Lr3IGF-1 (Long R3 Insulin-like Growth Factor-I or Long R3IGF-I) is an 83 amino acid analog of human IGF-I that comprises the complete human IGF-1 sequence but with the replacement of an Arg for the Glu at position 3, as well as a 13 amino acid chain peptide at the N-terminus. This makes Long R3IGF-I two to three more potent than IGF-I in studies, because it has a lower affinity to be made inactive by IGF binding proteins, and as a result more possible activity in the body. The enhanced potency of Lr3IGF-1 over IGF-1 is due to the decreased binding of Long R3 IGF-1 to all known IGF binding proteins. These binding proteins normally inhibit the biological actions of IGF’s. This also will allow the peptide to have a longer half life of around 20-30 hours. Increasing the activity of biological IGF results in positive are increased amino acid transport to cells, increased glucose transport, increased Protein synthesis, decreased Protein degradation, and increased RNA synthesis.
