The lecithins and cephalins are complex mixtures of chemical entities differing from each other (a) in their component fatty acids, (h) in the case of the cephalins, in the nitrogenous constituent, and (c) in the point of substitution of t.he phosphoric acid-base group in the molecule. Power and Tutin (I) were the first to question the uniformity of the glycerophosphoric acids of lecithin. In 1...

In 1944, Taurog et al. (1) pointed out that practically all of the phospholipides in plasma of man and dog contain choline. This indicates that the plasma phospholipides of these two species consist almost entirely of lecithins and sphingomyelins. Confirmation of this finding has now come from Hack (2) and from Sinclair (3-5). The former reported that about 95 per cent of the phospholipides in ...

Grapevine, a crop of global economic importance, is annually affected by diseases that can compromise the quality and quantity harvest, producing large losses. Downy mildew caused Plasmopara viticola (Berk. & M.A. Curtis) Berl. de Toni one most important in vineyard. To fight this pathogen, winegrowers often rely on conventional chemical fungicides or copper-based formulations, whose use de...

In order to evaluate to the feasibility of using lecithins for nanocapsules including functional food materials, liposomes were prepared from different commercially available lecithins (SLP-WHITE, SLP-PC70 and PL30S) by the Bangham method, and their physicochemical properties were examined by using a confocal laser scanning microscopy (CLSM) and the measurements of trapping efficiency. There wa...
