The polypeptide Long R3 Insulin-like Growth Factor-I (igf-1lr3) is an 83 amino acid analog of igf-1lr3 actually comprising the complete igf sequence but with the substitution of an Arginine (Arg) for the Glutamic Acid (Glu) at position 3, as well as a 13 amino acid extension peptide. This sequence change causes igf-1 lr3 to avoid binding to proteins and allow it to have a much longer half life, around 20-30 hours. This analog of igf has been produced with the purpose of increasing the biological activity of the igf peptide.igf stands for insulin-like growth factor. Among the effects the most positive are increased amino acid transport to cells, increased glucose transport, increased protein synthesis, and decreased protein degradation. When igf is active it behaves differently in different types of tissues. In muscle cells proteins and associated cell components are stimulated. Protein synthesis is increased along with amino acid absorption. As a source of energy, igf-1lr3 mobilizes fat for use as energy in adipose tissue. In lean tissue, igf-1lr3 prevents insulin from transporting glucose across cell membranes. As a result the cells have to switch to burning off fat as a source of energy. igf-1lr3 builds new muscle tissue by promoting nitrogen retention and protein synthesis. This causes the growth of muscles through both hyperplasia (which is an increase in number of muscle cells) and mitogenesis (which is the actual growth of new muscle fibers). Thus igf-1lr3 not only makes muscle fibers bigger, it makes more of them as well. Therefore, igf can actually change the genetic capabilities in terms of muscle tissue and cell count. igf increases and differentiates the number and types of cells present.
