代谢
一些细菌使用甘油脱氢酶将甘油转化为二羟基丙酮(DHA)。随后,DHA通过依赖于ATP或磷酸烯醇丙酮酸(PEP)的DHA激酶被转化为DHA磷酸盐(DHA-P)。无害李斯特菌拥有两个潜在的PEP依赖性Dha激酶。其中之一是由甘油(gol)操纵子的11个基因中的3个编码的。这个操纵子还包含golD(lin0362),它编码一种新型的、依赖于NAD(+)的甘油脱氢酶,能形成DHA。DHA的后续代谢需要通过PEP:糖磷酸转移酶系统组件酶I、HPr和EIIA(DHA)-2(Lin0369)的磷酸化。P-EIIA(DHA)-2将其磷酸基团转移给DhaL-2,后者磷酸化与DhaK-2结合的DHA。产生的Dha-P可能主要通过戊糖磷酸途径代谢,因为gol操纵子的两个基因编码的蛋白质类似于转酮醇酶和转醛醇酶。此外,纯化的Lin0363和Lin0364分别表现出核糖-5-P异构酶(RipB)和三磷酸异构酶活性。后者将部分DHA-P转化为甘油醛-3-P,与DHA-P一起通过糖异生途径代谢形成果糖-6-P。与另一个甘油醛-3-P分子一起,转酮醇酶将果糖-6-P转化为戊糖磷酸途径的中间产物。gol操纵子之前是golR,以相反的方向转录,编码一个DeoR型阻遏蛋白。其失活导致整个gol操纵子,包括最后一个编码类植物素免疫蛋白(PedB-like)的基因的组成型表达,但这种表达会受到葡萄糖的抑制。在golR突变体中,其合成水平升高,与野生型菌株或PedB-like缺失突变体相比,对植物素PA-1的免疫力略有增加。
Several bacteria use glycerol dehydrogenase to transform glycerol into dihydroxyacetone (DHA). DHA is subsequently converted into DHA phosphate (DHA-P) by an ATP- or phosphoenolpyruvate (PEP)-dependent DHA kinase. Listeria innocua possesses two potential PEP-dependent Dha kinases. One is encoded by 3 of the 11 genes forming the glycerol (gol) operon. This operon also contains golD (lin0362), which codes for a new type of DHA-forming NAD(+)-dependent glycerol dehydrogenase. The subsequent metabolism of DHA requires its phosphorylation via the PEP:sugar phosphotransferase system components enzyme I, HPr, and EIIA(DHA)-2 (Lin0369). P-EIIA(DHA)-2 transfers its phosphoryl group to DhaL-2, which phosphorylates DHA bound to DhaK-2. The resulting Dha-P is probably metabolized mainly via the pentose phosphate pathway, because two genes of the gol operon encode proteins resembling transketolases and transaldolases. In addition, purified Lin0363 and Lin0364 exhibit ribose-5-P isomerase (RipB) and triosephosphate isomerase activities, respectively. The latter enzyme converts part of the DHA-P into glyceraldehyde-3-P, which, together with DHA-P, is metabolized via gluconeogenesis to form fructose-6-P. Together with another glyceraldehyde-3-P molecule, the transketolase transforms fructose-6-P into intermediates of the pentose phosphate pathway. The gol operon is preceded by golR, transcribed in the opposite orientation and encoding a DeoR-type repressor. Its inactivation causes the constitutive but glucose-repressible expression of the entire gol operon, including the last gene, encoding a pediocin immunity-like (PedB-like) protein. Its elevated level of synthesis in the golR mutant causes slightly increased immunity against pediocin PA-1 compared to the wild-type strain or a pedB-like deletion mutant.

二羟基丙酮和丙酮酸(DHP)的摄入增加了正常男性肌肉对葡萄糖的提取。为了检验这些三碳化合物是否能改善糖尿病患者的血糖控制,本研究评估了DHP对7名非胰岛素依赖型糖尿病女性患者的血浆葡萄糖浓度、转化率、回收率和耐受性的影响。受试者摄入1500卡路里的饮食(55%碳水化合物,30%脂肪,15%蛋白质),其中13%的热量随机来源于DHP(实验组;1/1)或Polycose(安慰剂;PL),每天三次,持续7天。在第8天,从早上05:00开始进行[6-(3)H]-葡萄糖和U-(14)C-葡萄糖的连续灌注,并在早上09:00进行3小时的葡萄糖耐量测试(75克葡萄糖)。两周后,受试者重复研究,使用另一种饮食。空腹血浆葡萄糖水平在DHP组下降了14%(DHP = 8.0 ± 0.9 mmol/L;PL = 9.3 ± 1.0 mmol/L,p < 0.05),这导致口服后血糖降低(DHP = 13.1 ± 0.8 mmol/L,PL = 14.7 ± 0.8 mmol/L,p < 0.05)。6-(3)H-葡萄糖的转化率(DHP = 1.50 ± 0.19 mg/kg-L/min,PL = 1.77 ± 0.21 mg/kg-L/min,p < 0.05)和葡萄糖回收率(6-(3)H-葡萄糖和U-(14)C-葡萄糖转化率的差异)在DHP组降低(DHP = 0.25 ± 0.07 mg/kg-L/min,PL = 0.54 ± 0.10 mg/kg-L/min,p < 0.05)。空腹和口服后的血糖、血浆胰岛素、胰高血糖素和C肽水平不受DHP影响。二羟基丙酮和丙酮酸的混合物。
... Consumption of dihydroxyacetone and pyruvate (DHP) increases muscle extraction of glucose in normal men. To test the hypothesis that these three-carbon compounds would improve glycemic control in diabetes the effect of DHP on plasma glucose concentration, turnover, recycling, and tolerance in 7 women with noninsulin-dependent diabetes /was evaluated/. The subjects consumed a 1,500-calorie diet (55% carbohydrate, 30% fat, 15% protein), randomly containing 13% of the calories as DHP (1/1) or Polycose (placebo; PL), as a drink three times daily for 7 days. On the 8th day, primed continuous infusions of [6-(3)H]-glucose and U-(14)C-glucose were begun at 05.00 hr, and at 09.00 hr a 3-hr glucose tolerance test (75 g glucola) was performed. Two weeks later the subjects repeated the study with the other diet. The fasting plasma glucose level decreased by 14% with DHP (DHP = 8.0 + or - 0.9 mmol/L; PL = 9.3 + or - 1.0 mmol/L, p less than 0.05) which accounted for lower postoral glucose glycemia (DHP = 13.1 + or - 0.8 mmol/L, PL = 14.7 + or - 0.8 mmol/L, p< 0.05). 6-(3)H-glucose turnover (DHP = 1.50 + or - 0.19 mg/kg-L/min, PL = 1.77 + or - 0.21 mmg/kg-L/min, p less than 0.05) and glucose recycling, the difference in 6-(3)H-glucose and U-(14)C-glucose turnover rates, decreased with DHP (DHP = 0.25 + or - 0.07 mg/kg-L/min, PL = 0.54 + or - 0.10 mg/kg-L/min, p< 0.05). Fasting and postoral glucose, plasma insulin, glucagon, and C peptide levels were unaffected by DHP. /Mixture of dihydroxyacetone and pyruvate/.

甘油醛(DHA)有效地拮抗了氰化物对小鼠和兔子的致死作用,特别是如果与硫代硫酸盐联合使用。口服DHA(2和4克/千克)在小鼠注射(腹腔注射)氰化物前10分钟给药,将氰化物的LD50值从5.7毫克/千克提高到12和17.6毫克/千克。如果口服DHA在注射氰化物前10-15分钟给药,DHA最有效地预防氰化物引起的死亡。口服DHA(4克/千克)预处理和注射氰化物后给予硫代硫酸钠(1克/千克)联合治疗,使氰化物的LD50提高了9.9倍。此外,给兔子在皮下注射氰化物后5分钟静脉注射DHA,将氰化物的LD50从6毫克/千克提高到超过11毫克/千克,而在氰化物注射后5分钟静脉注射硫代硫酸钠(1克/千克)仅将氰化物的LD50提高到8.5毫克/千克。DHA还预防了氰化物中毒后发生的抽搐。
Dihydroxyacetone (DHA) effectively antagonized the lethal effect of cyanide in mice and rabbits, particularly if administered in combination with thiosulfate. Oral DHA (2 and 4 g/kg) given to mice 10 min before injection (ip) of cyanide increased the LD50 values of cyanide from 5.7 mg/kg to 12 and 17.6 mg/kg, respectively. DHA prevented cyanide-induced lethality most effectively, if given orally 10-15 min before injection of cyanide. A combination of pretreatment with oral DHA (4 g/kg) and post-treatment with sodium thiosulfate (1 g/kg) increased the LD50 of cyanide by a factor of 9.9. Furthermore, DHA given intravenously to rabbits 5 min after subcutaneous injection of cyanide increased the LD50 of cyanide from 6 mg/kg to more than 11 mg/kg, while thiosulfate (1 g/kg) given intravenously 5 min after cyanide injection increased the LD50 of cyanide only to 8.5 mg/kg. DHA also prevented the convulsions that occurred after cyanide intoxication.

Cyanide-induced convulsions were also prevented by DHA treatment, either alone or in combination with thiosulfate. Injection (ip) of DHA (2 g/kg) 2 min after or 10 min before CN (sc) increased LD50 values of CN (8.7 mg/kg) by factors of 2.1 and 3.0, respectively.

制备方法与用途

概述

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。作为多功能添加剂,它广泛应用于化妆品、医药和食品行业。

二羟基丙酮

二羟基丙酮(Dihydroxyacetone, DHA)的化学名为1,3-二羟基-2-丙酮,是一种常用的化妆品成分,具有皮肤保湿、仿晒以及染发的功能。截至当前,DHA不属欧盟化妆品监管条例(Cosmetic Regulation (EC) No. 1223/2009)的监管范围。

2008年,欧盟消费者安全科学委员会(Scientific Committee on Consumer Safety, SCCS)收到一份企业提交的资料,用以支持DHA作为化妆品成分的安全性。研究数据表明,在化妆品中使用浓度不超过10%的DHA作为仿晒剂是安全的;此外,喷雾类化妆品中的DHA浓度若不超过14%,也是安全的。

2019年5月,SCCS再次收到申请,评估在驻留类(非氧化型)染发化妆品中使用浓度不超过6.25% DHA的安全性。根据企业提供的毒代动力学、皮肤刺激性和致敏性、急性毒性、生殖毒性、致突变及致癌等安全性评价数据,欧盟消费者安全科学委员会得出以下结论:在驻留类(非氧化型)染发化妆品中使用浓度不超过6.25%的DHA是安全的;与美黑乳液或浓度不超过10% DHA的面霜一同使用时亦被认为是安全的。

性状

二羟基丙酮为带有甜味的白色粉末状结晶。

应用 化妆品工业
  1. 作为防晒霜原料:二羟基丙酮主要用作化妆品配方中的原料,特别适用于防晒霜。它能防止皮肤水分过度蒸发,起到保湿、防晒和防紫外线辐射的作用。

  2. 模拟日晒肤色:DHA中的酮官能团可与皮肤角蛋白的氨基酸和氨基基团发生反应形成褐色聚合物,使皮肤产生类似长时间暴露于阳光下的自然棕色或棕褐色。因此,它可以作为日晒肤色的模拟剂。

提高猪的瘦肉率

二羟基丙酮是糖代谢过程中的中间产物,在糖代谢过程中起着重要作用,具有降低脂肪、提高瘦肉率的效果。

用途
  • 医药中间体:可合成治疗心血管疾病药物。
  • 化工原料和食品添加剂:应用于化妆品中,能阻止皮肤水分过度蒸发,对皮肤起到保湿和防晒作用,防止紫外线辐射。
