就是蛋白质分子的小片断
是氨基酸形成的
求助各位前辈,我最近在合成的化合物水溶性很好,非常好,以至于可以随便溶解在水里,它的六氟磷酸盐也可以随意溶解在水里(大于50uM),细胞成像实验显示它根本进不去细胞,求问有没有啥方法包裹一下让它进去?我搜了一下文献,感觉多数是把脂溶性特别好的东西包裹一下弄进去的,也许是搜索姿势不对没找到我需要的答案,**点拨啊!!!
如题,之前没做过药代,老师给了一个600+Da的五肽,想测下药代动参数,看文献推荐上述两种方法,但是不知道选哪种更好,lcms前处理会不会影响小肽。
有机的是有机化合物的简称,它指的是含碳化合物.
但是,有四大类常见物质一般不作为有机物处理:
1、碳的氧化物,如CO和CO2.
2、碳酸及其盐,如CaCO3.
3、金属碳化物,如CaC2.
4、拟卤素及其化合物,如(CN)2与KSCN.
水的化学式为H2O,它不含有碳元素,故不是有机物.
但若所描述的水不是化学意义的水,而是自然界存在的天然水,那么,水中会溶有一定量的有机物.
