LLM Analysis

Numerator Metabolite Explanation:

Linoleic acid metabolism3[1]

Denominator Metabolite Explanation:

Fatty acid biosynthesis4[1], 5[2]

Ratio Explanation:

The ratio of dihomo-linoleate to myristoleate may reflect the balance between elongation of polyunsaturated fatty acids and de novo lipogenesis, influenced by SCD activity.

Ratio Evidence:

metabolites not in a pathway but enzyme catalyzes one metabolite

Gene Ratio Phenotype Relationship:

SCD gene variants can alter the balance of fatty acids, potentially influencing membrane fluidity and signaling pathways implicated in cardiovascular diseases like myocardial infarction and hypertension.6[1], 7[2]

Phenotype Driver:

Gene-centric:SCD
