Ionization of peptides
WebConsider Peptide ionization behavior • 1 free α‐amino group and 1 free α‐carboxyl group• These groups ionize but their constants are differentbecause oppositely charged groups are no longer linked tothe α‐carbon.• The other α‐amino and α‐carboxyl terminals are nowcovalently linked. Web4 uur geleden · Researchers identify a short-chain carbon circuit that enables reverse flux of pyruvate-derived acetyl CoA through medium-chain ketothiolase (MKT) to regenerate critical co-factors necessary for β-oxidation of long-chain fatty acids, thereby promoting mitochondrial lipid tolerance. Insufficient MKT flux leads to lipid-induced energy instability …
