Novel a-acyl dipeptides of the formula: R.sup.2 --NH--CHR.sup.1 --O--AS in which AS, R.sup.1 and R.sup.2 have certain, more precisely defined meanings. These N-acyl dipeptides are more stable under conditions of sterilization (121.degree. C.) than corresponding, non-acylated dipeptides. On the other hand, they are cleaved more rapidly and more completely at the peptide bond in the living organism than the cleavage of the acyl group from simple N-acyl amino acids takes place. They can therefore be used with advantage as a source for the carbon terminal amino acid in mixtures and solutions for artificial nutrition or in culture media for cell cultures.
新颖的a-酰基二肽的化学式:R.sup.2 --NH--CHR.sup.1 --O--AS,其中AS、R.sup.1和R.sup.2具有特定、更精确定义的含义。这些N-酰基二肽在灭菌条件(121摄氏度)下比相应的非酰化二肽更稳定。另一方面,它们在活体内的肽键中被裂解得更快、更完全,比简单N-酰基氨基酸的酰基从中裂解的速度更快。因此,它们可以优先作为混合物和溶液中碳末端氨基酸的来源,用于人工营养或细胞培养基。
