Cellulose and Glycogen are biological substances.
Celluloses were a type of glycan found in plants. They were the main components of plant cell walls, and they belonged to the class of glycans found in living organisms. Glycogen was a type of branched-chain glycan formed by the combination of glucose, also known as liver glycan or glycogen. It could be divided into liver glycogen and muscle glycogen. It was an energy storage substance found in animals, and it was also a class of glycogen. Read more exciting novels for free
Biological Glycogen Knowledge Points
Glycogen (C H O)n, also known as animal starch, was a branched-chain glycan condensed from many glucose. It was a storage form of glucose in humans and animals. I. Glycogen synthesis (Glycogen Formation) 1. During the resting period after the liver completes the Colli cycle, the process of glycogen production is initiated; this process can also be initiated by hormone, such as after a sugar-rich meal, which is secreted in response to the increased blood sugar level. 2. The general process of synthesizing glycogen from glucose was as follows: glucose → glucose 6 -monophosphate → glucose 1 -monophosphate → eudPG → glycogen. II. Glycogen distribution It was mainly distributed in the liver (liver glycongen) and skeletal muscle (muscle glycongen) of animals. Glycongen was also found in some lower plants, fungi, yeasts, and bacteria. Among them, the human liver stores about 100g of glycogen (accounting for 6% - 8% of the liver weight) to maintain the stability of human blood sugar, and about 400g in skeletal muscle (accounting for about 1% - 2% of skeletal muscle weight). The molecular structure of glycogen 1. D-glucose, which was linked by alpha- 1,4 and alpha- 1,6 glycosidic bonds, could be completely digested into D-glucose with a molecular weight of 1 million to 10 million. It was a highly branched and uneven molecular. 2. The straight chain was mainly bound by alpha-1,4 giycosidic bonds, while the branched chain was bound by alpha-1,6 giycosidic bonds. Each branch contained 12 - 8 sugar residue. There was a branch every three sugar units on the main chain, and there were branches on the branches every three sugar units. The outermost branch contained about 6 - 7 sugar units. Glycogen had only one reducing end, but there were many non-reducing ends. Glycogen synthesis and digestion started from the non-reducing end. The Nature of Glycogen 1. Glycogen was a white powder with a density of 1.629g/cm 3. It was not dissolved in alcohol, but it was dissolved in hot water and reacted with iodine-producing a brownish-red color. 2. Its chemical composition is very similar to starch. Function of Glycogen 1. The main function of hepatic glycogen - It provides glucose to maintain blood sugar levels during exercise. When muscles extract glucose from the blood for the production of Ang-3, if other sources of glucose cannot be used immediately, the blood sugar level will drop. The decomposition of liver glycogen can prevent the low blood sugar caused by exercise. 2. Muscle Glycogen's Main Function - It provides glucose for the glycolysis in the muscles during exercise. The glucose produced by its decomposition remains in the muscles and provides fuel for the production of adenosinetrimonate. 3. Glycogen can also be used as an energy source for metabolism. The human body's intake of glycogen can improve the heart and blood circulation ability, and protect the liver. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Biochemical breakdown of glycogen
Glycogen decomposition was a biochemical process. In the presence of an organic phosphorus acid, it was catalyze by a Phosphorylating Acid. Phosphorylating began from the alpha-1,4 glycosidic bond at the non-reducing end of the glycogen molecules, releasing glucose- 1 -phosphorus acid until it formed limit starch. Subsequently, the glucose- 1 -phosphorous acid was converted to glucose- 6 -phosphorous acid under the catalyze of the glucose mutants. Finally, it was converted to glucose under the catalyze of the glucose- 6 -phosphorous acid in the liver. During this process, the glycogen debranching-ase also played a role. It could break the alpha-1,4-glycosidic bond between the third and fourth glycosides of the four glycosides in front of the branch point of the alpha-1,6-glycosidic bond left by the glycogen Phosphorase, move the three glycosides to the end of the other non-reducing end and connect them with the alpha-1,4-glycosidic bond. It could also make the remaining alpha-1,6-glycosidic bond connected to the glycoside to be digested. Releasing one molecular sugar. Glycogen cleavage requires glycogen Phosphorase and Debranchase. Glycogen Phosphorase has different Isozymes in skeletal muscle, liver, and brain. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The types of substances and their reactions
There were four basic types of material reactions, namely chemical reaction, decomposition reaction, displacement reaction, and metathesis reaction. A chemical reaction is a reaction in which two or more substances react to form a new substance. It usually releases energy and can be expressed as A + B + … = D. For example, the reaction of metal and oxygen to form metal compounds, the reaction of non-metal and oxygen to form non-metal compounds, and so on. The decomposition reaction is a reaction that produces two or more other substances from one substance. It usually requires energy input (such as heating or adding a catalyst, etc.), which can be expressed as A B = A + B +..., for example, the decomposition of potassium chloride-acid into potassium chloride-acid and oxygen. A substitution reaction was a reaction between a simple substance and a compound to form another simple substance and compound. It must be an oxido-reduction reaction, which could be expressed as AB + D = bb + A, such as the reaction between a metal and an acid. The metathesis reaction was a reaction in which two compounds exchanged their components to form two other compounds. The essence of the reaction was that the two substances exchanged ions in an water solution and combined to form a substance that was difficult to be ionised (weak ions such as precipitations, gases, water, etc.). It could be expressed as AB + DE = AE + DB. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Medicines are bio-active substances
Medicines were part of the active substances. Bioactive substances were all compounds that could affect life processes, including antibiotics, hormones, vitamins, minerals, etc., while drugs were special substances used to prevent, treat, and diagnose diseases. Many drugs have biological activity, such as antihistamines. When the human body comes into contact with an allergic source, the mast cells in the body release a biological active substance called histamin, which triggers an inflammation reaction. Antihistamines reduce or eliminate allergic symptoms by blocking the binding of histamin to its receptor. Another example was the drugs made from substances extracted from marine organisms, such as the glucomannan obtained from the body wall and internal organs of sea cucumber, which had significant hemostatic and anti-tumor activities. These all indicated that drugs could belong to the category of biological active substances. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Will there be thick smoke after the reaction of substances?
Thick smoke may be produced after the reaction of substances. For example, when carbon dioxide and carbon dioxide react, the carbon dioxide will be reduced to carbon, which will produce black smoke (carbon black). The reaction equation is [2MG + CO2 = 2Magnesia + C]. For example, a chemical plant in Rockdale County, George, USA, produced a large amount of smoke when it caught fire; The underground pipeline in Lianyungang, Jiangsu Province exploded and sprayed a large amount of black liquid and thick smoke; The fire scene caused by the firecrackers stored in a household in Shangqiu, Jinan, was also filled with thick smoke. The thick smoke may be produced by the chemical reaction of substances to form solid small particles, which were suspended in the air to form thick smoke. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
