When somebody, especially not a chemist, talks about amino acids they typically mean the food additives what bodybuilders use for growing their muscles. But our, chemists, view is absolutely different and under amino acids we see molecules that cannot be bought in a drugstore. Our amino acids help pump the main “muscle” of any researcher - the brain! We have over 1.5 million different amino acids on Chemspace and we selected the most beautiful ones for this week! For example, the first one is a photochemically obtained proline analogue. The other six molecules will also make the researchers’ heart beat more often and the researchers’ mind to go and get them!
