脂类物质在虾类营养与代谢中起重要作用。脂肪乃是良好的能源,每克脂肪氧化可释放9千卡热量,是等量的糖或蛋白质所含潜热(4千卡/克)的一倍以上;类脂(磷脂、糖脂、固醇脂)是生物膜的主要构成成分,它们在脂类物质消化吸收与转运方面也起着重要的作用;固醇脂可用来合成维生素D、脑激素及脱皮激素等。脂肪还有助于一些脂溶性维生素(如维生素A、D、E、K)的消化和吸收。必需脂肪酸是虾类成活与生长必不可少的物质。饵料中 Lipids play an important role in the nutrition and metabolism of shrimp. Fat is a good source of energy and can release up to 9 kilocalories per gram of fat oxidation, more than double the latent heat (4 kcal / g) contained in the same amount of sugar or protein; lipids (phospholipids, glycolipids, sterols Lipids) are the main components of biofilms, which also play an important role in the digestion and absorption of lipids and transport; sterol fat can be used to synthesize vitamin D, brain hormones and epidermal hormone. Fat also helps digestion and absorption of some fat-soluble vitamins (such as vitamins A, D, E, K). Essential fatty acids are essential for the survival and growth of shrimp. In bait
