APPENDIX 



THE STRUCTURAL FORMULAS AND PRIN- 

 CIPAL ACTIONS OF HORMONES OF 

 NATURAL ORIGIN 



Notable advances have been made in isolating and de- 

 termining the structure of hormones and of substances 

 necessary for their synthesis or produced in their degrada- 

 tion. Moreover, a number of synthetic hormones has been 

 made. The skill of chemists has been most fruitfully applied 

 in studying substances with a nucleus derived from cyclo- 

 pentenophenanthrene. 



The table and formulas of the x-^ppendix deal only with 

 hormones or related substances of natural origin and of 

 known structure. Although the list is believed to be complete 

 at this time, it undoubtedly will be lengthened as a result of 

 future research. The substances are listed alphabetically in 

 the table which includes data believed to be of greatest 

 interest to readers of this book. The formulas likewise are 

 arranged alphabetically and follow the table.
