ACh travels across the synapse and binds with specialized ACh
receptor sites (AChR) on the postsynaptic muscle cell membrane, called the motor end plate.
(20) Second, the soy phytoestrogens do not go to the same
receptor site as Tamoxifen.
Molecularly imprinted polymers are a source of robust artificial
receptor sites.
Clearly this trend is consistent with the concept of a
receptor site that can accommodate molecules of the appropriate size, shape, and charge distribution, but molecular weight is a crude criterion because it does not take into account any aspect of the shape or charge distribution parameters.
Quinolinic acid works at the same
receptor site as glutamate, Young says.
Given any peptide, this can be achieved in two ways: (i) incorporation of multiple peptide copies to enhance affinity, or (ii) increase the number of radiometal ions per molecule bound at each
receptor site in vivo.
Given the research into the endogenous cannabinoid system with its huge
receptor site network, it is only natural to believe that these cannabinoids are vital to our health, vital to wellness, and support our largest self-regulatory system--the endogenous cannabinoid system."
There are not enough natural opioids produced, however, to compensate for the loss of
receptor site sensitivity caused by prior abuse of the opioid drug.
Because the side chain of salmeterol is anchored at the exosite, the active head portion continually attaches to and detaches from the
receptor site. This provides ongoing stimulation of the [beta] receptor and is the basis for the persistent duration of action of salmeterol.
Agonist-antagonists are opioids "that bind to the kappa opioid
receptor site acting as an agonist (capable of producing analgesia) and simultane- ously to the mu opioid
receptor site acting as an antagonist (reversing mu agonist effects)" (Pasero, Quinn, et al., 201 I, p.
extract competitively inhibited the binding of [[sup.3]H]MDL 105,519 to the glycine
receptor site (Figure 3).
This drug helps increase the contact time of the nerve messenger at the muscle
receptor site. This treatment will likely help your dog, but she may not have her normal endurance.
