Metoprolol loses beta-receptor selectivity at high doses and in poor metabolizers. If drug is administered for tachycardia secondary to pheochromocytoma, it should be given in combination with an alpha blocker (which should be started before metoprolol is started)
Best Answer: Amino Acids are the monomers that make up protein.... and enzymes are a type of protein. (i.e. the peptide chain is the polymer made of amino acid monomers). There may be a-helixes and b-sheets formed (secondary structure). This chain then folds (into tertiary).
The monomers of proteins are 20 different amino acids. Amino acids are made of a central carbon bonded to four groups: hydrogen (-H),amino group (-NH2),carboxyl group (-COOH) â¦ ,and some side chain symbolized by R. 9 people found this useful. Answered. In Biology.
