Microalgal biomass and its cellular components are used as substrates for the production of fuels. A valuable group among microalgal is lipids, which act a precursor biodiesel in transesterification process. Some methods, including creation stressful conditions, applied to increase accumulation lipids. This study aimed determine effect limited nutrient access on growth development microalga Chl...

Phosphatidic acid (PA) and lysophosphatidic acid (LPA) are lipids that regulate cellular processes. PA stimulates kinases and may play a role in exocytosis and membrane fusion. LPA can induce cell proliferation, platelet aggregation, and microfilament formation. Due to the growing interest in these lipids, rapid purification and quantification of these lipids is desirable. We now describe a met...

The effect of epinephrine on triacylglycerol secretion was investigated in isolated rat hepatocytes. The effect appeared at concentrations of more than 1 µM and reached a plateau at 10 µM. Epinephrine concentration for half of the maximal bioeffect (EC50) was about 1 µM. Epineplrrine at a concentration of 10 µM suppressed triacylglycerol secretion by 33% and increased its cellular content b...
