脂类作为细胞功能的强大而多样的调节剂,作为膜结构的决定因素,作为细胞表面受体的配体,作为膜相关蛋白的锚,以及作为“第二信使”,已经浮出水面。其中一些功能直接涉及复杂的脂质,神经节苷脂改变受体的行为就是例证。然而,许多其他功能需要裂解膜脂来产生(例如):不饱和脂肪酸,它被转化为前列腺素、前列环素、血栓烷和其他化合物;二酰甘油,它激活蛋白激酶C;肌醇磷酸,它刺激细胞内储存的钙的释放;以及溶烷基磷脂酰胆碱,它被转化为血小板激活因子。膜脂的新作用正在不断出现,例如鞘氨醇抑制蛋白激酶C和激素反应释放磷脂酰肌醇连接的蛋白。这些脂质系统的饮食改变可能对正常细胞功能和疾病有重要影响。
Lipids have surfaced as potent and diverse modulators of cell functions, as determinants of membrane structure, as ligands for cell-surface receptors, as anchors for membrane-associated proteins, and as "second messengers." Some of these functions involve the complex lipids directly, as exemplified by the alteration of receptor behavior by gangliosides. However, many other functions entail cleavage of membrane lipids to yield (as examples): unsaturated fatty acids, which are converted to prostaglandins, prostacyclins, thromboxanes, and other compounds; diacylglycerols, which activate protein kinase C; inositol phosphates, which stimulate release of calcium from intracellular stores; and lysoalkylphosphatidylcholine, which is converted to platelet-activating factor. New roles for membrane lipids are constantly appearing, such as the inhibition of protein kinase C by sphingosine and the release of phosphatidylinositol-linked proteins in response to hormones. Dietary modification of these lipid systems could have important implications for normal cell function and disease.
