Acylated and other amphiphilic peptides are well known to self-assemble into supramolecular structures . Stearylated peptides, closely related to C18-s2s, C18-rs2s and C18-PeB GF assemble as supramolecular structures with a critical micelle concentration (CMC) between 0.8–0.9 µM and a size between 0.2 and 2.3 µm depending on the peptide concentration [12] .

The hormone name is based on its role as a growth hormone-releasing peptide, with reference to the Proto-Indo-European root gʰre-, meaning "to grow". Acyl peptide hydrolase cleaves the amyloid-beta peptide at amino acids 13, 14 and 19. In addition, by real-time PCR we found elevated acyl peptide hydrolase expression in brain areas rich in amyloid plaques suggesting that this enzyme's levels are responsive to increases in amyloid-beta levels. The invention provides a method for making polypeptides being preferentially acylated in certain lysine ϵ-amino groups. Specifically, glucagon like protein-1 (GLP-1(7-37)) is acylated. The present invention is related to a method of producing polypeptides in transformed host cells by expressing a precursor molecule of the desired polypeptide which is to be acylated in a subsequent in 8 Jun 2007 The peptide acylation pattern of GHRP-6 by hydrophilic PLGA polymers with different molecular weights was characterized by reversed-phase  Acylation of a cysteine containing peptide with palmitoyl chlroide, when attached to a solid support, followed by acidolytic cleavage of the peptide from the resin,  25 Apr 2013 The preproghrelin gene peptides include acylated ghrelin (AG), UAG and obestatin.

It stimulated the release of GH from the anterior pituitary through the GH secretagogue receptor (GHS-R). which includes N-terminal-acylated peptides. We describe the factors contributing to this instability and how to predict and control it. The instability is a function of the remote acyl group, R 2CO, four bonds away from the site of hydrolysis. Electron-rich acyl R groups accelerate this reaction.

Antimicrobial peptides may also function as metabolic inhibitors, inhibitors of DNA, RNA, and protein synthesis, and inhibitors of cell wall synthesis or septum formation. They are also known to cause ribosomal aggregation and delocalize membrane proteins.

Flow rate was 0.5 iffl/min through a Pharmacta PepRC 5/5 The acylated peptide specifically releases GH both in vivo and in vitro, and O-n-octanoylation at serine 3 is essential for the activity. We designate the GH-releasing peptide `ghrelin' (ghre is the Proto-Indo-European root of the word `grow'). Human ghrelin is homologous to rat ghrelin apart from two amino acids. The acylated peptide specifically releases GH both in vivo and in vitro, and O-n-octanoylation at serine 3 is essential for the activity.
