Description

Nα-Boc-L-histidine is an N-Boc-protected form of L-Histidine. L-Histidine is an essential amino acid that plays an important role in mitochondrial glutamine transport and has potential of abolishing oxidative stress caused by brain edema.L-Histidine promotes zinc uptake in human erythrocyes and also has potential as an antioxidant therapy for acute mammary inflammation in cattle.
