Isotope fractionation of fatty acids can reflect the metabolic pathway of fatty acids in organisms, but few studies have been conducted. In this study, stable carbon isotope fractionation of fatty acids in sea cucumber ( Apostichopus japonicus ) was conducted by feeding experiments of comparing the fatty acid profile and δ 13 C of fatty acids in body wall to diet. The results showed that the fractionation of δ 13 C of fatty acids in  A. japonicus  was −1.588–7.403‰. The fractionation of δ 13 C of saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), and polyunsaturated fatty acids (PUFAs) was 1.098–7.403‰, −1.588–2.778‰, and −1.559–5.614‰, respectively. The degree of fractionation of δ 13 C of SFAs was greater than that of unsaturated fatty acids (UFAs). We simulated the possible metabolic process of fatty acids in  A. japonicus  based on fatty acid profile and δ 13 C of fatty acids, indicating that the combination of these two methods could be potentially used in the study of fatty acid metabolism in marine benthic animal of  A. japonicus . Our finding provides a new technique for the metabolic pathways of biomolecules in organisms.
