Fmoc-Aib-OH (Fmoc-alpha-aminoisobutyric acid) is an
Fmoc-protected amino acid building block for Fmoc/tBu solid-phase peptide
synthesis (SPPS). Also known as Fmoc-2-methylalanine. Aib (α-aminoisobutyric
acid) promotes helical conformation and resists enzymatic cleavage, a feature
of several incretin-type peptides. ApiSyn supplies it within a broad protected
amino acid range, so peptide programmes can source building blocks from one
manufacturer.
