PC1 vs PC2 of each pathway class protein counts. Red squares represent facial skin samples, blue triangles represent gut samples. The examined pathway classes were: 1—Amino acid metabolism. 2—Metabolism of other secondary metabolites. 3—Carbohydrate metabolism. 4—Energy metabolism. 5—Glycan biosynthesis and metabolism. 6—Lipid metabolism. 7—Metabolism of co-factors and vitamins. 8—Metabolism of other amino acids. 9—Metabolism of terpenoids and polyketides. 10—Biodegradation and metabolism of xenobiotics
