Peptide Glossary

Peptide

A short chain of amino acids linked by peptide bonds.

Amino Acid Sequence

The specific order of amino acids that defines the chemical structure of a peptide.

Peptide Bond

The chemical bond linking amino acids within a peptide chain.

Lyophilisation (Freeze-Drying)

A process used to remove moisture under vacuum to improve stability during storage and transport.

Purity (>99%)

A measure of the target compound's proportion in a sample, typically assessed by analytical techniques such as HPLC.

HPLC

High-Performance Liquid Chromatography — an analytical method commonly used to assess purity and identity.

Mass Spectrometry (MS)

An analytical method used to confirm molecular weight and assist with identity verification.

In-Vitro Research

Experimental work conducted outside a living organism, such as in cell cultures or test systems.

Stability

The ability of a compound to maintain structure and integrity under defined conditions over time.

Degradation

Chemical changes that reduce integrity, such as hydrolysis or oxidation.

COA (Certificate of Analysis)

A document providing analytical verification such as purity and identity testing.
