Abstract
IN the course of isolating unidentified amino-compounds from bovine brain1–3, a substance was isolated from the neutral amino-acid fraction of the trichloroacetic acid of the brain, and was identified as 2-aminoethylphosphonic acid from the results of elementary analysis, infra-red spectrography and chromatography. The occurrence of 2-aminoethylphosphonic acid in protozoa4,5 and in the sea anemone6 has been reported both in free and combined form; but its presence in the higher animals has not been reported in either form until now.
