IGF-I (24-41)

IGF-I (24-41) (Insulin-like Growth Factor I (24-41)) is amino acids 24 to 41 fragment of IGF-I. IGF-I, a 70 aa polypeptide hormone, is a trophic factor for both neurons and glial cells. IGF-I is partly responsible for systemic growth hormone (GH) activities. IGF-I has anabolic, antioxidant, anti-inflammatory and cytoprotective actions. IGF-I (24-41) regulates somatic growth and behavioral development[1][2][3].
