Carbonyl

Some of the research suggests that there are harmful chemicals that are inhaled while vaping, such as carbonyls like formaldehyde, which can have many adverse effects on the human body. For example, one of the main components of e-liquids, propylene glycol, has been known to cause respiratory irritation and ocular inflammation (Arnold, 2014). Also, those…

pentose sugars plus ribitol/glycerol/other sugar alcohols) and capsule can also be composed of phosphoesterases. Capsule is also made of repeating oligonucleotide of more than one monomer. Many exopolysaccharides are acidic in nature due to heavy carbonyl groups either from acidic sugars such as uronic acids/neuraminic acid or from non-sugar subunits such as pyruvyl, acetyl and formyl group.Capsules are either synthesized at the level of cell membrane or extracellularly as done by Streptococcus…

with thiamine used as the base catalyst of the reaction. The next step was the preparation of benzil from the oxidation reaction of benzoin with nitric acid. In the oxidation reaction, the alcohol functional group of benzoin was oxidized to form the carbonyl functional group of benzil, while the nitric acid was reduced into a mixture of nitrogen oxides that formed toxic brown fumes. The final step was the preparation of tetracyclone from the aldol condensation reaction of…

The one located at 1730.1 cm was the result of a carbonyl group and -1 the peak at 1617.7 cm-1 specified the existence of a benzene ring. Another peak at 1151.5 cm-1 indicates a C—O bond, which is presented in methyl m-nitrobenzoate. The peak at 739.9 cm indicated that the product was meta-substituted…

Temazepam, commonly known as Restoril, is a sleeping pill that is prescribed to patients. This drug is classified under a type of drugs called benozaphines, which are, “a large group of drugs with sedative and anxiety-reducing properties, which have been found valuable for a large number of uses” (UXL Encyclopedia of Drugs and Addictive Substances). This class of drugs is used to reduce anxiety and help with insomnia. Since temazepam is classified as a benzodiazepine, I was curious as to what…

A Chinese pharmacist named Hon Lik, created E-cigarettes in 2003 (Grana et al. 6). E-cigarettes use a liquid in its chamber that uses a battery to create a spark that combusts inside the barrel to create smoke (Grana et al. 6). Many consumers that use e-cigarettes are using them as a way to end their smoking habits of tobacco products (Franck et al. 1945). E-cigarettes seem to be a growing trend in use among people that are trying to quit smoking. Therefore, e-cigarette companies are trying to…

INTRODUCTION The trends in physical properties of organic compounds such as boiling points and melting points can be deducted from their structures, including size (molecular weight, surface area), shape and functional groups. These factors significantly influence the strength of the intermolecular forces of attraction present; and the nature and strength of intermolecular forces determine the variations in boilingpoints of organic compounds. The boiling point of a liquid is the temperature at…

Polymer - A word, which is connote for large molecules (that a molecule made from simple repeating units called monomers). The monomers are main building block of polymers. Polymers play an essential and ubiquitous role in everyday human life because of the extraordinary range of properties. Polymers are among the most widely used and important type of materials today. Polymers have been with us from the beginning of time; they form the very basis (building blocks) of life. Animals, plants all…

when it comes to your home, will explain the harmful vapors of e-cigarettes. In a paper written by Goniewicz et. al. of the largest study involving the emissions of an e-cigarette. “In this paper the chemical emissions of 11 chemicals, including carbonyl compounds, volatile organic compounds, tobacco specific nitrosamines, and heavy metals were measured from 12 different e-cigarettes. Each e-cigarette was tested three times” (Offermann 38-39). When smoking an e-cigarette it’s different from…

Coordination complex A coordination compound is the result of the reaction of lewis acid and lewis base in which neutral molecules called ligands make coordinate covalent bond with middle metal atom. Ligands have one electron pair to donate to a metal atom and are called complex agents. • Metal atoms are Lewis acids because they can accept pairs of electrons from Lewis bases. • Within a ligand, the atom that is directly bonded to the metal atom/ion is called the donor atom. • A coordinate…
