3-甲基组氨酸(MH)的排出量虽然已被用作反映肌肉蛋白质降解程度的指标,但该指标未包括MH可以在肌肉中贮存这一重要影响因素。肌肉中的游离β-丙氨酸能与MH结合成二肽——鹅肌肽(balenine)。禽类的肌肉发达,为研究鹅肌肽对MH排出量的影响,选用自1日龄起即喂以谷类为主不含鱼和肉类的混合饲料的4、6、9、12和18周龄的雄雏鸡各3只,左胸皮下注射3-(~(14)CH_3)MH。随后每天收集排泄物,连续4
Although the amount of 3-methylhistidine (MH) excreted has been used as an indicator of the degree of muscle protein degradation, this indicator does not include the important influence that MH can store in muscle. The free beta-alanine in muscle binds to MH to form a dipeptide, balenine. In order to study the effect of goose carnosine on the discharge of MH, the muscle of poultry was selected. At the age of 4, 6, 9, 12 and 18 weeks old Three male chicks were injected with 3- (~ (14) CH_3) MH in the left subcutaneous injection. Then collect faeces every day for 4 consecutive days
