disaccord

Chitinase forming strain is a kind of special microorganisms . this strain can utilize chitin as carbon source to survive and repoduce . and it has the common biochemical ch aracteristics of secreting chitinase . chitinase can degrade chitin into chitin oligosaccharide , chitin disaccharide , and chitin monosaccharide . the application of chitinase and chitin oligo saccharide on plant resistance are extensively reported . moreover researches verified that c hitin oligosaccharide can promot the growth of plant . so chitinase froming strain is a kin d of promising fungi - resistant microorgnanism . therefore , it ' s a very meaningful work to d o more extensive and deeper researches in this respect 而幾丁質酶和幾丁寡糖在植物抗病上的應用已經被廣泛的報道,而且有研究證實幾丁寡糖還能促進植物的生長發育。幾丁質酶產生菌是一類很有前途的抗真菌的微生物,因此,在這方面作更廣泛更深入的研究是很有意義的工作。

[ objective ] heparin is linear polysaccharides consisting of repeating disaccharide unit backbones of n - acetyl - d - glucosamine that is linked to d - glucuronic acid . the disaccharide repeat unit can be modified to include n - and o - sulfation ( 6 - o and 3 - o sulfation of the glucosamine and 2 - o sulfation of the uronic acid ) . these specific sulfate patterns are involved in the interaction of heparin with other molecules [目的]肝素是由n -乙酰葡萄糖胺與d -葡萄糖醛酸以1 4糖苷鍵連接起來的重復二糖單位組成的線性多糖,葡萄糖胺可帶有n -硫酸基團,可在c6上形成0 -硫酸酯,帶有硫酸基團的獨特結構參與了肝素與其他分子的相互作用。

In health food , the disaccharide and trisaccharide has various functions as recuperating blood pressure , reducing cholosterol , increasing immunity and improving water retention of food . in agriculture , it can be used as adjusting agent for plant growing and new biological pesticide 日用化工上,可作為固發及護發劑,也是塑料紡織印染彩色膠片等工業中多種定型劑固色劑粘合劑穩定劑等助劑中不可少的輔料

Hyaluronic acid ( ha ) is a high molecular weight linear polysaccharide composed of repeating disaccharide units of d - glucuronic acid ( glclia ) and n - acetyl - d - glucosamine ( glcnac ) linked by 3 - 1 - 3 and p - 1 - 4 glycoside bonds 透明質酸( hyaluronicacid )是一種由葡萄糖醛酸( glcua )和n -乙酰氨基葡萄糖( clcnac )以- 1 - 3和- 1 - 4糖苷鍵相連的二糖單位重復構建而成的,具有生物相容性的高分子聚合物。
