First, the enzyme and its role
Enzyme is a protein catalyst for biochemical reactions produced by living cells and plays a very important role in the digestion and metabolism of animals. The enzymes in the biochemical metabolic pathways in vivo can be divided into six classes: oxidoreductases, transferases, hydrolases, lyases, isomerases and synthetases. Most of the enzyme preparations used in industry are hydrolases, which can be divided into amylase, protease, lipase, pectinase, xylanase, β-glucanase, cellulase, depending on the substrate. Phytase, ribonuclease, etc. The enzymes that animals can secrete into the digestive tract are mainly proteases, lipases and carbohydrate enzymes. Under the action of digestive enzymes, the substrate macromolecular substances (such as proteins, fats, polysaccharides, etc.) are degraded into small molecular substances that are easily absorbed, such as oligopeptides, amino acids, fatty acids, glucose, and the like.
Feed enzyme preparations can be roughly divided into two major categories of digestive enzymes and non-digestive enzymes. Non-digestive enzymes are enzymes that the animal itself cannot secrete into the digestive tract. These enzymes can digest substances that the animal cannot digest or degrade some anti-nutritional factors, mainly cellulase, xylanase, and β-glucanase. , phytase, pectinase, etc. Digestive enzymes are amylases, proteases, and lipases that are secreted by animals themselves.
Enzyme action characteristics: 1 high efficiency. The enzymatic reaction can be carried out efficiently under normal temperature and normal pressure and suitable pH. The catalytic ability of the enzyme is 10 million times or even hundreds of millions of times higher than that of the general catalyst; 2 substrate specificity. Enzymes are highly specific to the substrate and can only act on specific compounds, specific chemical bonds or specific chemical reactions. For example, alpha-amylase can only hydrolyze alpha-1,4 glycosidic linkages in starch, which can only be degraded by phytase.
Sepetir is a medium-weight hardwood. The colour of the heartwood is golden brown, darkening on exposure. Dark brown or black streaks are sometimes present, producing handsomely figured wood. The density is (450-)520-790(-900) kg/m3 at 15% moisture content. The grain is straight but more often shallowly interlocked, texture moderately fine and even.
