In the world of biochemistry and peptide research, nomenclature is the foundation of precision. When exploring the glycine alanine dipeptide name, one quickly encounters the systematic conventions used to describe these fundamental molecular building blocks. As an enthusiast of peptide research, I have found that grasping the structural dynamics of these compounds is essential for anyone interested in the synthesis and analysis of short-chain peptides.
Nomenclature and Chemical Identity
The molecule formed by the condensation of glycine and L-alanine is most commonly referred to as Glycyl-L-alanine. In formal chemical literature, you will often find it listed with the identifier CID 1551643 or under the CAS number 3695-73-6. When we discuss the names and specific dipeptide configurations, it is helpful to use the standard three-letter abbreviations: Gly-Ala.
The naming convention follows a simple rule: the amino acid providing the carboxyl group retains its full name, while the one providing the amino group is converted to an "yl" suffix. Thus, when glycine acylates alanine, the resulting dipeptide glycylalanine is the standard nomenclature. If the order were reversed, the product would be alanylglycine.
Structural Characteristics and Variations
My personal journey into understanding these structures began with looking at the glycine-alanine dipeptide at a molecular level. The reaction is a classic example of dehydration synthesis, where a peptide bond is formed between the nitrogen of the alanine amino group and the carbonyl carbon of the glycine.
Beyond the basic dipeptide, researchers often look at related compounds to understand structural properties. For instance:
* Glycylglycine (Gly-Gly): Peptides & Proteins A simple dipeptide often used as a standard in laboratory settings.
* Methylglycine: Al Peptide Bond Formation between Glycine and Alanine so known as sarcosine, this is a derivative of glycine.
* Glycyl-L-alanine hydroiodide monohydrate: A specific crystalline form that has been studied for its unique structural arrangement.
In my experience, comparing these with other sequences—such as ala-leu, ala-lys, ala-gly, ala-pro, ala-tyr and ala-phe—highlights how the side chain of the second amino acid profoundly influences the chemical behavior of the entire chain.

The significance of these dipeptides extends into advanced materials science and str Jun 23, 2019 — How many dipeptides are possible by the reaction of glycine and alanine? Glycine has no chiral centre. Alanine has one chiral centre. The products uctural biology. For example, the glycine-alanine dipeptide repeat has been the subject of intensive study regarding protein aggregation and amyloid formation. Furthermore, the development of poly(dl-alanine-co-glycine)s represents an effort to create peptide-based analogues for various material applications.
When analyzing the formation of these molecules, it is important to remember the distinction between chiral and achiral components. Glycine is unique because it lacks a side chain and is achiral, whereas alanine possesses a chiral center. This structural nuance is critical when determining the potential stereoisomer Ala-Leu 3303-34-2 s formed during synthesis.
