Sea urchins are classified in the Phyllum, Class, and Order of Echinodermata, Crinoidea and Regularia. They have radially symmetrical bodies made of calcareous plates, Arnold (1968); Clark and Rowe (1971) and are exclusively bottom-living, occurring both on hard and soft bottom, Ebert (1982); George and Jennifer (1979). Some species of sea urchins e.g. Heliocidaris erythrogramma, Tripneustes gratilla and Pneustes ventricosus are used as food in some parts of the world such as, Japan, Australia, Korea and Barbados, Jones and Endean, (1976). Some species of sea urchins are poisonous e.g. Toxopneustespileolus, Diadema setosum. Immers (1961 b) and Ficg (1964) studied the protein synthesis of the female sea urchins. lwata and Natano(1981)and Miyachi et a1 (1984). have been working on protein of sea urchin characterization. In this work protein partition by using different salts is investigated. |
