Abstract
Contents of β-alanine, anserine, carnosine, RNA and DNA were compared in liver and gastrocne mius muscle of β-aianine-treated rats and control for eight weeks after weaning. Effect of β-alanine administration was found greatest in the first week when the metabolism was supposed to change greatly. It is concluded that the increase of RNA contents during growth is repressed, but no effect on DNA. Also accumulation of β-alanine and effect on formation on anserine and carnosine are the most prominent at this point.
