概括

肠道微生物将草化合物转化为代谢物,影响血管健康. 草消费和健康的肠道微生物组可以减轻高脂肪饮食引起的血管炎症.

科学领域:

微生物组和新陈代谢
营养生物化学营养生物化学
血管生物学血管生物学

背景情况:

肠道微生物在代谢饮食中的植物化学物质中的作用至关重要,但尚未完全理解.
肠道功能失调可能会影响植物化学代谢物生产和生物活动.
有限的研究存在于肠道微生物,代谢物和植物化学效应之间的相互作用.

研究的目的:

研究肠道微生物对草植物化学物质生物活动的影响.
探索肠道失调如何影响植物化学代谢和相关的健康益处.
为了确定来自草的特定微生物代谢物及其对血管健康的影响.

主要方法:

给小鼠提供含有或不含草的饮食,一些小鼠接受了抗生素来改变肠道微生物群.
饮食包括标准,草补充,高脂肪 (HFD) 和草补充的HFD.
分析了代谢物生产,肠道微生物组成和血管炎症.

主要成果:

抗生素治疗减少了草代谢物产量 (例如,p-coumaric酸) 并取消了草对血管的益处.
由HFD诱导的失生症损害了代谢物生产;希普酸被确定为与HFD相关的微生物代谢物.
草减少了HFD诱导的血管炎症,这种炎症由肠道微生物和特定代谢物,如hippuric acid进行介导.

结论:

肠道微生物对于生产草衍生代谢物至关重要,这些代谢物会给血管带来好处.
由HFD引起的肠道失调会对代谢物产生产生负面影响,并降低草对健康的益处.
草可以作为一种营养策略,通过调节肠道微生物群及其代谢物来预防血管并发症.

Overview of Metabolism

Overview of Metabolism

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.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Bacterial Flora of the Large Intestine

Bacterial Flora of the Large Intestine

The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

What is Monogastric Digestion?

What is Monogastric Digestion?

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.
