概括
咖啡酸乙烯 (CAPE) 补充改善了草利用高碳水化合物饮食 (HCD) 的能力. 在养HCD的鱼类中,CAPE促进生长,减少代谢不良影响,减轻炎症.
科学领域:
- 水产养殖营养
- 鱼类生理学
- 代谢健康
背景情况:
- 高碳水化合物饮食对水产养殖至关重要,但可以引起鱼类的代谢障碍.
- 提取物,特别是咖啡酸乙烯 (CAPE),具有抗炎和肝脏保护性质,这表明对HCD养的鱼类有潜在的益处.
研究的目的:
- 为了研究CAPE对草鱼 (Ctenopharyngodon idellus) 的影响,养了一只HCD.
- 评估CAPE对草生长性能,组织健康和营养代谢的影响.
主要方法:
- 在8周的时间里,草被食了HCD,并补充了不同水平的CAPE (200,500,800毫克/公斤) 或对照饮食.
- 分析了与代谢和炎症相关的生长参数,料转化率,组织指数,血清生物化学和基因表达.
主要成果:
- HCD显著降低了生长性能和蛋白质沉积,同时增加了脂肪积累和肝脏指数.
- 补充CAPE可以改善这些负面影响,改善生长并降低肝体指数.
- 在脂肪组织中激活过氧体增殖器激活受体γ (PPARγ),促进脂肪细胞增生和减少炎症.
- 增强脂解,脂肪酸氧化,葡萄糖吸收和脂质代谢,同时降低血清炎症标志物和代谢障碍.
结论:
- 通过改善葡萄糖和脂质代谢并减少炎症,CAPE有效地减轻了草鱼中HCD的不良代谢作用.
- 补充CAPE是一种有前途的策略,可以提高水产养殖中HCD的利用率,促进鱼类的健康和生长.

Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.

Carbohydrate digestion and metabolism break down simple and complex carbohydrates from food into saccharides (i.e., sugars) for the body to use as energy. Carbohydrate digestion starts in the mouth during mastication, or chewing. The masticated carbohydrates remain intact in the stomach. Digestion resumes in the duodenum of the small intestine, where pancreatic alpha-amylase and brush border enzymes of the microvilli convert complex carbohydrates to monosaccharides. Finally, the monosaccharides...

01:57Adaptations that Reduce Water Loss
26.3K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...
