- * 营养生物化学和脂质组学.
- * 人口健康和流行病学.
背景情况:
- *代谢相关的脂肪性肝病 (MASLD) 涉及肝脏三糖醇 (TAG) 积累,与其他脂质有关.
- * 胆代谢,特别是酸丁胆 (PC),与通过非常低密度脂蛋白 (VLDL) 的肝脏TAG去除有关.
- * 综合脂管学,胆代谢物和MASLD的基于人群的研究很少.
研究的目的:
- * 在基于人口的队列中调查血脂组,胆代谢物和MASLD之间的关联.
- * 为了探索脂肪酸成分在酸丁胆 (PC) 和三糖醇 (TAG) 中的作用,与MASLD有关.
- * 检查胆代谢物 (如贝他因) 和MASLD之间的关系,以及它们与血脂组的联系.
主要方法:
- *利用了来自1039名冠状动脉风险发展在年轻成年人 (心脏) 研究的参与者的数据.
- * 用液体染色学和输液质谱学量化血脂组和胆代谢物.
- *使用CT衍生的肝衰减 (<51 HU) 定义了MASLD,并使用后勤回归进行分析.
主要成果:
- * 发现了MASLD和总TAG,二糖醇 (DAG) 和二糖胺 (DCER) 之间的积极关联;与乳糖糖胺 (LCER) 的反向关联.
- * 酸胆 (PC) 与MASLD的相关性因脂肪酸 (FA) 组成而有所不同.
- *贝他因与MASLD相反相关;脂质学风险评分 (LRS) 与胆相对正相关,与贝他因相反相关.
结论:
- *以人口为基础的数据证实了特定脂质特征,胆代谢物和MASLD之间的联系.
- * 脂质的脂肪酸组成,特别是PC和TAG,与MASLD有关.
- * 胆代谢物与血脂组和事件MASLD相连,支持生物标志物发育和机理性见解.

Lipid-derived Compounds in the Human Body
5.5K
Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

Overview of Lipid Metabolism
7.0K
Lipid metabolism is a crucial process in the human body that involves the synthesis and degradation of lipids. This process is essential for energy production, cell membrane formation, and hormone production, among other functions.
Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

Cholesterol: Significance and Regulation
2.1K
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.

Atherosclerosis I: Introduction
2.5K
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Lipid Catabolism
1.4K
Triglycerides serve as crucial long-term energy storage molecules in microorganisms, providing a dense source of metabolic energy. Their breakdown is mediated by lipases, which hydrolyze triglycerides into glycerol and free fatty acids. Each of these components follows distinct metabolic pathways, ultimately contributing to ATP synthesis and cellular energy homeostasis.Glycerol MetabolismGlycerol, released from triglyceride hydrolysis, is phosphorylated by glycerol kinase to form...
