In vitro fermentation of grain and enzymatic digestion of cereal starch
Fermentation of grain in the rumen and the digestion of starch in the small intestine are influenced by both animal and grain characteristics. Two assays were established to determine the importance of grain characteristics on fermentation and enzyme digestion. To simulate microbial fermentation in the rumen finely milled samples of grain were incubated in rumen fluid and the end products of fe...
متن کاملIn vitro Biochemical Characterization of All Barley Endosperm Starch Synthases
Starch is the main storage polysaccharide in cereals and the major source of calories in the human diet. It is synthesized by a panel of enzymes including five classes of starch synthases (SSs). While the overall starch synthase (SS) reaction is known, the functional differences between the five SS classes are poorly understood. Much of our knowledge comes from analyzing mutant plants with alte...

It is thought that digestion of hydrogen bonds results in the unwinding of the double helices of parallel α-1,4 glucan chains in the crystal lamellae of amylopectin molecules. Th...
متن کاملIn vitro starch digestion in sorghum flour from Algerian cultivars
This work aims to evaluate starch digestion in whole sorghum grains. Nine sorghum cultivars were sampled from the Sahara of Algeria. The structural characteristics of sorghum grains were measured. Total starch (TS) varied between 67.67% and 74.82%, digestible starch (DS) between 64.34% and 69.70%, and resistant starch (RS) ranged from 2.55% to 7.98%. The kinetic of starch digestion displayed fi...
متن کاملCell fate specification in the cereal endosperm.
While superficially simple, endosperm development is a complex, dynamic process. Cereal endosperms contain three major cell types: starchy endosperm, transfer cells and aleurone. The localized accumulation of the END1 transcript in the syncitial endosperm suggests that signals from the maternal placental tissue specify transfer cell type early. Aleurone fate is plastic and requires the continua...
