Nervous tissue biological significance

The fats also have a plastic function as they are included in cell membranes and other cell structures. The central and peripheral nervous systems are rich in lipids. PNFA are included in cell membranes, with their most significant function being the synthesis of cell hormones — prostaglandins. The properties of cell membranes as well as their interaction with external factors depend on the relation of PNFA concentration in cell components. In humans, prostaglandins are created not only in tissues but also in thrombocytes (thromboxanes) and in leucocytes (leukotrienes). The biological action of thrombocytes is extremely variant and depends on PNFA type which are the basis for fatty acid creation. 

Amidohydrolase activity is concentrated in liver and brain tissues and, within the brain, in regions rich in cannabinoid receptors (e.g., globus pallidus and hippocampus) (Fig. 6.13). The parallel distribution of receptors and degradative enzyme in the central nervous system is particularly significant, as it supports a participation of anandamide amidohydrolase in the biological disposition of anandamide at its sites of action.
