No. Clothing and skin will block alpha, but not beta.
the beta blocker.
No. It is a beta-1 receptor blocker, and an inhibitor of angiotensin converting enzyme (ACE).
Noradrenaline has an amine group with a positive charge as well as two OH groups attached to its benzene ring. The amine group can form an ionic bond with the COOH group with aspartic acid residues in the receptor. Meanwhile, the OH groups can form hydrogen bonds with the OH groups of the serine residues in the receptor. These bonds will lead to noradrenaline binding with the beta receptor.
