Peptide Synthesis: What Is It?
Peptide synthesis refers to the process of making peptides, characterized by establishing a peptide bond between two amino acids. Although relatively inefficient production procedures slowed the early stages of peptide synthesis, developments in chemistry and technology have led to dramatically better synthesis methods. Synthetic peptides have been and will continue to be critically important to current scientific and medical advancements, and this is only expected to increase as the study of peptides expands.
The Synthesis of Peptides.
Two amino acids are joined to form a peptide during synthesis. Typically, this is achieved by joining one amino acid’s amino group (N) to the carboxyl group (C) of another amino acid. Peptide synthesis proceeds C-to-N, in contrast to the N-terminus-to-C-terminus connection required for protein production.
Twenty amino acids (including arginine, lysine, and glutamine) are found in nature, but many more have been created. This natural source opens up a wealth of options for developing novel peptides. However, amino acids contain several reactive groups that might adversely interact during the synthesis process, resulting in undesirable truncating or branching of the peptide chain or inadequate purity or yield. Therefore, peptide synthesis is a complex procedure requiring experience and skill.
Certain reactive groups in amino acids must be deactivated or prevented from reacting to assure the intended output from the synthesis process and to avoid unwanted, unneeded reactions. Because of this need, scientists have developed tailored chemical groupings. We may classify these so-called “protective groups” into three types:
N-terminal protecting groups: These groups shield amino acids’ N-termini from oxidation. Temporary protective groups are readily eliminated to speed up the process of peptide bond formation. As N-terminal protecting groups, start-butoxy carbonyl (Boc) and 9-fluorenylmethoxycarbonyl (Fmoc) are often used.
C-terminal protective group: A group that shields the amino acid’s C terminus is called a C-terminal protective group. Liquid-phase peptide synthesis requires C-terminal protecting groups, whereas solid-phase peptide synthesis does not.
Permanent protective group: Since amino acid side chains are very reactive, peptide synthesis necessitates the addition of specific protective groups to shield the side chains from involuntary reactions. Permanent protective groups on side chains can withstand the synthesis’s multiple iterations of chemical treatment. After peptide production is complete, only powerful acids can eliminate.
Methods of Peptide Synthesis
Solution phase synthesis was the first technique used to create peptides (SPS). Solid-phase peptide synthesis (SPPS) has essentially overtaken SPS. However, it still has specific applications, such as large-scale peptide manufacturing. Since SPPS has several benefits, including high yield, purity, and speed of manufacturing, it is becoming more popular.
The use of microwaves in SPPS synthesis allows for even more significant improvements to the synthesis process. Synthesizing lengthy peptide sequences is very helpful since it increases yield and processing speed. However, the price of microwave-assisted SPPS might be higher than that of standard SPPS.
Even while peptide synthesis methods such as SPPS boast impressive purity and yield standards, flaws and blemishes may crop up. Because more steps are required to synthesize a more extended peptide sequence, the probability rises as the peptide sequence becomes longer. Therefore, specific methods of purification are used to guarantee the highest quality. Reverse-phase chromatography (RPC) and high-performance liquid chromatography (HPLC) are examples. Purification techniques based on the physiochemical characteristics of peptides are used to isolate the target peptide from unwanted contaminants. The RPC technique is now the gold standard for purifying peptides.
The Benefits of Synthetic Peptides
Peptides are essential components of biological research, and peptide synthesis continues to drive global scientific advancement. Numerous pharmaceutical firms have taken notice of peptides because of their medicinal potential. Several medications derived from peptides have been approved by the FDA and are now on the market. Peptides are an expanding field of biochemical study because of their high efficiency, selectivity, and low toxicity in pharmaceutical and diagnostic applications.
