19. Early History of Chromatography

Author

ZECHMEISTER, L.

Abstract

RECENTLY, Drs. H. Weil and T. I. Williams made the following statements with reference to D. T. Day's investigations1: “L. Zechmeister's opinion that Day ‘might in favourable circumstances have been successful in the elaboration of chromatographic procedures’ seems, therefore, rather less than just [my italics], for Day conforms closely to that author's definition of chromatography …”. The above comments refer to a recent progress report2in which I have devoted half of the first page to Day's work, since I consider it, as well as Gilpin's papers (written under Day's influence), as typical of chromatographic experiments.

27. Some Stereochemical Aspects in Genetics

Author

ZECHMEISTER, L. and WENT, F. W.

Abstract

IT is a fundamental concept in modern chemical genetics that a separate gene is responsible for each step in the enzymatic biosynthesis of a given compound. Since in vitro the precursor (or precursors) of the compound would also be able to produce substances other than that formed in the tissue, a gene, as is well known, displays a chemical steering power which is directed toward a single structural target.

31. Spontaneous Isomerization of Lycopene

Author

ZECHMEISTER, L. and TUZSON, P.

Abstract

DURING some experiments with benzene extracts of various fruits, it was observed that the calcium hydroxide chromatogram frequently, but not in every case, shows a rather brownish orange layer below the lycopene zone. Subsequent experiments have proved that this behaviour of carefully purified lycopene depends on the time which elapses between the dissolution and the adsorption analysis. A fresh solution forms a uniform chromatogram, but if the liquid has been kept at 20° for 1–2 days, the new polyene (“neo-lycopene”) is observed ; it then forms a very distinctly separated zone in the chromatogram developed with benzene and light petroleum (3: 1). The pigment content of this layer reached 3 per cent of the total lycopene in experiments of 24 hours duration; the absorption maxima are 511, 479·5, 450 mµ in benzene and 498·5, 468, 440 mµ in petroleum ether. When the benzene solution is kept at room temperature, neo-lycopene is partly transformed into lycopene (or into a very similar dye which cannot be separated from lycopene in the column).

38. Chitin Content of the Mandible of the Snail (Helix pomatia)

Author

TÖTH, G. and ZECHMEISTER, L.

Abstract

THE presence of chitin in the above-mentioned organ has been indicated so far by means of colour reactions only, probably owing to the lack of material. During the course of another investigation, we came into the possession of 650 mandibles (1 gm.), and an acetolytic breakdown experiment was carried out. After boiling with dilute alkali and hydrochloric acid, the remainder weighed 70 mgm., and yielded upon the application of Bergmann's method 8 mgm. of colourless needles which were identical with octa-acetyl chitobiose: m.p. 290°, nitrogen content 4.4 per cent. The experiment shows that the presence of chitin can be proved in even minute amounts of natural substances.

40. Selective Accumulation of Lipochrome

Author

ZECHMEISTER, L., TUZSON, P., and ERNST, E.

Abstract

IT is well known that different animals deal with carotenoids derived from vegetable sources in various ways. The adipose tissue of the horse and the cow contain considerable amounts of polyene-hydrocarbons (carotenes), but it does not accumulate polyene-alcohols (xanthophylls). A precisely opposite selection would appear to take place in the fat of the hen.
