A vegetable fiber from tomato which can be used in making functional meat and bakery foods
...en that fibre is an ingredient that has beneficial physiological
effects (preventing and protecting against a number of illnesses in the body). That is, fibre enrichment principally augments the added value of foodstuffs nutritionally. Likewise, the use of tomato fibre creates products with new sensorial attribu...
Sphingolipids with therapeutic ends
...ny kind of infection or traumatic event. This is a physiological
process called apoptosis. Certain sphingolipids also regulate this process. Why is this important? Imagine a metabolic dysfunction or alteration that causes the growth of a tumour. Perhaps the advance of this can be detained by adding certain sphin...

Virtual duck bills demonstrate species coexistence
... is that each species has evolved morphological or physiological
traits that allow it to exploit some resources more efficiently than all other species. Such partitioning of resources essentially provides each species with exclusive access to resources necessary for its survival. Although coexistence is often attr...
