An interesting recent study of a phospholipid-nucleoside conjugate [30] shows the possibility of spontaneous formation in water of super-helical strands. These structures are of interest with regard to the origin of life, as they can function as templates for polymerisation of nucleic acids. We observe that the helicoid is a zero cur ature surface with the different relevant and seemingly necessary properties also possessed by cubosomes catalytic effects, etc. These helical assemblies are therefore alternatives to cubosomes as candidates of prebiotic assemblies, crucial to the first level of evolution. In any case, two-dimensional hyperbolic forms certainly offer many features essential to the most primitive forms of life. 

Isoniazid, U5P. Isonicotinic acid hydru/.ide. isonicoti-nyl hydrazide. or INH (Nydrazid) (K curs as a nearly culoi-less crystalline solid that is very soluble in water. It is prepared by reacting the methyl ester of isonicotinic acid iih hydrazine. 

Codeine Sulfate, USP. Ctxleine sulfate is prepared by neutralizing an aqueous suspension of codeine with diluted sulfuric acid and then effecting crystallization. It cK Curs us white cry.stals. usually needle-like, or as a white cry.stalline powder. The salt is efflorescent and light sensitive. It is. soluble in water (1 30. 1 6.S at 80°). much less soluble in alcohol (1 1.280). and insoluble in ether or chloroform. This salt of codeine is prescribed frequently but is not as suitable os the pho.sphate for liquid preparations. Solutions of the sulfate and the phosphate are incompatible with alkaloidal reagents and alkaline sub.stances. 

Niacin, U5P. Niacin, nicotinic acid, 3-pyridine carboxylic acid, vitamin Bi. iK-curs as white crystals or as a cry.stal-linc powder. It is odorless or may have a slight odor. One gram of nicotinic acid dissolves in 60 mL of water. It is freely soluble in boiling water, boiling alcohol, and solutions of alkali hydroxides and carbonates but is almost insoluble in ether. A % aqueous solution has a pH of 6. Nicotinic acid has a pK of 4.85. Nicotinic acid is stable under normal. storage conditions. It sublimes without decomposition. 

It is prepared by the reaction of sodium or potassium thiocyanate with chloroformic acid methyl ester, and the intermediate product reacts with o-phenylene diamine to form the thiophanate. Thiophanate-methyl is a colourless, crystalline compound hardly soluble in water. It forms unstable salts and complexes with bivalent ions in alkaline solutions. The range of action of each thioallophanic acid derivative is identical with that of the benzimidazole derivative into which it is converted in the plant. Thiophanate-methyl has both a preventive and a curative action. 

Most molecules are at peace with themselves. Bottles of sulfuric acid, sodium hydroxide, water, or acetone can be safely stored in a laboratory cupboard for years without any change in the chemical composition of the molecules inside. Yet if these compounds are mixed, chemical reactions, In some cases vigorous ones, will occur. This chapter is an introduction to the behaviour of organic molecules why some react together and some don t, and how to understand reactivity in terms of charges, orbitals, and the movement of electrons. We shall also be introducing a device for representing the detailed movement of electrons—the mechanism of the reaction—called the curly arrow. 

The hydrolysis reaction is preferably carried out under alkaline conditions. Acid hydrolysis can lead to undesired side reactions and also incomplete reaction. Hydrolysis by water under pressure is also incomplete, especially in the case of aromatic polyurethanes. Alkaline hydrolysis in glass containers can give large amounts of silicate which interfere with subsequent analysis, and for this reason the use of steel or even nickel-coated steel containers is recommended. The hydrolysis of polyester urethanes yields the diamine from the diisocyanate, and the acid salt and glycols from the polyester. Hydrolysis of polyether urethanes yields the diamine and the polyether. If diamines are used as curatives then two diamines will be present in the hydrolysis products. 

Peat is formed when dead vegetation is saturated with water which prevents the action of aerobic bacteria. Thus, most of the carbon of the cellulosic matter is retained, and with ageing, peat is formed. It accumulates at an average rate of 0.7 mm/year or worldwide at 210 Mt of carbon. Canada (40%) and Russia (36%) have more than 3/4 of the world s peat land (320 Mha or 150 x 10 Mt of carbon). In Russia, peat deposits occupy about 1/10 of the total country s terrain. It is a spongy watery mass when first obtained from the peat bog. Six toimes of dry peat yield about 1 t of fuel. A commercial grade of peat contains about 25% water. Air-dried peat has a heating value of about 16.3 MJ/kg. Peat is rich in bitumens, carbohydrates, and humic acids, and as a chemical source, it can yield waxes, paraffins, resins, and oils. Peat also is a source of pharmaceutical and curative preparations as well as a livestock-feed supplement.
