As a naturally occurring peptide first identified in sleep-associated studies, it is commonly evaluated for how it may influence circadian signaling patterns, neurochemical balance, and recovery-related cellular activity in controlled environments
The upregulated urea cycle removes -amyloid and ammonia on one hand, while on the other, overproduction of the urea cycle metabolite ornithine leads to the overexpression of the enzyme ornithine decarboxylase 1 (ODC1), which produces excessive putrescine that subsequently degrades into GABA, H 2 O 2 and ammonium (see previous section)
