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).
Just like in DNA, RNA is made of monomers called nucleotides. Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar called ribose, and a phosphate group. Each nitrogenous base in a nucleotide is attached to a sugar molecule, which is attached to one or more phosphate groups.
