LLM Analysis

Numerator Metabolite Explanation:

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

Denominator Metabolite Explanation:

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

Ratio Explanation:

The ratio of palmitoleoylcarnitine (C16:1) to stearoylcarnitine (C18) serves as a surrogate marker for SCD activity, reflecting endogenous monounsaturated fatty acid synthesis.10[1], 11[2]

Ratio Evidence:

canonical reaction catalyzed by the enzyme

Gene Ratio Phenotype Relationship:

Altered SCD activity, indicated by the C16:1/C18 acylcarnitine ratio, is linked to dyslipidemia and an elevated risk for cardiometabolic diseases such as atherosclerosis, hypertension, and myocardial infarction.10[1], 12[2]

Phenotype Driver:

Gene-centric:SCD
