  rdf:value "Proteínas de la superficie celular que se unen a la epinefrina y/o norepinefrina con alta afinidad y que generan cambios intracelulares. Sus dos clases principales, la alfa y la beta, se diferenciaron originalmente por sus actividades celulares; sin embargo, en la actualidad se distinguen por su afinidad relativa por ligandos sintéticos característicos. Además, se pueden clasificar de acuerdo con los subtipos de proteínas G con los que se unen; en esta disposición no se realiza la distinción alfa-beta."@es, "Cell-surface proteins that bind epinephrine and/or norepinephrine with high affinity and trigger intracellular changes. The two major classes of adrenergic receptors, alpha and beta, were originally discriminated based on their cellular actions but now are distinguished by their relative affinity for characteristic synthetic ligands. Adrenergic receptors may also be classified according to the subtypes of G-proteins with which they bind; this scheme does not respect the alpha-beta distinction."@en ;
