1. (a) There are two main types of adrenergic receptors: the a- and B-adrenoceptors. Noradrenaline shows slight selectivity for the a-adrenoceptor, whereas isoprenaline shows selectivity for the B-adrenoceptor. Adrenaline shows no selectivity and binds equally well to both the a- and B-adrenoceptors. Suggest an explanation for these differences in selectivity. OH OH OH Но, NH2 HO HO. Но Но HO Noradrenaline Isoprenaline Adrenaline (b) Isoprenaline undergoes metabolism to give the inactive metabolite shown below. Suggest why this metabolite does not bind to the B-adrenoceptor. OH H .N. Мео. но inactive metabolite of Isoprenaline

Applications of Molecular Spectroscopy

When light sources pass through the diffraction grating then light splits into different wavelengths. The light source produces two types of patterns that are shown as destructive and non-destructive. The light source is in the form of quanta that is quantitation.
