Whether you are looking at the basic alanine unit or the more complex L-alanyl-L-ala We report solution-state and solid-state 13C NMR data for the alanine dipeptide (N-acetyl-l-alanine-N'-methylamide, AcAlaNHMe) in polycrystalline, nine structure, the precision of chemical notation provides the roadmap for our investigations.
The Chemical Foundation
When we discuss the alanine dipeptide, we are typically referring to a molecule composed of two alanine units linked by a peptide bond. The standard molecular formula: C6H12N2O3 serves as the primary identifier for this compound. From my own notes, I often cross-reference this with the linear formula: CH3CH(NH2)CONHCH(CH3)CO2H. This linear representation is particula L-Alanyl-L-alanine | C6H12N2O3 | CID 5484352 - PubChem rly helpful when visualizing the condensation reaction that joins the amino acids.
It is worth noting the distinction between this and other related structures. For instance, while C3H7NO is often associ A common alanine dipeptide-based torsion potential does in fact lead to excellent agreement between protein simulations and PDB structures. ated with the monomeric units, the dipeptide requires the inclusion of the amide linkage. I have also encountered references to larger structures like Ala-Ala-Ala, which is a tripeptide consisting of three L-alanine units joined by peptide linkages, demonstrating how the chain length significantly alters the physical properties of the substance.
