槲皮酮的化学构成是什么？如何区分黄酮、黄烷什么的之间的关系？
本人为纯种文科生，如今遇到难事，要写一篇关于化学与健康的论文。。。实在是苦啊%&_&%暂时选择了写一种叫做槲皮酮的东东。。。查到的文献能看懂的都是它的功效，对这种物质的化学构成神马的论文都看不懂啊求一个简单的介绍。。。求区分黄酮、黄烷什么的之间的关系。。。完全hold 不住的孩子要哭了。。。
理性的有机物
换题目写吧，既然不是毕业论文之类的，应该是课外作业神马的那就不要找自己不明白的领域如果主体只是化学与健康，那范围很广啊，选神马槲皮酮的，写了也没人看在果壳问答、各大主流网站里找些热点，比如苹果皮打蜡、不合格胶囊、皮鞋果冻神马的好写多了，看的人也多异噻唑啉酮 _百度百科

Isothiazolinones
Molecular weight: 115.16
Properties:　Isothiazolinones is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) and 2-methyl-4-thiazoline-3-ketone (MI). The bactericidal effect of Isothiazolinones is carried out through breaking the bond between bacteria and algae protein. When contacted with microbes, Isothiazolinones can quickly inhibit their growth, thus leading to death of these microbes. Isothiazolinones has strong inhibition and biocidal effects on ordinary bacteria, fungi and alga, and has many advantages such as high biocidal efficiency, good degradation, no residual, safety in operation, good compatibleness, good stabilization, low cost in operation.
Isothiazolinones can mix with chlorine and most cation, anion, and non-ionic surfactants. When used at high dosage, its biosludge stripping effect is excellent.
Isothiazolinones is a kind of fungicidal with properties of broad spectrum, high efficiency, low toxicity and non-oxidative, it is the ideal biocidal in industrial circulating cool water system and in wastewater treatment in oilfield, papermaking, pesticide, cutting oil, leather, detergent and cosmetics etc..
Specification:　Notes: 2%, 4% and 8% or any concentration can be supplied on demands.

Usage:　When used as sludge stripper for grade II, the dosage of 150-300mg/L is preferred, when used as boicide, the dosage of 80-100mg/L is preferred, and charges every 3-7 days. No used together with oxidative fungicidal such as chlorine, and no used in cooling water system containing sulfur. When used together with quaternary amine, the effect will be better. When used as industrial fungicide, the dosage of 0.05-0.4% is preferred.
Package and Storage:　25kg in plastic barrel, or confirmed by clients. Storage for ten months in room shady and dry place.
Safety Protection:　Corrosive, Avoid contact with eye and skin, Wear splash resistant safety goggles and rubber glores.once contacted, flush with water.
