LLM Analysis

Numerator Metabolite Explanation:

Fatty acid metabolism, Beta-oxidation.4[1], 5[2], 6[3]

Denominator Metabolite Explanation:

Fatty acid biosynthesis.7[1], 8[2], 9[3]

Ratio Explanation:

The ratio of palmitoleoylcarnitine to stearate reflects the activity of Stearoyl-CoA Desaturase (SCD), which converts stearate into monounsaturated fats, influencing lipid composition and metabolism.1[1], 3[2], 10[3]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Higher SCD activity, indicated by a higher ratio, is associated with increased synthesis of monounsaturated fatty acids which can lead to hypertriglyceridemia, atherosclerosis, and other metabolic disorders.2[1], 11[2], 12[3] This aligns with the observed phenotypes of coronary atherosclerosis and hypercholesterolemia.

Phenotype Driver:

Gene-centric:SCD
