Alkaloids are often classified according to the nature of the nitrogen-containing structure e. Isoquinoline alkaloid biosynthesis, pathway ec Alkaloid bebas bersifat basa karena adanya pasangan elektron bebas pada atom N-nya. Berdasarkan hal tersebut, maka alkaloida dapat dibedakan atas tiga jenis utama, yaitu: Biosintesis alkaloid juga melibatkan reaksi rangkap oksidatif fenol dan metilasi.

Alkaloid tanpa atom nitrogen yang heterosilikDimana, atom nitrogen tidak terletak pada cincin karbon tetapi pada salah satu atom karbon pada rantai samping. The Journal of Biological Chemistry ; The biological activity of many alkaloids is often dependent on the amine function being transformed into a quaternary system by protonation at physiological pH values.

There have been studies that show the biosynthesis of 22 of these nitrogenous metabolites. Reaksi utama yang mendasari biosintesis senyawa alkaloid adalah reaksi mannich antara suatu aldehida dan suatu amina primer dan sekunder, dan suatu senyawa enol atau fenol.

Plant Physiology ; 81 1: Molecular Plant ; 3 1: Alkaloid kebanyakan ditemukan pada Angiospermae dan jarang pada Gymnospermae dan Cryptogamae.
