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).
Enzymes are made up of Î±n amino acids which are linked together via amide (peptide) bonds in a linear chain. This is the primary structure. The resulting amino acid chain is called a polypeptide or protein. The specific order of amino acids in the protein is encoded by the DNA sequence of the corresponding gene.
