代谢
进行了一项实验,以评估含氯胆碱(CCC)在蛋鸡的蛋和肉中的代谢产物。将十只棕色蛋鸡随机分为两组,每组五只。一组提供不含(15)N-CCC的饲料,另一组在11天内接受含有100 ppm(15)N-CCC的饲料。收集蛋鸡的蛋和肉样本。将蛋黄和蛋白分离。从胸肉和大腿收集肉样。使用离子阱电喷雾电离质谱(ion trap-ESI-MS/MS)测量CCC的代谢产物。在蛋和肉中检测CCC或其代谢物,结果显示CCC代谢为胆碱。获得了m/z 104(胆碱)或105((15)N-胆碱)的相应MS/MS光谱,而在m/z 122(CCC)或123((15)N-CCC)处未检测到任何物质。这项研究的结果表明,CCC将在蛋鸡的组织中被代谢。
An experiment was conducted to evaluate the metabolic products of chlorocholine chloride (CCC) in eggs and meat of laying hens fed a diet containing (15)N-CCC. Ten brown laying hens were randomly divided into two groups of five each. One group was offered (15)N-CCC free diet while the other group received a diet with 100 ppm (15)N-CCC for 11 days. Samples of eggs and meat from the laying hens were collected. Egg yolks and albumen were separated. Meat was collected from the breast and femur. The metabolic products of CCC were measured using ion trap electrospray ionization mass spectrometry (ion trap-ESI-MS/MS). Determination of CCC or its metabolites in eggs and meat showed that CCC was metabolized to choline. Corresponding MS/MS spectra were obtained for m/z 104 (choline) or 105 ((15)N-choline), whereas nothing was detected at m/z 122 (CCC) or 123 ((15)N-CCC). The results from this study indicate that CCC will be metabolized in tissues of laying hens.
