Therefore, this study aims to understand the salinity-dependent growth and lipid metabolism of white shrimp by analyzing fatty acid composition of different tissues, enzyme activity related to fatty acid catabolism (hormone sensitive lipase [HSL], lipoprotein lipase [LPL], adipose triacylglycerol lipase
[ATGL]) and synthesis (elongase of very long chain fatty acids 6 [ELOVL6], fatty acid synthase [FAS] complex, [DELTA]5 fatty acid desaturase [[DELTA]5FAD], and [DELTA]6 fatty acid desaturase [[DELTA]6FAD]), and the contents of metabolic products of Litopenaeus vannamei at 3 salinities.
The quantities measured and the corresponding analyzers were as follows: serum concentrations of apolipoprotein A1, apolipoproteins B, bilirubin (nonesterified), chloride, cholinesterase, HDL-cholesterol, L-lactate dehydrogenase, lipoprotein(a), pancreatic a-amylase, peptidyl dipeptidase A, transferrin, and triacylglycerol lipase
were measured with the Modular System (Roche Diagnostics); serum magnesium concentrations were measured with the Dimension RxL (Dade Behring); serum concentrations of CA 15-3 antigen, CA 19-9 antigen, CA 125 antigen, a-fetoprotein, [[beta].
We have shown that a lipolytic enzyme normally expressed in the pancreas and released into the gut, pancreatic triacylglycerol lipase
(PTL), is expressed in the heart and the WAT of hibernating 13- lined ground squirrels (Spermophilus tridecemlineatus).
