摘要

Serum triglyceride levels are associated with metabolic disorders; however, it remains unclear whether the fatty acid (FA) composition of triglycerides is also changed. Although there were no differences in circulating triglyceride levels between normoglycaemic-normoinsulinaemic and hyperglycaemic-hyperinsulinaemic men, inspection of individual FA revealed that vaccenic acid was enriched with hyperglycaemia-hyperinsulinaemia. Moreover, vaccenic acid levels were positively correlated with insulin and HOMA-IR. This reinforces that examination of individual FA in the context of insulin resistance is warranted.
