Heterocyclic Compounds

Ring compounds having atoms other than carbon in their nuclei per Grant and Hackh's Chemical Dictionary, the 5th edition. The heterocyclic compound family consists:

Acids, Heterocyclic:

A class of acids containing a ring structure in which at least one atom other than CARBON is incorporated. Major types as follows:

• Cinoxacin

• Indoleacetic Acids

• Isonicotinic Acids

• Isonipecotic Acids

• Nicotinic Acids

• Nipecotic Acids

• Orotic Acid

• Picolinic Acids

• Pipecolic Acids

• Xanthurenates

Alkaloids:

Organic nitrogenous bases. Many alkaloids of medical importance occur in the animal and vegetable kingdoms, and some have been synthesized. (Grant and Hackh's Chemical Dictionary, 5th ed). Major types as follows:

• 1-Deoxynojirimycin
