However, the world of RGD peptides extends beyond this simple tripeptide. Researchers often utilize modified or longer peptide sequences incorporating the RGD motif to enhance targeting capabilities or study specific biological interactionsPeptide Calculator - Bachem. This leads to variations in the molecular weight. For instance, a commonly studied RGD peptide known as GRGDNP exhibits a Molecular Weight, 614.61. This particular RGD peptide is recognized for its role as an integrin inhibitor, highlighting the functional significance of its specific sequence and resulting molecular weight. Another example is the RGD peptide (GRGDNP) (TFA), which has a Molecular Weight: 728RGD peptide (Arg-Gly-Asp) | Tripeptide | CAS 99896-85-2.63, likely due to the addition of a trifluoroacetic acid (TFA) salt.
The structure of the RGD peptide can also influence its molecular weight. Cyclic forms of RGD peptides, such as cyclic RGD (with a Molecular Weight of 612.7 g/mol) or Cyclo (RGDfC) (with a Molecular Mass/Weight of 578.7), involve a covalent bond that closes the peptide chain. This cyclization alters the overall molecular weight and can significantly impact the peptide's stability and binding affinity to its target receptors, particularly integrinsRGD(Arg-Gly-Asp)Peptides;Formula.

The molecule itself, in its various forms, is a subject of extensive research.
Furthermore, the context in which the RGD peptide is presented can affect its stated molecular weight. For example, when conjugated to other molecules or polymers, the overall molecular weight will increase substantially. Studies have explored RGD-Substituted High Molecular Weight Hyper-Branched Polymers, indicating that the molecular weights of these conjugates can vary widely depending on the polymer backbone and the degree of RGD substitution. Similarly, research on RGD peptide-based materials may report on polymers with a range of molecular weights, such as those with low dispersity and precise chain ends, as seen in studies involving RAFT polymerization.

For the basic RGD peptide, the Formula is C12H22N6O6, leading to the 346.34 valueRGD-Substituted High Molecular Weight Hyper-Branched .... For the GRGDNP sequence, the Molecular Formula is often cited as C23H38N10O10, corresponding to the Molecular Weight: 614.61.
In summary, while the foundational RGD peptide has a molecular weight of 346.34 g/mol, the actual molecular weight of RGD peptides can vary significantly based on modifications, cyclization, conjugation, and the presence of counterions. Understanding these variations is essential for precise experimental design and accurate interpretation of results in fields ranging from cell biology to drug delivery and biomaterials science. The exploration of RGD peptides continues to expand, underscoring the importance of detailed knowledge regarding their chemical properties, including their molecular weights.
