求翻译：Fish oil is a source of the omega-3 essential fatty acids. Essential fatty acids are incorporated into every cell membrane in the body, in the form of compounds called phospholipids. Cell membranes play the vital role of regulating what goes into, and what comes out of each cell. The integrity and fluidity of the cell membrane is determined by the type of phospholipid that is available for the body to use. Cell membranes made up mainly of phospholipids derived from the essential polyunsaturated fatty acids are more fluid and function better than cell membranes made up of saturated fat or trans fatty acids. A cell membrane working at optimal levels retains vital nutrients and electrolytes, has the ability to communicate with other cells and is responsive to hormones.是什么意思？
