The effect of ethanol consumption on folate polyglutamate biosynthesis in the rat

Contrary to previous studies, the folate polyglutamate chain length in the rat liver appears to be unaffected by ethanol ingestion for periods of 2-13 weeks. The appearance of short chain length folates after 13 weeks has been shown to arise as a result of increased in vitro folate polyglutamate breakdown during extraction due to a greater release of lysosomal conjugase in these animals.
