Transfructosidation in extracts of the tubers of Helianthus tuberosus L

Transfructosidation in extracts of the tubers of Helianthus tuberosus L.

The silage specimens on which data are reported were from grass and grass-clover mixtures ensiled during the summer of 1950 on various farms in the northeast of Scotland, and were taken at random from specimens being analysed here. It is seen from Fig. 2 that the lactic acid content of silage falls rapidly with rise ofpH. This is in accordance with the generally held view that in silage of pH g...

The action of hydrolytic enzyme system from Helianthus tuberosus L. on carbohydrates present in the tubers.

Spermidine Uptake by Mitochondria of Helianthus tuberosus.

In the present work evidence is provided that spermidine, a polyamine largely present in plant tissues, may be transported, at physiological concentrations, into the matrix space of mitochondria isolated from tubers of Helianthus tuberosus L. cv OB1 (Jerusalem artichoke). It is concluded that the movement of spermidine strictly depends on membrane potential, since it is drastically blocked by v...

Recovery of inulin from Jerusalem artichoke (Helianthus tuberosus L.) in the small intestine of man.

The recovery of inulin, a naturally occurring beta (2-->1)-fructan isolated from Jerusalem artichoke (Helianthus tuberosus L.), in the small intestine of man was studied in ileostomy subjects. The ileostomists were given a low-dietary-fibre diet based on white wheat bread and virtually free of inulin, and the same diet with the addition of 10 g and 30 g inulin product respectively, and the reco...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
