Study on the role of enzymic hydrolyzed peanut protein to the utilization of Pb～(2+)in vitro
Assimilated substance deriving from peanut protein assimilated by pepsin and trypsin in vitro as object,researched the correlation between soluble Pb2+ concentration and Pb2+,Ca2+,Fe2+ concentration.The amount of soluble protein in pepsin treatment following Pb2+ increasing show decreasing earlier then increasing,but show decreasing in trypsin treatment.Added Ca2+ decreased assimilated substance derived from trypsin and pepsin combining with Pb2+.Fe2+ promoted the combine capability between Pb2+ and pepsin assimilated substance,whereas Fe2+ decreased the combine capability between Pb2+ and trypsin assimilated substance.Results show combine capability between Pb2+ and assimilate substance derive from peanut protein assimilating by pepsin and trypsin in vitro correlated to Pb2+ concentration,added Ca2+ and Fe2+.The bound forms of plumbum are influenced by enzymic hydrolyzed peanut protein.
