Amino acids in fowl seminal plasma

The free amino acids occurring in alcoholic extracts of fowl seminal plasma have been examined by filter-paper chromatography. Twenty-three have been detected consistently, and these include several that have not been hitherto reported in the seminal plasma of the domestic fowl. In addition, several unknown ninhydrin-reacting substances have been found. Glutathione and ergothioneine were not detected in the volumes of plasma chromatograhed. There was evidence of the presence of glycocyamine and an unknown imidazole compound.
