SummaryIn 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.

The oxidation of 1 mmole of D-glucose 6-phosphate with 1.7 mmoles of lead tetraacetate admixed with 1.8 mmoles of sulfuric acid yields a preparation containing 0.77 mmole of D-erythrose 4-phosphate and 0.20 mmole of unoxidized glucose 6-phosphate. The D-erythrose 4-phosphate is separated from the D-glucose 6-phosphate by chromatography on Dowex 1-formate, and recovered as the barium salt of the hydrazone in 50% yield. Evidence is presented that erythrose 4-phosphate may exist in monomeric and dimeric forms. Glucose 6-phosphate and erythrose 4-phosphate produce different colors in the phenol – sulfuric acid reaction. This can be used for the qualitative identification and quantitative determination of these sugar phosphates.
