| The majority of photosensitive molecules have a heterocyclic ring structure similar to that of chlorophyll or hemoglobin. |
|
| Cooking meats at high temperatures creates chemicals called heterocyclic amines that are otherwise not present in uncooked meats. |
|
| Thermolysis of such heterocyclic diethyl malonates results in the loss of one ester group by elimination of ethene and carbon dioxide. |
|
| The nucleotides found in cells are derivatives of the heterocyclic highly basic, compounds, purine and pyrimidine. |
|
| Unlike hydrocarbon based aromatics, which react most readily with electrophiles, perfluoro-aromatics and heterocyclic ring systems react better with nucleophiles. |
|
| These are apparently mixtures of closely related compounds that were identified in 1961 as derivatives of the heterocyclic compound phenoxazine. |
|
| Additionally, monascus pigments, purpurin, chlorophyllin and curcumin were reported to inhibit the mutagenicity of heterocyclic amines and other carcinogens. |
|
| Coumarin belongs to the heterocyclic class of organic compounds, because its molecule contains a ring of atoms of more than one element. |
|
| Mousiness Some strains of Lactobacillus and Oenococcus oeni can produce aromatic heterocyclic bases that cause a distinctive mousy flavour. |
|
| Also included are heterocyclic amine compounds, which are formed when meats and eggs are cooked or grilled at high temperatures and also found in cigarette smoke. |
|
| Pyrazole, any of a class of organic compounds of the heterocyclic series characterized by a ring structure composed of three carbon atoms and two nitrogen atoms in adjacent positions. |
|
| Purine, any of a class of organic compounds of the heterocyclic series characterized by a two-ringed structure composed of carbon and nitrogen atoms. |
|
| Thiazole, any of a class of organic compounds of the heterocyclic series characterized by a ring structure composed of three carbon atoms, one nitrogen atom, and one sulfur atom. |
|
| It is a member of the family of heterocyclic compounds, which are characterised by an unsaturated nucleus consisting of four carbon atoms and one oxygen atom. |
|
| It is a permanent authority, dealing with basic research in chemistry and biochemistry of saccharides, enzyme systems and heterocyclic compounds having biological activity. |
|
| These include Nnitrosamines, polycyclic aromatic hydrocarbons, chloropropanols, ethyl carbamate, furan, heterocyclic aromatic amines and amino acid pyrolysates. |
|
| Ionic liquids typically comprise an organic, primarily nitrogen-containing but also phosphorus-containing, mainly heterocyclic cation and an inorganic anion. |
|
| They are biologically active compounds with aliphatic, aromatic, or heterocyclic structures. |
|
| Cooking meat at high temperatures has been linked to cancer-causing chemicals called heterocyclic amines. |
|
| First, research has shown that high-heat grilling can convert proteins in red meat, pork, poultry, and fish into heterocyclic amines. |
|
|
|
| This basic structure is comprised of two benzene rings linked through a heterocyclic pyran or pyrone ring in the middle. |
|
| They detail the biochemical reactions involved in the biodegradation of major aliphatic, carbocyclic aromatic, and heterocyclic compounds. |
|
| It contains phenolic, aromatic, heterocyclic, and polycyclic organics, and inorganics including cyanides, sulfides, ammonium and ammonia. |
|
| The prompted the author to use 2,6-bis cyclohexanone as key intermediate in the synthesis of series of heterocyclic compounds. |
|
| The latter substituted with various amino acids, carbocyclic, and heterocyclic groups, generates libraries from which synthetic ligands can be selected. |
|
| In fact, aspirin and all aspirin-like analgesics, including indomethacin and sulindac, which are derived from a heterocyclic organic compound known as indole, inhibit prostaglandin synthesis and release. |
|
| Furan, any of a class of organic compounds of the heterocyclic aromatic series characterized by a ring structure composed of one oxygen atom and four carbon atoms. |
|
| For example, we recognize that heterocyclic chemistry and asymmetric synthesis are the two most complex and intriguing branches of organic chemistry. |
|
| Carvacrol has antioxidative properties, so we are thinking that it binds to, or reacts with, some of the intermediates and prevents them from forming the heterocyclic amines. |
|
| This eventually produces many important classes of flavour compounds including furans, pyrazines, pyrroles, oxazoles, thiophenes, thiazoles and other heterocyclic compounds. |
|
| The 2000 to 50,000 number-average molecular weight polymer contains monocyclic heterocyclic groups such as diketopyrrolopyrrole, squalene, or carotene. |
|
| In addition, both oxygen and nitrogen heterocyclic hydrocarbons, such as parent and alkyl homologues of carbazole, quinoline, and pyridine, are present in many crude oils. |
