homocarnosine

ho·mo·car·no·sine

(hō'mō-kar'nō-sēn),
N2-(4-aminobutyryl)-l-histidine; a constituent of the brain formed from l-histidine and γ-aminobutyric acid.

homocarnosine

/ho·mo·car·no·sine/ (-kahr´no-sēn) a dipeptide consisting of γ-aminobutyric acid and histidine; in humans it is found in brain tissue only.

homocarnosine

[hō′mōkär′nōsēn]
a dipeptide consisting of gamma-aminobutyric acid and histidine. In humans it is found in the brain but not in other tissues.

Specifically, although under appropriate conditions both isoforms catalyze the hydrolysis of the dipeptide carnosine ([beta]-alanyl-L-histidine), only serum carnosinase is able to hydrolyze homocarnosine ([gamma]-aminobutyryl-L-histidine) (2, 9,10).
It is believed that carnosine and homocarnosine have the ability to protect neuronal cells against ischemic injury (11) and oxidative stress (12,13) as well as to increase their resistance toward functional exhaustion and accumulation of senile features (14).
