植物甾醇在水产动物中的研究进展.

Phytosterols are a class of natural alcohol compounds with cyclopentane-perhydrophenanthrene as the skeleton. Its structure is similar to cholesterol/sterol, and it usually exists on plant cell membranes in the form of free state, esterified state and glycoside. Because of its cholesterol-lowering, anti-oxidation, prevention of cardiovascular disease and other physiological functions, it has been widely concerned in medicine and, livestock and poultry animals research in recent years. phytosterols have been widely used in the feed and medicine of livestock and poultry animals, and have shown good application effects in promoting growth, improving physiological metabolism, and regulating immunity. There are obvious differences in physiological metabolism between aquatic animals and livestock and poultry animals. At present, the research reports of phytosterols in aquatic animals are very scarce. In this review, the structure and function of phytosterols, the level of phytosterols in some feed raw materials and the detection methods of phytosterols were reviewed, and the application of phytosterols in aquatic animal feeds such as fish and aquatic crustaceans were summarized. Under the current policy background of green and healthy aquaculture proposed by the state, the development of phytosterols into green and safe aquatic feed additives has far-reaching significance for the healthy development of aquaculture. It is of far-reaching significance to develop phytosterols into green and safe aquatic feed additive products to realize the green development of aquaculture industry. [ABSTRACT FROM AUTHOR]
