Cyanogenesis under Digestive Conditions

Cyanogenesis in Indiangrass Seedlings

In a study of seedlings of 72 entries representing 39 species, 14 genera, and 2 tribes of grasses, only entries of the genus Sorghastrum were found to contain the cyanogenic glucoside, dhurrin [f$)-/>-hydroxymandelonitrile /3-D-glucopyranoside], Dhurrin was found in seedlings of each of the 10 entries of indiangrass [Sorghostrum nutans (L.) Nash] and the three entries of $. pellitum. Seedlings ...

Comparative Fatty Acids Profiles of Flexopecten Glaber Digestive Gland under Starvation and Monoalgal Diet Conditions

The starvation effects on the fatty acids composition of the digestive gland of the scallop Flexopecten glaber were underwent in this study. Results show that food deprivation induces a diminution of the amounts of the EPA (C20:5n-3) and the DHA (C22:6n-3) as well as the n-3/n-6 ratio. Meanwhile, a selective retention, in terms of increase of percentage, of the AA (C20:4n-6) in unfed specimens ...

Prevalence of selected chronic digestive conditions.

Interaction between chitosan and oil under stomach and duodenal digestive chemical conditions.

Chitosan, the N acetylated derivative of chitin, has an effect on the absorption of dietary lipids, but there is not enough scientific knowledge about the mechanism. To study the interaction between chitosan and oil, the action of this biopolymer has been evaluated through an experimental model of the stomach and duodenum tract, although the enzimatic activity had not been evaluated. We microsc...

Cyanogenesis in plants and arthropods.

Cyanogenic glucosides are phytoanticipins known to be present in more than 2500 plant species. They are regarded as having an important role in plant defense against herbivores due to bitter taste and release of toxic hydrogen cyanide upon tissue disruption, but recent investigations demonstrate additional roles as storage compounds of reduced nitrogen and sugar that may be mobilized when deman...
