LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism

Denominator Metabolite Explanation:

Glycerophospholipid metabolism

Ratio Explanation:

The ratio reflects the conversion of oleoyl-GPE to arachidonoyl-GPE, a process influenced by FADS desaturase activity, which is a key step in fatty acid metabolism.1[1], 2[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Reduced FADS1/FADS2 activity, indicated by the ratio, is associated with altered blood lipid profiles, including cholesterol levels.3[1] This genetic influence on fatty acid metabolism is linked to a predisposition for pure hypercholesterolaemia.

Phenotype Driver:

Gene-centric:FADS1/FADS2
