The PSK peptide is present in dipteran species and can be seen by electron microscopy in their abdominal ganglia. PSK also activates Ca2+ influx into cells, which can lead to cell death. The PSK peptide is converted to cleavage products by enzymes, with bioassays being one way to measure these products.</p>

<p>Vasopressin is a peptide hormone that regulates water balance. It is synthesized in the hypothalamus and stored in the posterior pituitary gland, from where it is released when blood pressure falls.

This leads to a change in kinetic parameters for substrates, such as pravastatin and saquinavir. The binding site on bosentan may also be elucidated through monolayer experiments with efflux transporters.</p>

Sildenafil is synthesized from chrysanthemum morifolium, a plant also known as "shamrock." Sildenafil has been shown to have no effects on insulin resistance or lipid metabolism, but it does cause side effects such as headache, visual disturbances, and hearing loss.</p>
