group to the degree of sweetness of aspartyl dipeptides, we have synthesized a number of α-L-aspartyl dipeptides, such as the esters of α-L-aspartyl-L-hydroxynorleucine (16 and 17), -O-acyl-L-serine (18–21), -D-serine (22–28), -D-threonine (30–36), and -D-allothreonine (37–43); their sweetness potencies were compared with those of the corresponding dipeptides without a hydroxyl group. It has been found
为了评估羟基对天冬氨酰二肽甜度的贡献,我们合成了许多α-L-天冬氨酰二肽,例如α-L-天冬氨酰-L-羟基正亮氨酸的酯(16和17 )、-O-酰基-L-丝氨酸(18-21)、-D-丝氨酸(22-28)、-D-苏氨酸(30-36)和-D-异苏氨酸(37-43);将它们的甜味强度与不含羟基的相应二肽的甜味强度进行比较。已经发现羟基对α-L-天冬氨酰二肽酯的甜味有主要贡献。将羟基引入 LL 肽会产生效力降低的化合物。然而,在 L-D 肽中没有观察到这种规律;
