MAKING molecules is easy for humans: within your body, billions of delicately balanced chemical processes are happening every day, moving groups of atoms around in shifting patterns.
As carbon-based life-forms, our internal chemistry is fantastically rich. Carbon can combine with other atoms so easily and in so many ways. It’s a toolbox that produces all of life as we know it. But we don’t know how most of these submicroscopic reactions work.
Natural molecular processes have evolved over billions of years, with complex pathways looping in dizzying complexity within the cell. These require sophisticated biochemistry to untangle.
