<p>The aim of this study was to investigate the efficiency of different extraction methods for total lipid determination and oxidative rancidity evaluation in freshwater fish with different fat levels. Total lipid content was determined by Bligh and Dyer with slight modifications and Soxhlet methods. Malondialdehyde (MDA) quantification was determined by analytical methods with and without heat application. In both freshwater fish species, Bligh and Dyer method extracted greater total lipid content (<em>P</em> &lt;0.05) than Soxhlet method. In addition, the heat method revealed higher MDA values (<em>P</em> &lt;0.05) compared to cold method in both lean fish (<em>Cichla ocellaris</em>) and high-fat fish species (<em>Piaractus brachypomus</em>). We concluded that, regardless of the fat content in the freshwater fish species, the Bligh and Dyer method and the cold method used for oxidative rancidity were more efficient than Soxhlet method and heat technique, respectively.</p>

The Relationship

Seasonal changes in the percent total lipid content of Mysis relicta were investigated in four lakes in southern Ontario. Stony and Twelve Mile lakes contain populations of Mysis with a 1-yr life cycle, while Crystal and Boshkung lakes have populations with a 2-yr life cycle. Mature female and male mysids have a lipid content between 15 and 33% and between 14 and 25%, respectively, while juvenile mysids have approximately 10% less total lipids than adults. The relationship between total lipid and lipid-free dry weight is best described by the power curve Y = aXb and is the same (ANCOVA, p < 0.05) in all four mysid populations. Lipid content accumulates steadily with time as the mysid grows, and lipid reserves do not appear to influence mysid time to maturity. For studies on the transfer of energy and lipophilic organic contaminants through the food web, the results imply that seasonal and body size differences of organisms are important considerations.

The Relationship

Methods of estimating total lipid content in the redhead duck (Aythya americana) without performing time-consuming ether extractions are presented. The relationship between various condition indices and total lipid content was investigated. Weights of the whole skin and the abdominal fat depot were easily obtained, good predictors of total body lipids. Total length was the best predictor of fat-free carcass weight.

Objective: Lipids are secreted into milk as bilayer-coated structures: milk lipid globules (MLGs). Adipophilin (ADRP) and perilipin 3 (TIP47) are associated with MLGs in human breast milk; however, the role of these proteins in milk lipid secretion is not fully understood. The aim of the study was to investigate levels of ADRP, TIP47 and total lipid content in human breast milk, their mutual correlations and dynamics during lactation. Research Methods &amp; Procedures: Milk samples from 22 healthy lactating women (Caucasian, Central European) were collected at five time points during lactation (1&ndash;3, 12&ndash;14, 29&ndash;30, 88&ndash;90 and 178&ndash;180 days postpartum). Mass spectrometry-based method was used for quantification of ADRP and TIP47 in the samples. The gravimetric method was used to determine milk total lipid content. Results: We observed distinctive trends in ADRP, TIP47 levels and lipid content in human breast milk during the first 6 months of lactation. We also found a significant association between lipid content and ADRP, lipid content and TIP47, and ADRP and TIP47 concentrations in breast milk at all sampling points. Moreover, we derived an equation for estimating the mean lipid content of milk based on ADRP concentration in human breast milk. Conclusions: A mass spectrometry-based method was developed for quantifying ADRP and TIP47 in human breast milk. Strong mutual correlations were found between ADRP, TIP47 and total lipid content in human breast milk.
