A new beta-aspartyl dipeptide, N-beta-L-aspartyl-L-phenylalanine (beta-AP), has been isolated and identified in urine and plasma from normal human volunteers. beta-AP was isolated from urine samples by high performance liquid chromatography (HPLC). Its identity and stereochemistry were demonstrated by HPLC and...
