Role of carnosine in muscle contraction

Carnosine is known to be an antioxidant, a metal chelator, a Ca(2+) and enzyme regulator. It also functions as an inhibitor of protein glycosylation and protein-protein cross-linking. Carnosine has also been linked to overcoming muscle fatigue, and can only be transported into a working muscle cell. This pathway shows the main metabolites of carnosine and their relationship with each other.

卡诺辛作为一种抗氧化剂、金属螯合剂、钙离子（Ca(2+)）和酶的调节因子而广为人知。此外，它还充当蛋白质糖基化和蛋白质-蛋白质交联的抑制剂。卡诺辛还被关联于缓解肌肉疲劳，并且只能被运输至活跃的肌细胞中。本路径展示了卡诺辛的主要代谢产物及其相互之间的关系。
