The structure of a number of low‐molecular‐weight acidic peptides containing taurine prepared from calf brain synaptosomes and their subcellular vesicles was studied using electron impact mass spectrometry. At least seven sequences could be identified: N ‐acetylas‐partyl‐glutamyl‐taurine, N ‐acetylaspartyl‐taurine, N ‐ace‐tylglutamyl‐taurine, glutamyl‐taurine, aspartyl‐taurine, seryl‐glutamyl‐seryl‐taurine, and seryl‐taurine.
