Phosphatidylserine chemical structure

It appears evident therefore that the main function of most nutrient elements is as a constituent of the enzymes required to build up the organic matter within plants. Many such reactions run side by side in cells and tissues, and this is made possible by the presence of biomembranes that allow the build-up and decomposition of compounds, without mixing the components. Biomembranes subdivide cells into reaction spaces (e.g., nucleus, plastids, mitochondria, ribosomes, vacuoles, cytosol), and they permit well-ordered substance exchange between the compartments. Such processes are also responsible for ion uptake by root cells from the soil solution. Despite certain differences, all biomembranes have a similar chemical structure, the basic components being double lamellae of P-containing lipids (Figure 2.2) such as phosphatidylserine and glycolipids (Table 2.4). Proteins are movably incorporated into these double lamellae (see... 

Glycerol containing phospholipids are used for the preparation of liposomes and vesicles phosphatidylcholine - phosphatidylserine - phosphatidylethanolamine -phosphatidylanisitol - phosphatidylglycerol - phosphatidic acid - cholesterol. The chemical structure of some of these lipids was given before. In most preparations, a mixture of lipids is used to obtain the most optimum structure.
