How are amines formed
Webpresent, such as the amines that are part of the structure of proteins in meat, or added during production (e.g., nitrates or nitrites added to meats as preservatives). Nitrosamines are formed when nitrites, which can be formed from nitrates, react with a secondary or tertiary amine. The concentration of nitrosamines tends to increase over time, WebAmines, reactions Amines are similar to ammonia in their reactions. Like ammonia, amines are basic. Like ammonia, amines are nucleophilic and react with alkyl halides, acid chlorides, and carbonyl compounds. The aromatic amines are highly reactive in electrophilic aromatic substitution. Title:
