What are heterocyclic amines?
A chemical that is formed when meat, poultry, or fish is cooked at high temperatures, such as frying, broiling, and barbecuing. Heterocyclic amines are carcinogens (substances that may cause cancer). Also called HCA.
What are heterocyclic aromatic amines?
Heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) are chemicals formed when muscle meat, including beef, pork, fish, or poultry, is cooked using high-temperature methods, such as pan frying or grilling directly over an open flame (1).
What causes heterocyclic amines?
Heterocyclic amines (HCAs) are the carcinogenic and mutagenic chemicals formed from cooking muscle meats such as beef, pork, fowl, and fish. HCAs form when amino acids and creatine react at high cooking temperatures and are formed in greater quantities when meats are overcooked or blackened.
What heterocyclic means?
Definition of heterocyclic : relating to, characterized by, or being a ring composed of atoms of more than one kind.
Which two are a pair of heterocyclic amines?
The other two nucleobases, adenine and guanine, are also heterocyclic amines called purines; they are composed of a fused pyrimidine and imidazole.
What is the structure of heterocyclic?
A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). Heterocyclic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of these heterocycles.
What is heterocyclic and examples?
Heterocyclic definition Of or relating to a compound containing a closed ring structure made of more than one kind of atom. Pyridine (C5 H5 N), for example, is a heterocyclic compound, as its ring contains five carbon atoms and one nitrogen atom.
What are the applications of heterocyclic compounds?
Heterocyclic compunds have a wide range of application. They are predominantly used as pharmaceuticals, as agrochemicals and as veterinary products. They also find applications as sanitizers, developers, antioxidants, as corrosion inhibitors, as copolymers, dye stuff.
How many types of heterocyclic compounds are there?
Based on the electronic arrangement, we can classify Heterocyclic compounds into two types: Aliphatic Heterocyclic Compound. Aromatic Heterocyclic Compound.
Why are heterocycles important?
Thus, heterocycles have critical importance for medicinal chemists, because using them, it is possible to expand the available drug-like chemical space and drive more effective drug discovery programs.
