In many respects, the steroids also seem to fall within this class. This enormous generalization induced from structure determination studies led to the hypothesis that all of these molecules are made in the cell by a single route â that they are products of a common biogenetic pathway. In recent years, great progress has been made in mapping this pathway.

Was James Cook really a Captain? When Cook set sail in 1768 on his first voyage of discovery aboard Endeavour he held the rank of lieutenant. Soon after his return to England in 1771 he was promoted to the rank of commander. He never actually held the rank of captain, but in 1775 was promoted to the higher rank of post-captain. Any person in charge of a ship is known as its captain, and so it was quite natural to refer to him as Captain Cook.
