Hydroxycinnamic acid - a natural barrier to prevent and protect free radicals

Vitamins, Fe2+, and Cu2+ are ubiquitous in organisms. The Fenton reaction produces oxygen radicals in the process of aerobic metabolism. Hydroxyl radicals (•OH) are the most active, most toxic and harmful in human active oxygen radicals. The largest free radical, which can cause oxidative damage and destruction of sugars, amino acids, proteins, nucleic acids and other substances in tissues, and cause cell necrosis or mutation. In the process of aerobic metabolism, cells can produce OH in many ways. When the body is cleared of OH, when the active substance is insufficient, accumulation of OH can directly cause destruction of cell membranes, DNA, and other biological macromolecules and cause a series of difficult diseases such as heart disease, Alzheimer's disease and Parkinson's disease. Therefore, the study of OH scavengers is of great practical significance.

Recently, the Department of Chemistry of the Medical College of Shantou University has been experimentally determined to use a p-hydroxycinnamic acid derivative in comparison with the effects of 3-OH, 2-OCH3, and 4-OCH3 used in previous tests to remove OH in vitro. The relatively clear and relatively strong ability to remove OH activity has a good preventive and protective effect on some free radical-induced lesions and injuries, effectively reducing the chance of free radicals causing difficult diseases. The use of p-hydroxycinnamic acid as a scavenger of •OH, its own biological activity, strong in anti-oxidation, anti-tumor, anti-chemotherapy, etc., also applies to other medical biological research, in the prevention and treatment of free radical lesions There has been a further breakthrough.

Agricultural Steel Buildings

How is the quality of agricultural steel structure buildings? What are the advantages of using it?
Nowadays, the application rate of agricultural steel structure buildings is still very high, and many rural families also choose this type of buildings, such as using Steel Structure Warehouse to store agricultural machinery, as a cowshed and horse shed, etc. The price is very favorable, and the cost performance is also very high. So what is the specific quality of such buildings? What are the advantages of using it?

strong security
Many people worry that the use of steel structure buildings is not safe enough and looks less stable than traditional housing, but this is not the case. The safety of agricultural steel structure buildings is still very good. It can resist earthquakes of level 8 and wind resistance of level 13. The light steel structure has high durability and good practicability. Even if it is used in some harsh environments, it is also safe.

large area
Because there are no columns inside the Steel Structure Building, the steel structure is directly used for support, and the wall thickness is low, so the internal area of the building is large and the space utilization rate is high, which can also meet the requirements of various families and factories on the internal area of the building. requirements.

High integration
Because the agricultural steel structure building is also an integrated residence, it can generally be built in a few hundred square meters in one or two months. After the construction is completed, it can be settled immediately, saving time and effort, and the cost is also very cost-effective. Most manufacturers have an integrated production model, and each component has standard specifications for processing, which is also conducive to the later construction of buildings.

Energy saving and environmental protection
The steel structure itself is made of light steel, which has a high recycling rate, and can be disassembled and installed at any time, and its long-term use is also guaranteed.

heat insulation
Steel structure buildings are constructed with extruded boards, glass county committee cotton, etc., so their thermal insulation effects are good, and they also have good sound insulation effects.

Can be customized
Agricultural steel structure buildings can be customized, and both the appearance and internal layout can be customized. When purchasing, you can directly customize according to your needs, and you can also choose different design styles by contacting the manufacturer, so that the buildings can also meet our needs. It not only has very basic living functions, but also can meet the individual needs of different consumers.
