LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism

Denominator Metabolite Explanation:

Glycerophospholipid metabolism

Ratio Explanation:

The ratio reflects the relative activity of fatty acid desaturase enzymes (FADS1/FADS2) in the synthesis of different polyunsaturated fatty acid-containing phospholipids.

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variants in the FADS gene cluster influence the activity of FADS1 and FADS2 enzymes, altering the balance of specific long-chain polyunsaturated fatty acids.4[1], 5[2], 6[3] This altered lipid profile is associated with variations in cholesterol and lipoprotein levels, contributing to risks for hypercholesterolemia and related metabolic disorders.7[4], 8[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
