Summary
In normal human platelets twenty amino acids and additionally taurine, phosphoethanolamine
and phosphoserine were determined on a quantitative basis, using elution chromatography
on ion exchangers.
The highest molar share goes to taurine, glutamic acid, alanine, aspartic acid, proline
and serine. The other amino acids can be found in free form only in a low concentration
in platelets.
The connection of these results with other investigations on the metabolism is discussed.
