PC and sarcopenia: Specifically, we observed changes in pathways such as undecaprenyl‐phosphate galactose phosphotransferase, pyruvate carboxylase, pyruvate decarboxylase subunit B, 4‐carboxymuconolactone decarboxylase and aminobenzoic‐glutamate utilization protein A. On the other hand, in cirrhotic patients without sarcopenia, an association with the functional profile related to fatty acid biosynthesis (3‐oxoacyl‐[acyl‐carrier‐protein] synthase) was observed.
