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!!!
求助各位大神,现在想购买小分子数据库,求大神推荐。
我知道的免费的数据库有zinc
求推荐哪家公司或者研究所的小分子数据库可以购买,十分感谢!!!!!!
求助大家,小分子药物最新专利申请情况跟踪,之前听别人说可以在一个网站可以导出这个信息。
不知哪位大侠知道,告知一下,不胜感激!
就是蛋白质分子的小片断
是氨基酸形成的
一、首先你要明白肽是什么...........................肽是氨基酸通过酰胺键结合而成的东西.........
二、你要明白氨基酸是什么..........................氨基酸是构成蛋白质的基本单位,多种氨基酸结合为长肽链,几条长肽链再盘旋就形成了蛋白质......................
三、关于小分子肽、短肽、多肽、寡肽.......其实都是肽.......区别只是由多少个氨基酸构成而已............
所以,你的问题可以很粗暴地理解为“蛋白质对人体有没有副作用”.......
如果你营养足够的情况下,再补充这个,会导致营养过剩,从而加重身体代谢的负荷............类似就是这样子的了...........小分子肽,一般现在用于化妆品上比较多(一ye子.植物肽面膜就是这个).......小分子肽(可以简单理解为纳米胶原蛋白),这比蛋白质(也可以粗暴理解为胶原蛋白)更加容易吸收......而用在食品上,要视乎是何种小分子肽了.....大豆肽、花生肽、大米肽....不同的肽有不同的功效.......主要可以改善风味、改善吸收、增强胃肠道功能等等.......
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.
