Gas-liquid chromatography of free amino acids in the hyaloplasm of rat cerebral, cerebellar and ocular tissues, and in skeletal and heart muscle.

The paper deals with the composition of amino acids in the hyaloplasm of cerebral tissue, cerebellum, eyeball, heart muscle and skeletal muscles. The investigations performed showed that: the most numerous groups of peaks were obtained from heart muscle (45), cerebellar tissue (43), skeletal muscle (36), eyeball (29) and cerebral tissue (25); and the highest molar levels corresponded to those of tryptophan in skeletal muscle, heart and cerebellum, proline in the heart, valine in the eyeball, and aspartic acid in the brain. Weight ratios indicated high contents of histidine, tyrosine and phenylalanine in the tissues of the skeletal muscles, the heart and cerebellum.
