LLM Analysis

Numerator Metabolite Explanation:

Phosphatidylcholine biosynthesis4[1], 5[2]

Denominator Metabolite Explanation:

Phosphatidylcholine biosynthesis6[1], 7[2]

Ratio Explanation:

This ratio reflects the balance between omega-6 (linoleoyl) and omega-3 (docosahexaenoyl) fatty acid incorporation into phosphatidylcholines, influenced by FADS desaturase activity.8[1], 1[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Variants in the FADS gene cluster alter desaturase enzyme activity, impacting the balance of omega-6 and omega-3 PUFAs.1[1], 9[2], 10[3] This dysregulation of lipid metabolism is associated with an increased risk for pure hypercholesterolemia.9[4], 11[5], 12[6]

Phenotype Driver:
