Due to advances in biochemistry and structural biology, we are nowadays very close to knowing in detail various receptors -primary, secondary, tertiary and even quaternary [in cases when there are subunits] structures- Moreover, molecular genetics allows us to get acquainted with the receptors natural variants polymorphisms and to analyze their functional relevance susceptibility and even resistance to several conditions.
Gracias a los avances en bioquímica y biología estructural hoy estamos muy cerca de conocer en detalle a los diversos receptores estructuras primaria, secundaria, terciaria e incluso cuaternaria, en los casos que hay subunidades.
