Isoform
A naturally occurring variant of a peptide or protein that differs slightly in amino acid sequence but retains similar function. Different isoforms may have different tissue distributions or activity levels.
Frequently Asked Questions
What is Isoform?
A naturally occurring variant of a peptide or protein that differs slightly in amino acid sequence but retains similar function. Different isoforms may have different tissue distributions or activity levels.
Why is Isoform important in peptide research?
Isoform 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.

Analog
A synthetic peptide with a modified amino acid sequence compared to the natural version, designed to improve potency, stability, or half-life. Semaglutide is an analog of natural GLP-1 with 94% sequence homology.
Amino acid sequenceThe specific linear order of amino acids in a peptide chain, written from N-terminus to C-terminus. The sequence determines the peptide’s three-dimensional structure and biological activity.
