Description
IGF-I LR3
Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1). IGF-1 LR3 inhibits the movement of glucose into the body’s cells which facilitates fat burning and the use of fat in the body for the production of energy. It differs from native IGF-1 in that it possesses an arginine instead of a glutamic acid at the third position in its amino acid sequence (“arginine 3”), and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN) (“long”), for a total of 83 amino acids (relative to the 70 of IGF-1). The consequences of these modifications are that IGF-1 LR3 retains the pharmacological activity of IGF-1 as an agonist of the IGF-1 receptor, has very low affinity for the insulin-like growth factor-binding proteins (IGFBPs), and has improved metabolic stability. As a result, it is approximately three times more potent than IGF-1, and possesses a significantly longer half-life of about 20–30 hours (relative to IGF-1’s half-life of about 12–15 hours). The amino acid sequence of IGF-1 LR3 is MFPAMPLSSL FVNGPRTLCG AELVDALQFV CGDRGFYFNK PTGYGSSSRR APQTGIVDEC CFRSCDLRRL EMYCAPLKPA KSA.
