Fmoc-Val-OH is an N-Fmoc-protected form of L-Serine. L-Serine is a non-essential amino acid that is required for the synthesis of sphingolipids and phosphatidylserine, compounds that are important for central nervous system neuronal survival. L-Serine is also important in intermediary metabolism in eukaryotic cells.

Fmoc-Gly-OH is an N-Fmoc-protected form of Glycine. Glycine is a non-essential amino acid that acts as an inhibitory neyrotransmitter in the vertebrate central nervous system. Glycine also posesses cytoprotective effect against oxidant damage in the kidney.

Fmoc-β-alanine is an amino acid building block used in peptide synthesis. With a growing peptide drug market the fast, reliable synthesis of peptides is of great importance.
