Abstract: A process of controlling the production of enzymatic protein hydrolysate from cold water animals, containing up to 90% free amino acids, cold fish oil, hydroxilaptite (calcium orthophosphate), proteins, peptides, vitamin, minerals and calcium salts of phosphorus. The process provides a greater degree of refining than existing technology through the use of acid and alkaline denaturation steps, in combination with advanced separation and drying technology. The new drying technology results in a higher-quality, less expensive mixture than was previously possible.

Abstract: The invention relates to a method of altering hypothalamic function in an individual. The method comprises nasally administering a human vomeropherin, e.g. a 19-nor cholane steroid, or a pharmaceutical composition containing a vomeropherin, such that the vomeropherin binds to a specific neuroepithelial receptor. The steroid or steroids is/are preferably administered in the form of a pharmaceutical composition containing one or more pharmaceutically acceptable carriers. Other embodiments of the invention include pharmaceutical compositions containing the steroids.
