Tryptophan Metabolism in Alcoholism [PDF]
Nutrition Research Reviews, 1999 Studies of tryptophan (Trp) metabolism in relation to the serotonin status in alcoholism are of 2 types: (1) those related to the pharmacological effects of ethanol; (2) those concerning the serotonin status in the absence of alcohol intake. In experimental animals, acute and chronic ethanol administration and subsequent withdrawal exert a variety of ...
