Acesso em:.1809-4392https://repositorio.ufpa.br/handle/2011/4521In this study, size exclusion chromatography (SEC) with ultraviolet (UV) and graphite furnace atomic absorption spectrometry (GF AAS) off-line detection was used to investigate the association of copper to high molecular weight (HMW) and low molecular weight (LMW) species present in Euterpe oleracea Mart. pulp. Total concentration of copper was 10.5 µg g-1. Copper was found to be associated to fractions corresponding to 28.7, 2.6 and 0.43 kDa.porAcesso AbertoMetalSECGF AASProteínasEuterpe oleracea Mart.ProteinsAvaliação da distribuição de cobre associado a compostos de diferentes massas moleculares na polpa de açaíEvaluation of the distribution of copper associated to compounds of different molecular weights in the acai pulpArtigo de Periódicohttp://dx.doi.org/10.1590/S0044-59672012000200016
