LLM Analysis

Numerator Metabolite Explanation:

Fatty acid biosynthesis, beta-oxidation.

Denominator Metabolite Explanation:

Fatty acid biosynthesis, beta-oxidation.

Ratio Explanation:

The ratio of palmitoleoylcarnitine (downstream product) to myristoylcarnitine (upstream precursor) serves as a functional indicator of Stearoyl-CoA Desaturase (SCD) enzyme activity.3[1]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variation in SCD alters its catalytic activity, reflected by the C16:1/C14 carnitine ratio.3[1] This dysregulation of lipid metabolism is strongly associated with cardiometabolic phenotypes, including coronary atherosclerosis and hypercholesterolemia.3[2], 1[3], 4[4]

Phenotype Driver:

Gene-centric:SCD
