Hello I did some Googling but can't seem to be able to figure this out. The difference between iso pentane and neo pentane is in the molecular structure, they both have 5 carbon atoms. 1. why is endorphin so different from neo endorphin? endorphin has nearly 3x the number of carbon atoms as neo-endorphin 2. what's the practical function of neo-endorphin and endorphin? which is the 'happy' chemical? 3. in terms of practical purpose, which is more important, alpha or beta endorphin? Thanks

hello all I am new here and I hope you can help me out. I tried to do some Googling but I can't find the answer to this. The difference between iso-pentane and neo-pentane is in the arrangement of the atoms, they are both 5 carbon atom, with different structure. 1.But why is endorphin so different from neo-endorphin? The former has about 3x the number of carbon atoms as neo-endorphin? 2. What's the the practical function of endorphin and neo-endorphin? Which is the one that makes us happy? 3. And in terms of practical purpose, which is the more important one, alpha or beta endorphin? Thanks!
