Abstract
This study aims to investigate the profile of sterols and fatty acids of four species of molluscs (rock oyster bivalve; Saccostrea cuculate, clam bivalve; Callista umbonella and cylindrical clam; Solen vagina) and one edible snail species. (Ampullaria cuprina) and determining the best mollusc species of Qeshm beach has been designed. Mollusc species (100 each) were kept in cold boxes with ice and transferred to the laboratory, and the content of fatty acids and mollusk sterols were analyzed with the help of gas chromatography. The highest amount of myristic acid (14:0), lauric acid (12:0), pentadecanoic acid (15:0), heptadecanoic acid (17:0), stearic acid (18:0) and total saturated fatty acids in snail Edible and lowest myristic acid (14:0), palmitoleic acid (16:1), pentadecanoic acid (15:0), heptadecanoic acid (17:0) and stearic acid (18:0) in rock oyster bivalves was observed. The lowest amount of cholesterol and the highest amount of 5 and 12 stigmadranol, campastonol, stigma sterol, delta 7 campestrol and delta 5 onasterol were also observed in edible snail. This study emphasized the difference in the profile of sterols and fatty acids of four selected mollusk species, and the best profile of sterols and fatty acids was observed in the edible snail, which can be suggested for the production of various health products in the pharmaceutical and food industries.

Abstract
This study compares the antioxidant activity and phenolic content of extracts of four mollusk species (Oyster rock bivalve; Saccostrea cuculate, cabbage bivalve; Callista umbonella and Molok or cylindrical clam; Solen vagina and edible snail; Ampullaria cuprina) and determine the best mollusk in Qeshm coast. Mollusc species (n=100 for each mollusk) were stored in cold boxes with ice and transferred to the laboratory after collection. The samples were well ground and aqueous, ethanolic (90% ethanol) and hydro-ethanolic (50:50) extracts were prepared from them. The results showed that the highest amount of phenolic content (81.66 mg GAE/g extract), diphenylpicrylhydrazyl (DPPH) antiradical activity (1722.66 µmol Trolex /g extract) and antiradical activity equivalent to Trolex (649.33 µmol Trolex/g) extract) was observed in the ethanolic extract of edible snail. Also, the amount of antioxidant activity was maximum in three methods: PMP, 606.66 µmol Trolex, FRAP: (740 µmol iron/ gram of extract and RP: 1.24 in edible snail. Aqueous, ethanolic and hydro-ethanolic extracts of four Mollusca species showed different levels of antioxidant activity in all studied models. In general, ethanolic extract of edible snail showed the best antioxidant activity and phenolic content, which can be considered as rich sources of natural antioxidants for food usage is recommended
