As an enthusiast who has spent considerable Vasoactive Intestinal Peptide[40077-57-4] ; Molecular Formula · C ; H ; N ; O ; Other Names · VIP (28 amino acids).Read more time reviewing the literature on peptide synthesis and molecular biology, I find the architectural complexity of this specific chain truly remarkable. By examining the structural components of this molecule, we can better appreciate its role as a 28-amino acid polypeptide and its significance in various experimental models.
The Molecular Architecture of VIP
At its core, Vasoactive intestinal peptide (VIP) is a 28-amino acid peptide that functions as a critical signaling molecule. From my personal review of the data, the molecule is defined by its precise sequence, which dictates its behavior. The VIP peptide is synthesized from a much larger precursor protein known as preproVIP, which consists of 170 amino acid residues. Through post-translational processing, the signal peptide (residues 1-20) is removed, yielding the mature, active form.
The structure of Vasoactive intestinal peptide | C147H237N43O43S - PubChem this molecule is not merely a linear sequence; it possesses a sophisticated secondary configuration. Research indicates that the mature VIP peptide is characterized by two β-turns containing the initial N-terminus eight-amino acid residues, which are then followed by two distinct helices. This folding pattern is essential for its interaction with class II G protein-coupled receptors.
