Peptide synthesis

The chemical process of creating peptides by linking amino acids together. Can be performed in solution or on solid phase. Commercial peptides are almost exclusively made via solid-phase peptide synthesis (SPPS).

Frequently Asked Questions

What is Peptide synthesis?
The chemical process of creating peptides by linking amino acids together. Can be performed in solution or on solid phase. Commercial peptides are almost exclusively made via solid-phase peptide synthesis (SPPS).
Why is Peptide synthesis important in peptide research?
Peptide synthesis is a foundational concept in peptide science. Understanding peptide chemistry helps researchers and practitioners evaluate peptide quality, predict stability, and make informed decisions about storage, reconstitution, and formulation.

Related Terms

Solid phase synthesis

A method of peptide synthesis where the growing peptide chain is attached to an insoluble resin bead. Amino acids are added one at a time, enabling automation and high throughput. Developed by Robert Bruce Merrifield (Nobel Prize, 1984).

Peptide bond

A covalent chemical bond formed between the carboxyl group of one amino acid and the amino group of another through a condensation reaction. Peptide bonds link amino acids into peptide chains.

Purity percentage

The proportion of the desired peptide in a sample, determined by HPLC analysis. Research-grade peptides are typically 95–98% pure; pharmaceutical-grade exceeds 99%. Higher purity reduces the risk of adverse reactions.
