五千万个西湖 Fifty Million Westlakes

如果一个蛋白是一滴水,那么我们每个人的体内,都蕴藏着五千万个西湖。
If we see a protein as a tiny drop of water, then each one of us amounts to fifty million westlakes.

一个人~5E13细胞 (Google)
A man ~ 5E13 cells

一个人~2E4种蛋白 (Swissprot)
A man ~ 2E4 types of proteins

每个细胞每种蛋白拷贝数中位值 1.8E4 (PMID22068331)
Median value of copy number per protein per cell = 1.8E4

一个拷贝~一滴水(0.04ml)~2.8E-15西湖
One copy ~ One waterdrop (0.04ml) ~ 2.8E-15 Westlakes

Thus
一个人~1.8E22蛋白拷贝~5E7西湖
A man ~ 1.8E22 protein copies ~ 5E7 Westlakes

  1. 非常棒的比喻!上周您也用地球做了类比;期待梁老师的下一次公开讲堂。
