LLM Analysis

Numerator Metabolite Explanation:

Fatty acid metabolism, Carnitine shuttle4[1]

Denominator Metabolite Explanation:

Fatty acid biosynthesis5[1]

Ratio Explanation:

The ratio of stearoylcarnitine to palmitoleate is an indicator of SCD enzyme activity, which converts saturated to monounsaturated fatty acids.6[1], 7[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Lower SCD activity, indicated by a higher ratio, alters lipid profiles, which is a risk factor for cardiometabolic diseases like atherosclerosis and myocardial infarction.8[1], 9[2] This aligns with the observed phenotypes of ischaemic heart disease and hypercholesterolaemia.

Phenotype Driver:

Gene-centric:SCD
