title: [Free amino acids and peptides in the muscles of 1- and 2-day-old cadavers].
abstract: High-voltage electrophoresis and the analytic procedure combination of high-voltage electrophoresis--paper chromatography were used for the analysis of protein-free extracts of muscle tissue in one-- to two--day old corpses. The protein-free extracts from both types of tissue specimen were found to contain also peptides in addition to free amino acids. The amino acids composition of isolated fractions is not mutually comparable. There were also differences as regards peptides. In the two--day corpse a new peptide appeared in the acid part and disappeared in the weak base part. The changes suggest that not only proteolysis but also peptidolysis are in progress on the second post-mortem day.
