Select fatty acids used as substrate and product of D9D, desaturase index and major CLA isomers are reported. The * 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. Caucasian Males: n = 113; Caucasian females: n = 298; Asian Males: n = 98; Asian Females: n = 277.
