Ed Ranks Tachykinin Peptides

The graphics in the first Katamari Damacy game haven't aged well.

I, like every other decent American, would like for SOMEONE to finally make a definitive ranking of Tachykinins, which are (obviously) one of the largest families of neuropeptides with an ability to rapidly induce contraction of gut tissue.  Well, we are the change we seek. I can't just wait around all my life for someone else to do this. It's time to put up or shut up. And so I will do it.

You're welcome.

5. Kassinin - If you like disgusting, gross Tachykinin peptides derived from the nasty-ass Sub-Saharan Kassina frogs, then this is your peptide. But of course you don't like frog peptides. Those are the worst.

4. Neurokinin B - Wishes it could have been an Neurokinin A. But, alas, it never had that Asian Tiger Mom to help instill the fear it needed to succeed.

3. Neurokinin A - A deeply important part of mammalian nervous systems, not to mention it's also influential on mammalian inflammatory and pain responses. So this one is obviously cool, right?

2. Eledoisin - This one is cool so long as you keep pretending that it's some type of Star Trek alien species name and disregard the fact that it's a un-deca-peptide (i.e. it has 11 amino acid units) of mollusk origin.

1. Substance P - Substance P. Wow! What a name. This should clearly be some sort of magical formula used in comic books to give people powers or something. I really know nothing about science.
