Water Channels in Cell Membranes

[parede2010]

would this channel become saturated similar to ion channels?

Yes, the rate of water permeation through this channel is limited and has been estimated to be on the order of 1 water molecule per nanosecond.

to think that this is one channel, where dozens if not hundreds exist in one cell, and we are made out of more then 100 billion cells. the amount of water molecules is staggering

A cada segundo, 1 bilhão de moléculas de água (vermelho e branco) passam por meio de uma aquaporina! Em branco são areas apolares e em verde areas polares. Em azul areas positivas e em vermelho negativas! Em amarelo destaca a passagem de apenas 1 molécula de agua.

I'm always astonished how we perceive our world in dimensions of meter, foot etc. yet we consist of so many many small units.... very amazing.

Do you have this video also in a bit better quality?

Anyway: Thanks for sharing this.

Click 'more info' in the area to the right of the movie above, and then the first link under 'Visit here for more information'. On that page you will see a link to an mpeg version under the youtube movie posted there.

wow this is way over my head... but still interesting good work!

[specularlobster]

your model is too good!

what program you use to perform de brownian movement?
