Lipid intermediates were first detected in studies on the biosynthesis of lipopolysaccharide and of proteoglycan in bacteria. These intermediates turned out to be sugar derivatives of poly-isoprenoid alcohols. A series of these compounds has been isolated from various organisms. Their general formula is shown as follows ... 

Some of the most important organic compounds in biochemistry are the a ammo acids rep resented by the general formula shown... 

Mercury. The fkst successful use of mercury as a fungicide occurred in 1913 (8). The fkst seed treatment compound developed was chloro(2-hydroxyphenyl)mercury [90-03-9] (1). Subsequentiy, a number of organic mercury derivatives having general formula RHgX have been used. 

Ketones are a class of organic compounds that contain one or more carbonyl groups bound to two aUphatic, aromatic, or aUcycbc substituents, and are represented by the general formula... 

The peroxides are a group of compounds with the general formula R-O-O-R . All peroxides are hazardous materials, but the organic peroxides may be the most hazardous of all. 

The organic bases form, like ammonia, crystalline chloroplati-nates with platinic chloride of the general formula BoH,j,PtCl,). By estimating the amount of platinum present in the salt, it is possible to calculate the molecular weight of the platinum compound, and consequently that of the base. 

Mercaptans are organic sulfur compounds having the general formula of R-S-H. As stated earlier, amine treating is not effective for the... 

Asymmetrical triesters of phosphoric acid of the general formula ROPO (OR,)2 (R = C8 i4 alkyl R, = C, 3 alkyl) were obtained in approximately 70% yield by treatment of a higher fatty alcohol and a Ci 3 alcohol with P0C13 in hexane or pyridine at <0°C. The products were soluble in nonpolar organic solvents and partially soluble in polar organic solvents and water. But the foamforming ability and foam stability of the compounds in water were low [11]. 

Write the general formula of each of the following types of compounds, using R to denote an organic group (a) amine (b) alcohol (c) carboxylic acid (d) aldehyde. 

Like mercury, tin is a metal that has a tendency to form covalent bonds with organic groups. The compounds to be discussed here are tributyl derivatives of tetravalent tin. The general formula for them is... 

For even more convenience in representing the structures of organic compounds, particularly in printed material, line formulas are used, so-called because they are printed on one line. In line formulas, each carbon atom is written on a line adjacent to the symbols for the other elements to which it is bonded. Line formulas show the general sequence in which the carbon atoms are attached, but in order to interpret them properly, the permitted total bond orders of all the respective atoms must be kept in mind. Again referring to the compounds (a) to (e) described above, the line formulas are as follows ... 

The alkane series is also called the saturated hydrocarbon series because the molecules of this class have carbon atoms connected by single bonds only, and therefore have the maximum number of hydrogen atoms possible for the number of carbon atoms. These substances may be represented by the general formula C H2,I + 2 and molecules of successive members of the series differ from each other by only a CH2 unit. The line formulas and names of the first 10 members of the series, given in Table 21-2, should be memorized because these names form the basis for naming many other organic compounds. It should be noted that the first parts of the names of the later members listed are the...
