nutrition : imidazole dipeptides / IDPs

 This is turning out to be an interesting group of molecules.

• histadine containing : most common in chicken, fish, and then other skeletal muscle meats
• antioxidant and pH buffering : "instant energy" end-user experience
• generally not saturated in humans, so there are benefits to eating it
• also some research linking these to Parkinson's Disease ( neural death in the Substantia Nigra associated with oxidative stress )

There are three of easy interest; only one is a commerciallycommon supplement

• carnosine :
• the common supplement is beta alanine, as carnosine is produced in humans, but beta alanine is usually the rate-limiting input
• anserine : 
• uncommon commercially
• balenine : 
• uncommon commercially
