calcium chloride (CaCl 2), a granular white chemical with an unpleasant taste. It is used in a concentrated solution of the chloride salt of calcium to replenish calcium in the blood and also has uses in cardiac resuscitation.
Neuropeptides are small protein-like molecules (peptides) used by neurons to communicate with each other. They are neuronal signaling molecules that influence the activity of the brain in specific ways.
Their signal peptides, however, are completely different in sequence and function: the CRF 2(a) R contains the above-mentioned pseudo signal peptide, whereas the CRF 2(b) R possesses a conventional and cleaved signal peptide (Fig. 7). In principle, signal peptides thus represent good novel drug targets.
