RESUMEN
The purpose of this study is to analyze the plasma proteins of physical education athletic and general students (aged 19-22) before their breakfast by two-dimensional electrophoresis.<BR>The results of this study, a protein which has not been found in any original report yet is detcted from physical education athletic students before breakfast.<BR>This protein was not detected from general studenets before breakfast. This protein was detected at the position of pI5.0, molecular weight of about 70, 000 on two-dimensional polyacrylamide gel electrophosis under non-denaturing codition, but it showed a molecular weight of about 30, 000 on SDS-polyacrylamide gel electrophoresis.<BR>As far as this research is concerned, neither special physical education athletic students and nor general students were observed in changes of two-dimensional electrophoretic patterns of blood cell cytosol and blood cell membrane proteins.
