L-肌肽一种二肽，以毫摩尔浓度存在于脑、肌肉和眼睛晶状体中。 在模型系统中，它是一种有效的抗氧化剂，可清除氧自由基和过渡金属离子。 它可以阻断由次氯酸根阴离子以及乙醛、甲醛和丙二醛（脂质过氧化的主要产物）等有毒醛类诱导的蛋白质-蛋白质和蛋白质-DNA交联。 它还能抑制醛糖和酮糖还原糖诱导的非酶促蛋白糖化，并抑制毒性晚期糖基化终产物（AGE）的形成。这些活性使其被用于对衰老、动脉粥样硬化、阿尔茨海默病和糖尿病的继发性影响的研究。
具有强抗氧化性和抗糖化活性的二肽；阻断由反应性醛诱导的非酶促糖基化和蛋白质交联。

Muscle carnosine and its methylated form anserine are histidine-containing dipeptides. Both dipeptides have the ability to quench reactive carbonyl species and previous studies have shown that endogenous tissue levels are decreased in chronic diseases, such as diabetes. Rodent study: Skeletal

Carnosine (β-alanyl-l-histidine) was discovered in 1900 as an abundant non-protein nitrogen-containing compound of meat. The dipeptide is not only found in skeletal muscle, but also in other excitable tissues. Most animals, except humans, also possess a methylated variant of carnosine

Targeting glutamatergic dysfunction provides an exciting opportunity to improve cognitive impairment in schizophrenia. One treatment approach has targeted inadequate antioxidant defenses at glutamatergic synapses. Animal and human data suggest NMDA antagonists worsen executive cognitive controls--e.g. increase perseverative responses and impair

Aggregation of the amyloid-β peptide (Aβ) into fibrillar structures is a hallmark of Alzheimer's disease. Thus, preventing self-assembly of the Aβ peptide is an attractive therapeutic strategy. Here, we used experimental techniques and atomistic simulations to investigate the influence of

It has been hypothesized that exercise-induced changes in metabolites and ions are crucial in the adaptation of contracting muscle. We tested this hypothesis by comparing adaptations to two different interval-training protocols (differing only in the rest duration between intervals), which
