This classification is based on its molecular structure and function within the human bodyIGF-1 (Insulin-like Growth Factor 1) is a peptide hormone that plays a critical role in growth, development, and cellular repair..

IGF-1 is a relatively small molecule, consisting of approximately 70 amino acids.Insulin-Like Growth Factor 1 (IGF1) peptide Its molecular weight is around 7649 Da (Daltons)Interaction of a viral insulin-like peptide with the IGF-1 .... This structure is similar to insulin, featuring an A and B chain connected by disulfide bonds. The sequence of amino acids dictates its biological activityIGF-1 Peptide Mimetic-functionalized Hydrogels Enhance .... Various forms and analogues exist, such as IGF-1 LR3, which is a lab-made version with an extended structure, including 13 extra amino acidsToo much of a good thing: the health risks of human growth hormone. These modifications can alter its potency and duration of action.

The term peptide refers to a short chain of amino acids linked by peptide bonds. As IGF-1 is composed of amino acids, it fits this definition perfectly. It is also referred to as insulin-like growth factor 1 (IGF-1), highlighting its structural and functional similarity to insulin, although it is distinct作者：E Altindis·2018·被引用次数：98—We have identified 16 different human peptide hormones/growth factors, including fourinsulin/insulin growth factor (IGF)1-like peptides(VILPs) that have .... Furthermore, the igf1 gene is responsible for producing mature IGF-I and also generates different forms through alternative splicing, including carboxy-terminal extensions known as E-peptides. These E-peptides play a role in isoform-specific gene expression and can control the bioavailability of IGF-1.

The biological significance of IGF-1 extends across various stages of life作者：BK Brisson·2012·被引用次数：69—The Igf1 gene encodesmature IGF-I and a carboxy-terminal extension called the E-peptide. In rodents, alternative splicing and post-translational processing .... In children, it is a primary mediator of growth hormone (GH) effects, stimulating the growth of cells and tissues. In adults, IGF-1 continues to play a crucial role in cellular repair and has anabolic effects, including the stimulation of muscle protein synthesis and promotion of muscle growth. This makes IGF-1 a key factor in maintaining muscle mass and facilitating recovery.

Beyond its role in natural growth and repair, IGF-1 has garnered attention for its potential applications and associated risks. Its ability to promote muscle growth and fat loss has led to its exploration in areas like aesthetic and anti-aging medicine. However, the powerful biological activity of IGF-1 peptides necessitates caution. The side effects of IGF-1 peptides can be significant, and their use is monitored by organizations like the USADA (United States Anti-Doping Agency) due to concerns about performance enhancement.

It's important to distinguish IGF-1 from other related compounds. While it shares similarities with insulin and is influenced by human growth hormone (HGH), it is a distinct molecule with its own receptor interactions. IGF-1 interacts with both the IGF-1 receptor and, to some extent, the insulin receptor. Researchers are even exploring viral insulin/IGF-1-like peptides which, despite structural similarities to insulin and IGF-1, can inhibit IGF-1 receptor signaling.

In summary, IGF-1 is unequivocally a peptide. Its classification as an anabolic peptide hormone and polypeptide growth factor accurately reflects its composition and profound impact on growth, development, and cellular processes. Understanding the nature of IGF-1 as a peptide is essential for comprehending its physiological functions and potential implications in various biological and medical contexts.作者：DM Irwin·2018·被引用次数：2—Structural modeling suggested that these VILPs have three-dimensional structures similar to insulin andIGF-1.
