reversible de-animation reactions. That ammonium citrate nitrogen is similarly incorporated into rabbit skeletal muscle has been confirmed by Newton and Perry2. They have further demonstrated that aspartic acid is a more active donor of the 6–NH2 group and that the enzymic activity is concentrated in the sarcoplasmic fraction of muscle.
Kalckar 和 Rittenberg1 观察到,给予大鼠的标记
柠檬酸铵的氮 15 出现在肌肉
腺嘌呤核苷酸的 6-NH2 组中,得出结论,这些核苷酸参与了非常快速的可逆去动画反应。Newton 和 Perry2 也证实了
柠檬酸铵氮也被类似地掺入到兔骨骼肌中。他们进一步证明
天冬氨酸是 6-NH2 基团更活跃的供体,并且酶活性集中在肌肉的肌浆部分。
