LLM Analysis

Numerator Metabolite Explanation:

Phosphatidylethanolamine biosynthesis.4[1], 5[2]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism.6[1], 7[2]

Ratio Explanation:

The ratio reflects the conversion of lysophosphatidylethanolamine to phosphatidylethanolamine by the acylation of linoleic acid, a process influenced by FADS activity on fatty acid availability.

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

FADS gene variants influence the abundance of polyunsaturated fatty acids, which alters the composition of phospholipids like those in the ratio, impacting lipid profiles and contributing to hypercholesterolemia risk.8[1], 9[2]

Phenotype Driver:

Gene-centric:FADS1/FADS2
