Morin reaction

Color reactions are more or less clearly defined reactions of the substances with suitable reagents. Substance-specific reactions are not usually available, e. g. many compounds with aromatic skeletons give both a positive Vitali-Morin reaction [1 -4] and a positive Marquis reaction [4]. Again, numerous aldehydes react with electron-rich compounds in acidic medium to yield colored substances (cf. Chapters 2 and 3.1).

Photooxidation of the dGuo-5 -lysine ester leads to Z cross-linked to the lysine moiety (Morin and Cadet 1995), indicating that DNA-protein cross-links may also occur via such a process in case this amino acid happens to be in a proper position for the reaction to proceed.
