Carbon isotopic changes of 16 proteinogenic amino acids during trophic transfer in a cultured marine consumer

Abstract Stable carbon isotopic compositions of amino acids (δ 13CAA) in organisms potentially record information on carbon sources and flow in food webs. In this study, we report δ 13C values of 16 proteinogenic amino acids in marine consumers and evaluate their changes associated with the trophic...
