WHAT DOES LSD VIAL MEAN?

In the LSD-bound crystal structure, the facet chain from the lid residue L209EL2 varieties in depth hydrophobic contacts with equally LSD and bordering residues in TMs III, IV, and V (Figure 4C). Once the lid moved aside to show the binding pocket in simulation, quite a few of such contacts broke. We Hence hypothesized that L209EL2 functions to be
