so even small failures of repair would accumulate into chaos

The catechol ring with its two hydroxyl groups gives the molecule its name and its rapid metabolism: catechol-O-methyltransferase and monoamine oxidase clear it from circulation within minutes

Every voluntary movement, every heartbeat, every smooth muscle contraction in the gut traces back to a myosin head pulling on actin. The protein is so old and so universally conserved that almost every eukaryotic cell carries some version of it. The Science of Myosin Myosin II is the family member responsible for muscle contraction. Each molecule is a
