概括

甲基马龙酸 (MMA) 的升高,是线粒体功能障碍的标志物,与较低的骨矿物质密度 (BMD) 有关. 这凸显了新陈代谢健康对于预防骨质疏松症的重要性.

科学领域:

生物化学生物化学
骨的新陈代谢骨的新陈代谢
老年学是指老年学的学科.

背景情况:

甲基马龙酸 (MMA) 是线粒体功能障碍的生物标志物.
骨矿物质密度 (BMD) 对于骨健康和骨质疏松症的评估至关重要.
线粒体功能障碍可能会影响各种生理过程,包括骨健康.

Bone Disorders

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
