Digester start

Digestion starts in the mouth, where saliva breaks down starch (a complex carbohydrate) into sugar (a simple one). This is why chewing on a piece of bread for a long time makes it start to taste... 

Protein digestion starts in the mouth and continues in your stomach and small intestines. This is due to pepsin, which is secreted in the saliva and obviously the gastric juice, followed by pancreatic enzymes, then absorbed by the mucosal cells in the small intestines. In short, the digestive system breaks down protein into its peptide amino acid structures so they can be absorbed in the small intestine via the... 

The assumption must be introduced that an optimised stationary state of the cell population should continuously be distorted when biomass is taken up and digestion starts. These processes include the appearance of local concentration gradients or electric potential differences. Distortions are supposed to occur rapidly and periodically , inducing fluctuations with a decent frequency (Dq. This characterises the dynamics within the whole growing cell ensemble. Because of the... 

Protein digestion starts in the stomach where the acid secreted by the oxyntic cells both assists the denaturation of the proteins and activates the pepsinogen secreted by the peptic cells by removing about 20% of the molecule. Activation is autocatalytic exposure to the very low pH of the stomach contents also provides optimum conditions for the activity of the enzyme. Pepsin is not very specific but is most active with respect to bonds in which an aromatic amino acid...

The principle uses of Na2S04 are in the manufacture of paper, soaps, and detergents. These accounted for 65% of U.S. consumption from 1990 to 1995, representing a significant shift from 1980 when paper production alone consumed 67%. Pulp (qv) and paper consume only 25% (2). The kraft paper process uses a mixture of sodium sulfide and sodium hydroxide to digest wood chips. Both the sulfide and hydroxide are generated, starting with sodium sulfate as the raw material. 

When you eat starchy foods, they are broken down into glucose by enzymes. The process starts in your mouth with the enzyme amylase found in saliva. This explains why, if you chew a piece of bread long enough, it starts to taste sweet The breakdown of starch molecules continues in other parts of the digestive system. Within 1 to 4 hours after eating, all the starch in food is converted into glucose. 

The growth of a child, the production of polymers from petroleum, and the digestion of food are all the outcome of chemical reactions, processes by which one or more substances are converted into other substances. This type of process is a chemical change. The starting materials are called the reactants and the substances formed are called the products. The chemicals available in a laboratory are called reagents. In this section, we see how to use the symbolic language of chemistry to describe chemical reactions. 

Pancreatic enzyme supplements should be taken immediately prior to meals to aid in the digestion and absorption of food. Alternately, patients can supplement their diet with medium chain triglycerides (MCTs) or ingest foods rich in MCTs since they do not require pancreatic enzymes for absorption. An appropriate regimen incorporates the successful doses of each enzyme (amylase, lipase, and protease) from the starting non-enteric-coated regimen. As with the previous example, a patient stabilized on Viokase-8, six tablets with each meal, can be transitioned to Pancrease MT-16 three tablets with meals. The famotidine can then be discontinued. 

Symptoms of intoxication in humans caused by accidental ingestion of Kou-Wen plants have been described as follows. The effect on the digestive system starts with loss of appetite and turn of the stomach, and continues to severe abdominal pain and intestinal bleeding. The effect on the respiratory system presents as breathing difficulties which finally lead to death by respiratory failure. The effect on muscle innervation usually results in generalized muscular weakness and paralysis of the limbs. The effect on the circulatory system starts with heartbeat disorders and a drop in blood pressure, but heart failure is not a common cause of death. In addition to dilation of pupils, a drop in body temperature and proliferation of white blood cells have also been obseryed (70). 

Water content of the three samples was stable at the range of 35% to nearly 50% in the last 2 weeks before the digesting process ended. It was noticed that water started to drop since the fourth week of experiment work, which is well matched with the temperature curve (Fig. 15). 

FIGURE 7.13 Two-dimensional separation of tryptic digest of BSA in simple 2D-HPLC. Capillary monolithic silica-C18 column (0.1 mmi.d., 10 cm) was used as 2nd-D column. Mobile phase for 2nd-D gradient started with 0% B at 0.5 min, increased to 50% B at 3.3 min, to 100% B at 3.5 min, then returned to the initial condition and held for the last 0.5 min. Flow rate 3.0 pL/min in capillary, and 2 mL/min at the pump. Other conditions are similar to those for Figure 7.11 (reproduced from the reference, Kimura et al. (2004) with permission from Wiley).
