Lac-Phe
Lactoylphenylalanine, or Lac-Phe, is a metabolite generated by intense exercise. In mice, high levels of Lac-Phe in the blood cause a decrease of food intake. In mammals it is created from (S)-lactate and L-phenylalanine by the cytosol nonspecific dipeptidase (CNDP2) protein. It is classified as N-acyl-alpha-amino acid and pseudodipeptide. It has also been reported that as an additive N-L-lactoyl phenylalanine improves the taste of food, conferring an umami flavor. It is found naturally in significant amounts in some traditional Chinese fermented foods such as preserved pickles and soy sauce. Oral intake of Lac-Phe does not have anti-obesity effects in mice.
