3-(3-hydroxyphenyl)propionic acid

3-(3-Hydroxyphenyl)propionic Acid (m-Hydroxyphenylpropionic acid) is one of the major metabolites of ingested caffeic acid.it inhibited osteoclastogenesis and bone osteoclastic resorptive activity.

Desaminotyrosine (3-(4-Hydroxyphenyl)propionic acid) is a microbially associated metabolite. Desaminotyrosine protects from influenza through augmentation of type I interferon signaling.

Melilotic acid (3-(2-Hydroxyphenyl)propionic acid), also known as melilotic acid or melilotate. Within the cell, 3-(2-hydroxyphenyl)propanoic acid is primarily located in the cytoplasm. Melilotic acid can be biosynthesized from propionic acid. Outside of the human body, 3-(2-hydroxyphenyl)propanoic acid can be found in a number of food items such as herbs and spices, red beetroot, chinese cinnamon, and bilberry. This makes 3-(2-hydroxyphenyl)propanoic acid a potential biomarker for the consumption of these food products.
