β-羟丁酸:代谢健康的神秘钥匙
2024年12月18日 · 本文将从BHB的生成与功能、在疾病中的作用、以及作为外源性补充物的酮肽(BHB-P)的优势和应用等多个方面,深入解析β-羟丁酸的奥秘。 BHB是脂肪酸在肝脏中进行分解代谢时生成的特殊中间产物,是血中酮体的主要成分,约占酮体总量的78%。 在正常人体中,BHB的含量极低,这是人类利用脂肪氧化供能的正常现象。 然而,在某些生理情况(如饥饿、禁食)或病理情况(如糖尿病)下,糖的来源或氧化供能出现障碍,脂动员增强,脂肪酸成为人 …
β-Hydroxybutyric acid - Wikipedia
β-Hydroxybutyric acid, also known as 3-hydroxybutyric acid or BHB, is an organic compound and a beta hydroxy acid with the chemical formula CH 3 CH(OH)CH 2 CO 2 H; its conjugate base is β-hydroxybutyrate, also known as 3-hydroxybutyrate. β-Hydroxybutyric acid is a chiral compound with two enantiomers: D-β-hydroxybutyric acid and L-β ...

Beta-hydroxybutyrate (BHB) is a chemical that is made by the body. It provides energy when not enough carbohydrates or sugars have been eaten. BHB can also be made in the...
A β-hydroxybutyrate shunt pathway generates anti-obesity ketone ...
2025年1月9日 · β-Hydroxybutyrate (BHB) is an abundant ketone body. To date, all known pathways of BHB metabolism involve the interconversion of BHB and primary energy intermediates. Here, we identify a previously undescribed BHB secondary metabolic pathway via CNDP2-dependent enzymatic conjugation of BHB and free amino acids.
β-Hydroxybutyrate: A Signaling Metabolite - PMC - PubMed …
Here, we review the signaling activities of the endogenous metabolite β-hydroxybutyrate (BHB). BHB is the most abundant ketone body in mammals. Ketone bodies are small molecules synthesized primarily in the liver from fats that circulate through the bloodstream during fasting, prolonged exercise, and when carbohydrates are restricted.
3-Hydroxybutyric acid (β-Hydroxybutyric acid,3-羟基丁酸)
3-Hydroxybutyric acid (β-Hydroxybutyric acid) 能够与脂质相互作用 (使用 DPPC 单层建模) 并在临床浓度下改变相行为。 3-Hydroxybutyric acid 还会降低 DPPC 单分子层的界面粘度 [1]。 MCE has not independently confirmed the accuracy of these methods.
