Q:What are the nature of sugar
Carbohydrates, also known as carbohydrates, are the most abundant and most widely distributed organic compounds in nature. Mainly by the carbon, hydrogen, oxygen composition. Glucose, sucrose, starch and cellulose all belong to carbohydrates.
Q:Artemisinin is not a derivative of hydrocarbons
Artemisinin is a colorless needle-like crystal obtained from the compound inflorescences Artemisia annua L., which is (3R, 5aS, 6R, 8aS, 9R, 12S, 12aR ) - octahydro-3,6,9-trimethyl-3,12-oxo-12H-pyran [4,3-j] -1,2-benzodiazepine-10 (3H) -one. Molecular formula for the C15H22O5.
Q:China's largest asphalt production base where
Oil asphalt is the residue after distillation of crude oil. According to the degree of extraction of different, at room temperature into a liquid, semi-solid or solid. Oil asphalt color black and shiny, with a high temperature. Because it is in the production process has been distilled to 400 ℃ or more, and thus contain little volatile components, but there may still be high-molecular hydrocarbons without volatile, these substances are more or less harmful to human health.
Q:1. What are liquid hydrocarbons?
1. A hydrocarbon containing five to eight carbons 2. Not, it is an oxygen-containing derivative of a hydrocarbon 3. A hydrocarbon and a halogenated hydrocarbon (unsaturated) polymer, an alcohol, a phenol and
Q:What cells are composed of compounds
Protein and water
Q:Carboxylic acid and carboxylic acid
The carboxylic acid can not react with the carboxylic acid, which is esterified with a hydroxyl alcohol, for example, acetic acid (acetic acid) reacts with ethanol (alcohol) to produce ethyl acetate with a special flavor.
Q:The role of sugar in the human body?
Toxicity: Carbohydrate is the main source of heat, each carbohydrate can provide 4 kcal of calories. Carbohydrates in the exercise after oxidation, the final product for the carbon dioxide and water, the body without any harm. The brain needs glucose As the only energy source, if the blood glucose levels decline, there will be low blood sugar, the brain adversely affected.
Q:Compare the difference between London smoke and Los Angeles photochemical smog
Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.
Q:What is a derivative of a hydrocarbon? What is an aromatic hydrocarbon derivative?
Hydrocarbon derivatives include derivatives of linear and aromatic hydrocarbons such as chloroethane bromopropane bromobenzene
Q:Are all carbon compounds all organic?
Not organic matter that is 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.
