Natural beauty from under the sea.

The Colors of Algae

Natural beauty is not only in the plains like the mountains but it also occurs under the sea, one example of natural beauty of undersea is the seaweed. Several people consider the seaweed as ordinary grass that was generally green, but the seaweed has an interesting color and contains different chemical compound. The chemical compounds contained in the seaweed is a natural pigment that produces the color of the seaweed. The seaweed is part of the macroscopic algae that grows attached to corals or rocks under the sea, the body part of this algae resembles a rod that called as Thallus. Based on the constituent pigment, the seaweed was classified into 3 groups, Chlorophyta (green seaweed), Rhodophyta (red seawed), Phaeophyta (chohcholate seaweed). Generally, the seaweed was green because the dominance of the pigment contained is chlorophyll, for example is Enteromorpha sp which is commonly used in Japanese food making.

Source of Pigment

Some of other pigments contained in seaweed is ficoeritrine that make the seaweed be Rhodophyta , and it also contains chemical compounds such as α-carotene and lutien that used as food preparation materials. Desides Rhodophyta and Phaeophyta there are also a golden yellow seaweed, the color is due to the lack of chlorophyll pigment contained therein, so that it looks golden yellow called as Chrysophytae and therein contain a compounds of β-carotene. The pigment compounds of seaweed could react through photosynthesis and biochemistry into photochemical that are beneficial for human health, the caratenoids of these algae can compile the light of photosynthesis process against free radicals or anti oxidants. In addition, the seaweed can be used as natural dyes and supplements in pharmaceuticals.

The Colorful of Other Species

The colorful of under the sea is not only found in algae plants but the event also occurs in some species of animals under the sea, The researchers have conducted a research in an Atlantic Ocean, they dive with a ROV (Remotely Operated Vehicle) engine that capable for operating at a depth of 3600 meters in an Atlantic ocean, they were found a worm species that has a transparent body (holothurian) that emit colorful in the dark at 2500 meters depth, the worm has a colors variety, from bright to transparent. Some of worms have emitted purple, red and white lights at a depth of 2700 m, these species generally has a strange shape and it shows some of lost evolution between vertebrates and invertebrates species. Several things still accelerate the experts about how these species acquires food. Some of scientists think they are creeping slowly, and can move quickly to get food. Therefore, the they still researching to obtain the knowledge of this species.

Conclusion 

---

The color emerging from algae is the influence of different pigments and chemical compositions, algae containing alpha and beta chemical compounds such as α-carotene and β-carotene that generally work on the  chemical photosynthesis process which is used for the manufacture of medicine or supplements. While the color of the underwater animals mentioned above is still in the further research, whether the pigment or chemical composition of the species resembles algae or not, or whether the process of light emission of this worm resembles of fireflies light emission, it is still being studied further by scientists.
