    Opis:
    Since energy storage is a basic metabolic process, the synthesis of neutral lipids occurs in all kingdoms of life. The yeast, Saccharomyces cerevisiae, widely accepted as a model eukaryotic cell, contains two classes of neutral lipids, namely steryl esters and triacylglycerols. Triacylglycerols are synthesized through two pathways governed by the acyl-CoA diacylglycerol acyltransferase Dga1p and the phospholipid diacylglycerol acyltransferase Lro1p, respectively. Steryl esters are formed by the two steryl ester synthases Are1p and Are2p, two enzymes with overlapping function which also catalyze triacylglycerol formation, although to a minor extent. Storage of neutral lipids is tightly linked to the biogenesis of so called lipid particles. The role of this compartment in lipid homeostasis and its interplay with other organelles involved in neutral lipid dynamics, especially the endoplasmic reticulum and the plasma membrane, are subject of current investigations. In contrast to neutral lipid formation, mobilization of triacylglycerols and steryl esters in yeast are less characterized at the molecular level. Only recently, the triacylglycerol lipase Tgl3p was identified as the first yeast enzyme of this kind by function. Genes and gene products governing steryl ester mobilization still await identification. Besides biochemical properties of enzymes involved in yeast neutral lipid synthesis and degradation, regulatory aspects of these pathways and cell biological consequences of neutral lipid depletion will be discussed in this minireview.

    Opis:
    The results of the research on estimation the molar heat of formation (enthalpy) of model triglycerides found in natural oils and fats are presented. In this work a calculation method and calorimetric one were used. It was found that combustion heat values determined by separate methods are comparable; their difference was a maximum of 155 kJ/kg, and thus was significantly lower than the tolerance for the calorimetric method according to PN 86/C-04062.

    Opis:
    Atherosclerosis is an inflammatory disease characterised by the accumulation of lipids and their metabolites in the artery wall. During inflammation circulating LDL are taken up by macrophages through two major scavenger receptors: CD36 and scavenger receptor A (SRA). Fatty acids that are common in food, e.g. linoleic acid and n-3 unsaturated fatty acids can modulate expression of CD36 on the macrophage surface. Conjugated linoleic acid isomers (CLA) that originate from the human diet, have demonstrated antiatherogenic properties in several experiments. Animal study evidenced that CLA could induce resolution of plaque by activation of peroxisome proliferator activated receptors and down-regulation of pro-inflammatory genes. Less unequivocal results were obtained in human studies (on the CLA effects on the inflammatory process). Therefore in this study we investigated the influence of CLA on CD36 expression and lipid accumulation in human macrophages. Macrophages were incubated with 30 µM cis-9,trans-11 CLA, trans-10,cis-12 CLA or linoleic acid for 48 h. After that, expression of CD36 as well as accumulation of lipids were measured by flow cytometry, microscopy and a spectroscopic method. We demonstrate that both cis-9,trans-11 C 18:2 CLA and linoleic acid slightly elevated expression of CD36, whereas second isomer - trans-10,cis-12 CLA - did not. Nevertheless, only trans-10,cis-12 CLA triggered delipidation of macrophages, that is decreased triacylglycerols concentration. Also in human adipocytes, trans-10,cis-12 CLA causes cell delipidation by reduction of PPAR receptor expression. We propose a similar mechanism for human macrophages/foam cells.
