Peptides is a monthly peer-reviewed scientific journal covering the biochemistry, neurochemistry, pharmacology, and biological functions of peptides. It was established in 1980 and is published by Elsevier. The editor-in-chief is Karl-Heinz Herzig (University of Oulu).
The Journal of Peptide Science is abstracted and indexed by Chemical Abstracts Service, MEDLINE/PubMed, Scopus, and the Science Citation Index.According to the Journal Citation Reports, the journal has a 2021impact factor of 2.408, ranking it 66th out of 87 journals in the category "Chemistry Analytical" [1] and 255th out of 297 journals in the category "Biochemistry & Molecular Biology".
There are numerous types of peptides that have been classified according to their sources and functions. According to the Handbook of Biologically Active Peptides, some groups of peptides include plant peptides, bacterial/antibiotic peptides, fungal peptides, invertebrate peptides, amphibian/skin peptides, venom peptides, cancer/anticancer peptides, vaccine peptides, immune/inflammatory ...
A typical workflow of a peptide mass fingerprinting experiment. Peptide mass fingerprinting (PMF), also known as protein fingerprinting, is an analytical technique for protein identification in which the unknown protein of interest is first cleaved into smaller peptides, whose absolute masses can be accurately measured with a mass spectrometer such as MALDI-TOF or ESI-TOF.

When Pauling and Corey first proposed the alpha sheet, they suggested that it agreed well with fiber diffraction results from beta-keratin fibers. [2] However, since the alpha sheet did not appear to be energetically favorable, they argued that beta sheets would occur more commonly among normal proteins, [3] and subsequent demonstration that beta-keratin is made of beta sheets consigned the ...
Richard A. Houghten is a heterocyclic organic chemist and founder of the journal Peptide Research, which was later merged with the International Journal of Peptide and Protein Research, to become the Journal of Peptide Research. His work mainly concerns peptide activity and pharmacology. [1]
The connecting peptide, or C-peptide, is a short 31-amino-acid polypeptide that connects insulin's A-chain to its B-chain in the proinsulin molecule. In the context of diabetes or hypoglycemia, a measurement of C-peptide blood serum levels can be used to distinguish between different conditions with similar clinical features.
Ela is processed by removal of its N-terminus signal peptide and then secreted in the extracellular space. Its 34-aa mature peptide serves as the first endogenous ligand to a GPCR known as the Apelin Receptor. [33] [32] The genetic inactivation of Ela or Aplnr in zebrafish results in heartless phenotypes.
