چکیده
In the crystal structure of the title compound, C(11)H(11)FO(2), the methine CH forms an intra-molecular hydrogen bond with the carboxyl- O atom. The mol-ecules form dimers through hydrogen bonding between carboxyl- groups. These dimers are linked to each other by C-H⋯O contacts between the benzene and carbonyl groups of adjoining mol-ecules. In addition, there are weak inter-molecular C-H⋯F contacts.

In the title compound, C(14)H(10)FNO(3), the dihedral angle between the two benzene rings is 32.66 (14)°. An S(6) ring motif is formed due to an intra-molecular O-H⋯O hydrogen bond between the hy-droxy and carbonyl groups. In the crystal, mol-ecules are consolidated into dimers with R(2) (2)(8) ring motifs by pairs of O-H⋯O hydrogen bonds.

متن کاملIntestinal cell conversion of DL-2-hydroxy-(4-methylthio)butanoic acid in vitro: dietary up-regulation by this methionine precursor.
DL-2-Hydroxy-(4-methylthio)butanoic acid (HMTBA) is a synthetic source of dietary methionine (Met) widely used in poultry nutrition. HMTBA is transported in the intestinal epithelium by the monocarboxylate transporter 1, after which its biological utilisation relies on its conversion to L-Met. This process involves stereospecific HMTBA oxidation to 2-keto-(4-methylthio)butanoic acid (KMB) and t...
