主　　题：Corn peptide Bioactivity Plasma free amino acids 

摘      要：The effects of the ingestion of corn peptides with a low molecular weight(LMCP) prepared from zein on some plasma free amino acid concentrations in rats that had taken ethanol were investigated. LMCP(1 0 g/kg body weight) in 15% ethanol(10 mL/kg body weight) was given to Wister rats by intragastrical administration. The amino acid analysis showed that the concentrations of alanine, leucine, and proline in the plasma reached their maximum levels at 30 min for the LMCP-intake group. They are 582.39, 99.60 and 272.51 μg/L , respectively. But in the control group, the plasma free amino acid levels were not changed obviously. Therefore, LMCP could cause an increase in concentration of some free amino acids such as alanine, leucine and proline etc . in plasma of the rats that have taken ethanol.
