Mar 9 2015 · Amine-reactive reagents react with non-protonated aliphatic amine groups including the amine terminus of proteins and the ?-amino group of lysines The ?-amino group has a pK of around 10 5; in order to maintain this amine group in the non-protonated form the conjugation must take place in a buffer with slightly basic pH

What happens when an amine is converted into an alkylammoniumion?

not very soluble in water When an amine is converted into an alkylammoniumion (by the addition of acid) the ionic ammonium ion is much more effective at pulling non-polar groups(up to ~15-18 C atoms) into aqueous solution, just as was the case for carboxylate ions. They do this by forming micelles, just like the carboxylate ions.

What are amines and alkaloids?

Many amines are found in natural products and many of them are biologically active when ingested or injected. There has been a long-standing interest in these compounds and they are collectively referred to as alkaloids,because of the basic (alkaline) properties resulting from the amine group.

How do you know if an amine is secondary or tertiary?

If no gas was evolved but an insoluble yellow or orange liquid separated from the solution, then this is indicative of a secondary aliphatic or aromatic amine. If no gas was evolved and no yellow liquid separated then this is indicative that no reaction occurred and the amine tested is a tertiary amine.

Do amines have lower boiling points than alcohols?

1° and 2° amines have lower boiling points than alcohols of similar molecular weight. 3° amines, since they do not hydrogen bond to each other, have boiling points similar to hydrocarbons of the same molecular weight. Physical Properties of Amines: Boiling Points
