Resumen:
Lipids are important constituents of cell membranes and play a major role in metabolicprocesses. They are composed of fatty acids (FA) of different chain lengths that may besaturated or unsaturated. The FA profile in the adipose tissue is modified through diet.The aim of this study was to compare the FA profile of four tissues (muscle, serum,fatty body and adipose tissue) of Caiman latirostris bred for two years by ProyectoYacaré. The FA profile was determinate by gas chromatograph. Data were analyzed bysimilarity analysis (ANOSIM), non metrical multidimensional scaling (NMDS) andprincipal component analysis (PCA). The results show that FA profile of adipose tissueand fatty body were similar (regarding to polyunsaturated and saturated FA), and theywere different from the serum and muscle. The muscle is characterized by the presenceof linolenic, eicosapentaenoic and docosahexaenoic acids (fatty acids that are of greatimportance for health and are recommended for human consumption), while the adiposetissue and the fatty body have FA such as linolenic, eicosatrienoic and docosatrienoicand saturated fatty acid like myristic. The serum was characterized by polyunsaturatedfatty acids such as arachidonic, docosadienoic, linoleic, and saturated fatty acids likestearic. In the muscle we find different polyunsaturated fatty acids in comparison withthe fatty body and adipose tissue. This would be related to the different functions of thetissues. The knowledge of the fatty acids composition of these tissues could definepossible uses of them and allow modifying the diet to improve FA profiles.
