Long story short, I wanted to buy some miracle berries, due to their odd ability to change the flavour receptors on one's tongue. However, they're £15 for a packet of 10 tablets, PLUS postage and packaging. So, instead of just buying it, I looked it up and found that the active protein in miracle berries is called "Miraculin". A similar protein, Circulin also has the same effect. Now I want to find out how peptide bonds are formed in a laboratory, so that I can try and make some at home.
