LLM Analysis

Numerator Metabolite Explanation:

Omega-3 fatty acid biosynthesis.5[1], 6[2], 7[3], 8[4]

Denominator Metabolite Explanation:

Glycerophosphoinositol metabolism / Phospholipid metabolism.9[1], 10[2]

Ratio Explanation:

The ratio reflects FADS enzyme activity, where higher activity increases docosapentaenoate (DPA) levels, a polyunsaturated fatty acid, relative to glycerophosphoinositol lipid species.11[1], 12[2], 13[3]

Ratio Evidence:

metabolites not in a pathway but enzyme catalyzes one metabolite

Gene Ratio Phenotype Relationship:

FADS gene variants alter desaturase activity, impacting the balance of pro-inflammatory and anti-inflammatory polyunsaturated fatty acids.14[1], 15[2], 16[3] This dysregulation of lipid mediators is associated with inflammatory conditions like asthma and IBD, and metabolic disorders including type 2 diabetes and hypercholesterolemia.14[4], 3[5], 17[6], 18[7]

Phenotype Driver:

Gene-centric:FADS1/FADS2
