Select fatty acids used as substrate and product of D9D, desaturase index and major CLA isomers are reported. *denotes p-values which are significant (< 0.05). P-values were determined using linear regression models which were adjusted for BMI, age, % of Total Energy from Dietary Fat and physical activity. Abbreviations: HC, females using hormonal contraceptives; non, females that are not using hormonal contraceptives.
