the similarity in hplc retention times and molecular weights of this fura derivative and the bile acids n-cholylglycine ( mr 465 ) and n-cholyltaurine ( mr 515 ) , along with the structural similarity of the fura catabolite 2-fluoro-beta-alanine and the amino acids glycine and taurine , led to the hypothesis that this metabolite could be a conjugate of 2-fluoro-beta-alanine and cholic acid .
