The precise origins of the dimensions of US letter-size paper (8.5 × 11 in) are not known. The American Forest & Paper Association says that the standard US dimensions have their origin in the days of manual papermaking, the 11-inch length of the standard paper being about a quarter of "the average maximum stretch of an experienced vatman's arms".

[1] [2] The transducer in this system is a heterotrimeric G protein, composed of three subunits: a Gα protein such as G αq, and a complex of two tightly linked proteins called Gβ and Gγ in a Gβγ complex. [1] [2] When not stimulated by a receptor, Gα is bound to guanosine diphosphate (GDP) and to Gβγ to form the inactive G protein trimer.
