Abstract:Seasonal variation in proximate,amino acid and fatty acid composition of the body wall of sea cucumber Apostichopus japonicus was evaluated.The proximate composition,except for ash content,changed significantly among seasons(P,0.05).Alanine,glycine,glutamic acid and asparagic acid were the most abundant amino acids.Total amino acid and essential amino acid contents both varied clearly with seasons(P,0.05).16:0 and 16:1n7 were the primary saturated fatty acid(SFA) and monounsaturated fatty acid(MUFA) respect...
Keywords:Apostichopus japonicus  proximate composition  amino acid  fatty acid
