While starch and fat digestion can be carried out satisfactorily without the help of pancreatic enzymes, the proteases are critical to proper protein digestion. Incomplete digestion of proteins creates a number of problems for the body including the development of allergies and formation of toxic substances produced during putrefaction. Putrefaction refers to the breakdown of protein material b...

Digestion of isolated fat cells, fat cell membranes, and liver cell membranes with phospholipase C and phospholipase A from various sources leads to a 3to 6-fold increase in the specific binding of 12sI-insulin to receptors in these structures. Calcium is required for digestion with phospholipase A, and digestion with phospholipase D is without effect. In contrast to the studies with insulin, t...

Micro-scale isolation of sulfated glycopeptide from tissue was achieved by successive application of pronase digestion (Step 1), cetylpyridinium chloride-fractionation (Step 2), crude heparinase digestion or chondroitinase ABC digestion plus nitrous acid treatment (Step 3) and preparative cellulose acetate membrane-electrophoresis (Step 4). By this method, sulfated glycopeptide was obtained in ...

The present study of a typical proteolytic enzyme extends the quantitative investigations previously reported from this laboratory on the effects of pressure on protein systems in viva (1) and in vitro (2). This paper presents new data on the self-digestion of trypsin and the digestion of casein by trypsin; a forthcoming paper will discuss the effects of temperature and hydrostatic pressure on ...

Food consists of a complex group of substances that differ in chemical composition and physical structure. Collectively these substances form a matrix and it is the behaviour of this matrix which determines the digestibility, the rate and extent of nutrient release, from a food during normal gut transit. In the process of digestion both chemical and physical degradation of food occurs. Chemical...

Digestion in the USA Business Analysis of Anaerobic Digestion in the USA Market conditions are looking increasingly favourable for the growth of the anaerobic digestion industry in the US. While this form of biogas production has historically been limited to agricultural and wastewater uses, it is growing in favour as a method of managing and extracting value from food wastes. The feasibility o...

Anaerobic digestion is a well-established biological process for converting biomass in waste streams into a renewable energy source, and it also contributes to the treatment of these waste streams. In this introductory mini-review, some fundamental aspects of anaerobic digestion for use in the pulp and paper industry and other sectors are briefly summarized. The contents include the basics of a...

• The process of starch assimilation in the ruminant is complex and remains an avenue by which increases in production efficiency can be gained. • Ruminal starch digestion is typically 75 to 80% of starch intake. Starch that escapes fermentation and flows to the small intestine may be more resistant to enzymatic digestion. On average, 35 to 60% of starch entering the small intestine is degraded...

The process of sludge digestion using hydrogen peroxide as the only oxidizing agent was carried out. It was pointed out that the application of H2O2 to the digestion process is possible provided that aerobic conditions of the process are strictly controlled in the course of the process. Since H2O2 should be added frequently into the digestion chamber it is highly recommended to supply the diges...

Mature Angus steers were intraruminally infused with base to increase ruminal pH. Base infusions, increasing rumen pH from 5.8 to 6.2, did not change duodenal pH but tended to reduce fecal pH. Increased ruminal pH tended to increase digestion of fiber (9 percent) but reduced ruminal digestion of starch by 18 percent (P> .05). Ruminal pH and ruminal starch digestion were negatively correlated (P...
