Stearic Acid 1842

Q: The role of sugar in the human body?: Detoxification: Carbohydrate on the liver glycogen levels in the body of the resistance to toxic substances and the detoxification of certain chemical substances in the important significance.If the human body glycogen rich, the resistance to disease is strong At the same time on the carbon tetraoxide, ethanol, arsenic and other toxic substances have a strong detoxification.

Q: What are the most stable carboxylic acid derivatives?: In addition to acid halide are more stable, which ester and amide stability is stronger

Q: What is the difference between organic matter and inorganic matter?: Organic matter that organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonates, metal carbides and other rare carbon compounds excluded) or hydrocarbons and their derivatives in general. Organic matter is the material basis for life.

Q: Is acrylamide an oxygen-containing derivative of hydrocarbons?: High school stage seems to learn alcohol, phenol, aldehyde, carboxylic acid and esters and amino acids

Q: What is the meaning of organic ah, organic food on the human body what practical benefits: Chemical point of view, organic is organic matter, mainly by the carbon atoms and hydrocarbons derivatives.

Q: Calcium fatty acid is an organic or inorganic chemical: Organic chemicals. Most of the carbon compounds in addition to carbon dioxide, carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.

Q: Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons: Agree upstairs chemdraw method.

Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?: Organic this historical term, can be choked to the 19th century, when the students that organic compounds can only be biological (life-force, vis vitalis) synthesis. This theory is based on organic matter and "inorganic" the basic difference, organic matter can not be non-vitality synthesis. But later this theory was overthrown, the German chemist Friedrich W?hler to cyanide and ammonia synthesis of urea (inorganic synthesis of organic matter). In general, organic compounds are defined as compounds with hydrogen bonds and inorganic compounds are not. Therefore, carbonic acid (H2CO3), carbon dioxide is an inorganic compound, but formic acid (also known as formic acid) (HCOOH, the first fatty acid) is an organic compound.

Q: Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?: Hydrocarbons and hydrocarbon derivatives

Q: The nature and use of cellulose derivatives: Starch can be used as a diluent, binder, disintegrant, and can be used to prepare dextrin and starch pulp. Chemical experiments with amylose test iodine. Of course, as a plant energy storage material can also eat. Organic derivatives such as rayon, cellophane and nitrates, acetate and the like, and ether derivatives such as methylcellulose, ethylcellulose, carboxymethylcellulose and polyanionic cellulose are prepared on the basis of textile and papermaking. Raw material is used as a dietary fiber.
