  • Description


    Fmoc-Ser(tBu)-OH  CAS 71989-33-8


    Fmoc-Ser(tBu)-OH is white or off-white solid at normal temperature and pressure, which is insoluble in water but soluble in acetate. Fmoc-Ser(tBu)-OH is often used as a biochemical synthesis reagent, and is mostly used in the structural modification and synthesis of polypeptide drug molecules and bioactive molecules. Omizzur peptide is supplying high-purity Fmoc-Ser(tBu)-OH from stock, which can be delivered worldwide.


    What is Peptide Synthesis?

    Peptide synthesis is a solid-state synthesis sequence that generally starts from the C-terminal (carboxyl end) to the N-terminal (amino end). Peptide synthesis can generally be divided into two types: solid-phase synthesis and liquid-phase peptide synthesis.


    Fmoc-Ser(tBu)-OH is a serine derivative. Amino acids and amino acid derivatives have been commercialized as energy supplements. They affect the secretion of anabolic hormones, fuel supply during exercise, mental performance during stress-related tasks, and prevent muscle injury caused by exercise. They are considered as beneficial dietary substances.
