I need to figure out exactly how melting points of different polymers differ, in terms of their length and chemical makeup. if there is some sort of correlation between how much the melting point goes up with the addition of a single additional carbon to the chain, or if double bonds or more opportunities for hydrogen bonding, then that can also be used. any ideas would be great, thank you!

I need to get a list of the foods that can help making serotonin.

I am already aware of the 5-htp is the precurser of the serotonin... so what I want to know is the food or vitamins that we can easily find and eat from out everyday lives.

I think someone said, the green salads and some fruits can help make me serotonin. Is it true?

What else do you recommend?

Thank you.
