The molecular receptive range (MRR) of a mammalian odorant receptor (OR) is the set of odorant structures that activate the OR. while the distribution of these odorant structures across odor space is the tuning breadth of the OR. Variation in tuning breadth is thought to be an important property of ORs. with the MRRs of these receptors varying from narrowly to broadly tuned. https://balboasurfandsstylers.shop/product-category/baja-hoodies/
