Application

二羟基丙酮是一种重要的化工原料、医药中间体和功能添加剂。其用途主要分为2 类: 直接用途和间接用途( 化学中间体) 。

Two hydroxyacetone is an important chemical raw material, pharmaceutical intermediate and functional additive. Its uses can be divided into 2 main categories: direct and indirect uses (chemical intermediates).

直接用途

Direct use

二羟基丙酮是一种天然存在的酮糖, 具有生物可降解性, 可食用且对人体和环境无毒害, 是一种具有多功能的添加剂, 可用于化妆品、医药和食品行业。

Dihydroxyacetone is a natural ketose, which is biodegradable, edible and non-toxic to human body and environment. It is a multi-functional additive and can be used in cosmetics, medicine and food industry.

用于化妆品工业

Used in cosmetic industry

二羟基丙酮主要用作化妆品的配方原料, 尤其作为防晒霜有特殊效果, 能阻止皮肤水分的过度蒸发, 起到保湿、防晒和防紫外线辐射的作用 。另外, DHA 中的酮官能团可与皮肤角蛋白的氨基酸和氨基基团起反应形成褐色聚合物, 使人们皮肤产生一种人造褐色, 所以还可用作日晒肤色的模拟剂, 得到看起来与长时间暴露于太阳光下所得结果一样的棕色或棕褐色的皮肤, 使其看上去很美。

Dihydroxyacetone is mainly used as a cosmetic ingredient, especially as a sunscreen with special effects, can prevent excessive evaporation of skin moisture, play a moisturizing, sunscreen and anti-ultraviolet radiation role. In addition, the ketone functional groups in DHA react with the amino acids and amino groups of skin keratins to form brown polymers, which produce an artificial brown on the skin. Therefore, DHA can also be used as a skin simulator to obtain brown or brown skin that looks like the result of prolonged exposure to sunlight. It looks beautiful.

提高猪的瘦肉率

Raising lean meat percentage of pigs *

二羟基丙酮是糖代谢的中间产物, 在糖代谢过程中起着重要作用, 具有降低猪体脂肪的作用, 提高瘦肉率。日本科技人员经过试验证明, 在猪饲料中加入一定量的DHA 和丙酮酸盐( 钙盐) 的混合物( 按3：1的重量比配合) , 能减少猪背肉的脂肪含量12%~ 15%, 腿肉和背最长肌肉的脂肪含量也相应减少, 蛋白质含量增高。

Two hydroxyacetone is an intermediate product of carbohydrate metabolism. It plays an important role in the process of * glucose metabolism. It has the effect of reducing body fat and improving lean meat percentage. Japanese scientists and technicians have proved that adding a certain amount of DHA * and pyruvate (calcium salt) mixture (according to the weight ratio of 3:1 *) can reduce the fat content of pig back meat, 12%~ 15%, the fat content of the leg muscle and the longest muscle of the back also decreases, and the protein content increases.

用于功能性食品

For functional foods

补充二羟基丙酮( 特别是和丙酮酸联用) 能够提高机体代谢率和脂肪酸氧化, 可潜在地有效燃烧脂肪而降低体脂和延缓体重获得( 减肥作用) , 并减少相关疾病的发病率, 也可以改善胰岛素敏感性和降低高胆固醇膳食所致的血浆胆固醇水平, 长期补充可使血糖利用率增加而节省肌糖元, 对运动员则可以提高有氧耐力成绩。

Dihydroxypyruvate supplementation (especially in combination with pyruvate) can increase metabolic rate and fatty acid oxidation, potentially effectively burn fat, reduce body fat, delay weight gain (weight loss), reduce the incidence of related diseases, improve insulin sensitivity and reduce plasma cholesterol caused by a high cholesterol diet. Alcohol level, long-term supplementation can increase the utilization rate of blood sugar and save muscle glycogen, for athletes can improve aerobic endurance performance.

其它用途

Other uses

二羟基丙酮还可直接作为一种抗病毒试剂, 如在鸡胚胎培养中, 使用DHA 能大大抑制鸡瘟病毒的感染, 杀死51% ~ 100% 的鸡瘟病毒。在制革工业中, DHA 可作为皮革制品的保护剂。另外, 以DHA 为主要成分的保鲜剂可用于果蔬、水产品、肉制品的防腐保鲜等。

Dihydroxyacetone can also be used as an antiviral agent directly, for example, in chicken embryo culture, DHA can greatly inhibit the infection of chicken plague virus, killing 51% to 100% of the virus. In leather making industry, DHA can be used as a protective agent for leather products. In addition, DHA as the main ingredient can be used for preservation of fruits and vegetables, aquatic products, meat products, etc.

间接用途

Indirect use

二羟基丙酮分子中含有3 个官能团( 2 个羟基、1 个羰基) , 化学性质活泼, 能广泛参与诸如聚合、缩合等反应, 是一种重要的医药、农药合成中间体。与脒、亚胺基醚类等物质反应, 可制得咪唑、呋喃等杂环化合物; 通过酯化反应可制得各种甘油三酯; 还可合成酮位取代化合物。其衍生物也是有机合成化学中一类非常重要的中间体, 用途极其广泛: 经生物或化学法还原可得到具有光学活性的仲醇; 用于羟醛缩合反应制取各种手性化合物; 直接用于光化学反应中的DielsAlder 加成反应制备糖类化合物; 与2,2-二烷氧基环丙烷衍生物作用制备内酯。此外, 以其衍生物为中间体合成的一些化合物, 还具有治疗心血管疾病、糖尿病和抗病毒活性( 如艾滋病) 的作用等

Dihydroxyacetone contains three functional groups (two hydroxyl groups and one carbonyl group). It is an important intermediate in the synthesis of medicine and pesticide because of its active chemical properties and wide participation in such reactions as polymerization and condensation. Heterocyclic compounds such as imidazole and furan can be prepared by reacting with amidine and imino ethers, and various triglycerides can be prepared by esterification, and ketone substituted compounds can also be synthesized. Its derivatives are also very important intermediates in organic synthesis chemistry, and they are widely used in many fields: optical secondary alcohols can be obtained by biological or chemical reduction; chiral compounds can be prepared by aldol condensation reaction; carbohydrates can be prepared by Diels Alder addition reaction in photochemical reaction; and 2,2-bis Alkoxy cyclopropane derivatives are used to prepare lactones. In addition, some compounds synthesized with their derivatives as intermediates have therapeutic effects on cardiovascular diseases, diabetes and antiviral activities (such as AIDS).
