Guano

In addition to the indicated total world reserves of about 21 x 10 t having P2 s content of at least 30%, and the 9.1 x 10 ° t classified as resources, there are about 250 x 10 t of reserves and resources derived from guano which are not included in Table 14. 

Uric acid is a product of the metabolism of tire animal organism. It is usually prepared from guano, which is ticatcd first with dilute hydrochloric acid to remove phosphate of calcium. The uric acid is then dissoh ed out with hot caustic soda and the clear alkaline solution piecipitated with acid.

While metal-nitrogen and metal-oxygen bonded compounds dominate nucleobase coordination chemistry, examples in which metal-carbon bonds are formed have been identified. Early studies on the synthesis of metal-labeled DNA demonstrated that nucleotide-triphosphates, UTP, CTP, dUTP, and dCTP, can undergo mercury modification at C5 (82,83). The UTP derivative was also shown to act as a substrate for RNA polymerase in the presence of mercaptans (83). Later, guano-sine was shown to undergo mercury modification at C8 though, in this case, the purine was multiply substituted, 21 (84). 

The fact that Germany depended on imported fertilizer more than any other country gave it a special stake in the problem, too. The industrialization of Germany s sugar beet and potato farms was intimately linked to its use of natural fertilizer, especially nitrogen compounds from marine bird manure imported from Peru, Chile, and Bolivia. Yet experts predicted that Europe would exhaust South America s guano in 30 years. 

Several complexes that involve intercalation of an acridine in a portion of a nucleic acid have been studied by X-ray crystallographic techniques. These include complexes of dinucleoside phosphates with ethidium bromide, 9-aminoacridine, acridine orange, proflavine and ellipticine (65-69). A representation of the geometry of an intercalated proflavine molecule is illustrated in Figure 6 (b) this is a view of the crystal structure of proflavine intercalated in a dinucleoside phosphate, cytidylyl- -S ) guano-sine (CpG) (70, TV). For comparison an example of the situation before such intercalation is also illustrated in Figure 6 (a) by three adjacent base pairs found in the crystal structure of a polynucleotide (72, 73). In this latter structure the vertical distance (parallel to the helix axis) between the bases is approximately...
