The recombinant protein expression system in Escherichia coli is often used for this purpose. This method allows for the cost-effective production of recombinant peptides that are otherwise difficult to synthesize chemically.
Synthetic peptides are typically made using solid-phase peptide synthesis (SPPS), where peptides are assembled by sequentially adding amino acids to a growing chain attached to a solid resin. This method is highly efficient for producing short to medium-length peptides and allows for precise control over the peptide sequence.
The process of making a peptide involves either chemical synthesis or recombinant DNA technology. Chemical synthesis, such as SPPS, builds peptides amino acid by amino acid. The recombinant method involves genetic engineering to express the desired peptide in microbial cells, ensuring high yield and purity. Synthesis and purification are crucial for obtaining the final product.
The body produces peptides by breaking down proteins during digestion or by synthesizing them directly from amino acids in cells. Enzymatic processes within cells assemble amino acids into peptides, like how a factory assembles parts into a finished product. Active peptides are crucial for numerous bodily functions, including hormone regulation and immune responses.
