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).
A macromolecule is a very large molecule made up of smaller units called monomers. The monomers may be the same or slightly different. Macromolecules are formed by dehydration reactions in which water molecules are removed from the formation of bonds. Four main types of macromolecules control all activities. They are proteins, carbohydrates, nucleic acids and lipids. Their monomers are amino acids, sugars, nucleosides and glycerol and fatty acids.
