Many factors are known to influence trace element metabolism and one of them is dietary protein. The present study examines the effects of casein, soybean protein, and peanut protein on the metabolism of the Zn, Cu, Fe, and Mn in growing rats. The results showed that Zn, Fe, and Mn excretions in the feces of peanut protein-fed rats (PPERs) were similar to(More)
Orthogonal experiment was applied to optimize the water extraction parameters of zinc from Flammulina velutipes, and then the extracts were separated by membrane filter (0.45 μm) and D101 macroporous resin. Six different species of Zn were obtained and the Zn content of various species were determined by flame atomic absorption spectrometry. The optimized(More)
The Surrounding Analysis Method¿SAM¿in thermodynamics was founded by professor Chen Guitang of Jilin University. It is a new distinctive course theory system, which is found on the recent knowledge. The SAM is not only due to Professor Chen’s long-term teaching experience in thermodynamics, but also due to his thorough study for every classical(More)
The Surrounding Analysis Method called the SAM is a kind of advanced classical thermodynamics theoretical system. The SAM is found on the recent research about the nature of object and the principle of conversion of energy. It studies the equilibrium of system and the changing course of state from root causes called inner cause and outer causes. A more(More)
