1·We had previously observed lower concentrations of some brain metabolites, markers of brain injury, in healthy non-alcohol dependent people with BMIs in the overweight to obese range.
我们之前在健康不酗酒的人群中选择bmi指数在超重和肥胖之间的，发现一些低浓度的脑部代谢物，这是脑损伤的标志。
2·The subjects also provided urine so the researchers could measure the amount of nicotine and its metabolites, like cotinine, for an objective record of their exposure to cigarette smoke.
这一项目中还包括尿检，因此研究人员还可以测量尿中尼古丁及其代谢物的含量（如可铁宁），这样会得到有关他们处于烟雾中时的情况的比较客观的记录。
3·Metabolomics studies metabolites, the by-products of the hundreds of thousands of chemical reactions that continuously go on in every cell of the human body.
代谢组学研究代谢物，即人体细胞内持续进行的成千上万化学反应的副产品。
4·Metabolites can be tricky to detect using techniques where the sample is dissolved and mixed with a matrix material before it can be analysed, since the metabolites often look similar to the matrix.
一些技术需将样品溶解并于基质混合后才能对样品进行分析，这样所得结果可能会与真实情况有出入，因为代谢物常常看上去就像基质。
5·These toxic substances from decay component by juice to decay component diffusion, which is not part of the same rotten rotten part containing microbial metabolites, particularly mycotoxins.
这些有毒物质可以从腐烂部分通过果汁向未腐烂部分扩散，使未腐烂部分同腐烂部分一样含有微生物的代谢物，尤其是真菌毒素。
