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).
1 For proteins (Polypeptides), the monomers are amino acids. 2  For Nucleic acids (DNA/RNA), the monomers are nucleotides which is made of a pentose sugar, a nitrogenous base and a phosphate group.  For carbohydrates (Polysaccharides specifically and disaccharidesâdepends), the monomers are monosaccharides.
