Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the risk of food poisoning due to the presence of biogenic amines in meals made from chicken meat consumed by children under 3 years of age

Food Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Biogenic amines are low molecular weight organic bases that come from the enzymatic decarboxylation of amino acids. They are present in many types of food, with the highest concentrations usually found in fish and their derived products, as well as in beverages and fermented foods of plant, meat and dairy origin.

Visible‐Light Mediated Functionalization in Phe‐Containing Peptides Upon a Debenzylative Amination Process

Advanced Synthesis &Catalysis, Volume 368, Issue 6, 17 March 2026.
Selective late‐stage modification of N‐terminal phenylalanine short peptides is achived by visible‐light initiated reaction with N‐iodoimides in a debenzylation–amination process. This metal‐free method permits the incorporation of N‐containing heterocycles into the α‐position of the peptide backbone.

Binding of Ions to Oligopeptides

Biophysical Journal, 1973
A model for the binding of ions to oligopeptides, in which nearest neighbor interactions are considered is developed. Equations for the titration curves are derived The apparent association constants are determined as a function of the degree of polymerization and of the interactions between nearest neighbors.

Ab initio simulations of Cu binding sites in the N-terminal region of PrP [PDF]

, 2006
The prion protein (PrP) binds Cu2+ ions in the octarepeat domain of the N-terminal tail up to full occupancy at pH=7.4. Recent experiments show that the HGGG octarepeat subdomain is responsible for holding the metal bound in a square planar coordination.
