1889 Nature 26 Sept. 525/1 The words in question, ‘anabolism’, which being interpreted means winding up, and ‘catabolism’, running down, are the creation of Dr. Gaskell. Prof. Hering's equivalents for these are ‘assimilation’, which, of course, means storage of oxygen and oxidizable material, and ‘disassimilation’, discharge of these in the altered form of carbon dioxide and water.
