Specific distribution of fatty acids in the triglycerides of rainbow trout adipose tissue. Influence of temperature

In the trout, the unsaturated fatty acids are preferentially located in the β‐position and the saturated fatty acids in the α‐position of triglycerides. This fatty acid distribution is retained even with diets containing lard. The fish are, therefore, able to modify completely the fatty acid distrib...

Summary:In the trout, the unsaturated fatty acids are preferentially located in the β‐position and the saturated fatty acids in the α‐position of triglycerides. This fatty acid distribution is retained even with diets containing lard. The fish are, therefore, able to modify completely the fatty acid distribution of dietary triglycerides. There is no retention of the β‐monoglyceride structure during the biosynthetic processes. However, the modification of the dietary fatty acid distribution by the trout seems to be more difficult at 18 C than at 10C.
