Dietary accumulation and metabolism of polybrominated diphenyl ethers by juvenile carp (Cyprinus carpio) Polybrominated diphenyl ethers (PBDEs) are hydrophobic organic contaminants with properties and nomenclature similar to polychlorinated biphenyls (PCBs).

Nomenclature of Ethers The International Union of Pure and Applied Chemistry (IUPAC) has set some rules and standards innaming organic compounds. These rules will be followed in naming ethers. Step 1: Identify the longest carbon chain and highlight it as the parent chain. There are always two...
This chapter focuses on heterocyclic compounds that have small (three-membered and four-membered) and large (seven-membered, eight-membered, and larger) rings and discusses their possible structures, nomenclature, properties, and tautomerism. An overview of structures and naming of three- and four-...
IUPAC nomenclature – Ester names are derived from the parent alcohol and therefore the parent acid, where the latter could also be organic or inorganic. Esters which forms from the only carboxylic acids has commonly more traditional names, known as “trivial names”. For example of acetate, for...
this group has continued to design new EPI-001 analogs that target the NTD and are currently under clinical development for human study179. More high-throughput screens have been used to identify new classes of compounds, such as the glycerol ethers niphatenones isolated from the sponge Niphates...
The molecular structure illustrates the proton nomenclature and the colour-coded relative degrees of saturation of individual non-overlapping protons. The STD amplification factors were normalised to the intensity of the signal with the largest STD effect. The reference STD spectrum (top) with proton ...
The melamine structure represents the ring ofcarbonand nitrogen. Therefore, it is called a heterocyclic ring. This ring exists in a hexagonal form. The double bonds in this heterocyclic ring are arranged alternately. Therefore, it shows resonance. Three main groups are attached to carbon. These ...
It may be useful to describe at this point the severalstereoregularconfigurations, which are observed in polymer chains. The possible regular structure ofpoly-α-olefinswas recognised byNatta et al. (1955), who devised a nomenclature now accepted to describe stereoregular polymers of this type.Fig...
Most prefix and infix functional replacement nomenclature The following functional classes: acetals, acids, alcohols, amides, anhydrides, anilides, azetidides, azides, bromides, chlorides, cyanates, cyanides, esters, di/tri/tetra esters, ethers, fluorides, fulminates, glycol ethers, glycols, hemiace...
