The book also has a selection of short biographical entries for people who have made im- portant contributions to the field. There are a number of appendixes, in- cluding structural information on carboxylic acids, amino acids, sugars, and nitrogenous bases and nucleosides. There is also a ...

The best known (regulated) DBPs are small molecules: trihalomethanes, haloacetic acids, N-nitrosodimethylamine, bromates, etc. Their cytotoxicity, genotoxicity, and carcinogenicity for mammalian cells have been studied, and maximum permissible concentrations (MPCs) have been established [3, 6–12]....
At the present time, this will mean that the definition encompasses a range of compounds that includes hydrocarbons (Vichi et al., 2007b), aldehydes and ketones, alcohols, esters; furans and carboxylic acids (Luna et al., 2006). Some compounds such as hydroxytyrosol are sufficiently volatile ...

These molecules are particularly important in biochemistry, where this term refers to alpha-amino acids with the general formula H2NCHRCOOH, where R is an organic substituent. Specification: Amino acid: 50%min Solubility: 100% Moisture: 5%max Nitrogen: 18.2 Crude protein:...
Chemical formulae (compounds) and their reactions produce the field of organic chemistry. As in language, the vocabulary of organic chemistry has to be learned. These are the formulae or rather the compounds in organic chemistry. In addition, hundreds of named reactions or mechanisms have to be...
