丙酮酸钙物理化学性质

外观: 淡黄色至白色粉末
丙酮酸钙是丙酮酸的钙盐,很稳定,白色结晶粉末,无味,近乎中性,微溶于水。丙酮酸却极不稳定,极易被氧化,弱氧化剂Fe与H2O2能把丙酮酸氧化成乙酸并放出二氧化碳。丙酮酸是有机体内糖类代谢过程中的中间产物,也是蛋白质类与脂类代谢必经的中转站,它在自然条件下为无色有刺激性气味的液体,沸点165℃(分解),易溶于水,除了具有羟酸与酮的典型性质外,还具有a-酮酸的特性,丙酮酸是最简单的a-酮酸(属于羟基酸)。 

丙酮酸钙产品作用

用作医药的原料和食品添加剂。
丙酮酸钙是丙酮酸的钙盐。丙酮酸钙作为膳食补充剂,具有加速脂肪消耗、减轻体重、增强人体耐力、提高竞技成绩等功效;对心脏有特殊的保护作用,可增强心脏肌肉的效能,减少心脏病或心脏局部缺血造成的损伤;同时,丙酮酸钙具有吞噬体内自由基和抑制自由基的生成等显著效果。 
减肥清脂
丙酮酸钙进入机体内首先被胃分泌的盐酸置换为弱性有机酸-丙酮酸(分子量为88),极易透过细胞膜而进入细胞内,通过渗透作用到达机体细胞的能量加工厂-线粒体,将运进来的脂肪酸(主要是长链型)氧化燃烧供能,机体宏观表现为脂肪减少、体重减轻。美国匹兹堡大学医学研究中心的科学试验结果让人惊讶:丙酮酸钙可以增加至少48%的脂肪消耗。
该机构的研究人员让受试者日常补充丙酮酸钙的同时摄影入高脂食物,血浆中的胆固醇和低密度脂蛋白(LDL),分别降低4%和5%,而那些只食高脂食物不食丙酮酸钙受试者的胆固醇保持不变;在接受六周的丙酮酸钙摄食后,测其心率、血压、心率/血压,分别降低9%、6% 、12%。美国匹兹堡大学医学研究中心的医学博士罗纳尔·斯坦克说,它就是通过这种参与脂肪氧化来操纵脂肪代谢的。因而,丙酮酸钙在减肥消脂方面功效显著目前国内已有两种保健食品面世了。

丙酮酸

丙酮酸是人体的一种成分,在人体内主要参与糖、脂肪等的代谢,也是碳水化合物代谢的中间产物之一。

丙酮酸及它生成的盐,在医药领域应用很广,用于生产镇静剂、抗氧剂、抗病毒剂、合成治疗高血压的药物等等。

丙酮酸又称乙酰甲酸、 焦性葡萄酸、2-氧代丙酸。浅黄色至黄色的透明液体。有醋酸气味。有酸味。天然品存在于薄荷及蔗糖发酵液中。相对分子质量88.06。相对密度 1.2271。熔点13.8℃。沸点165℃(分解)、 106.5℃(13.332×103Pa)、85.3℃(5.333×103 Pa)、70.8℃(2.666×103Pa)、57.9℃(1.333×103 Pa)、45.8℃(0.667×103Pa)、21.4℃(0.133×103 Pa)。闪点82℃。折射率1.4280。与水、乙醇、乙醚等混溶。在空气中颜色变暗。加热时缓慢聚合,富有反应性,容易与氮化物、醛、卤化物、磷化物等反应,参与生物体的糖代谢、胶质、氨基酸、蛋白质等的生化合成、代谢、醇的发酵等。当用力时,在肌肉中被还原为乳酸,休息时再次氧化并部分转变为糖原。大鼠经口LD502100mg/kg。


用途

用于医药、氨基酸(L-酪氨酸的底物)等的合成,可提高效率,特别是在制药工业方面可缩短流程,简化流程,例如用本品制成的2-苯基辛可宁酸,是一种解热镇痛、利尿药,采用本品为原料,可大大降低生产成本;此外还用作抗结核药、异菸肼丙酮酸钙、激素的合成,驱虫剂扑绕灵(Pyrunium pamote)的原料;也用于农药原料;以丙酮酸、吲哚和氨为原料,进行生化反应,可制造色氨酸;生产味精,为提高L-苏氨酸的产率,可采用本品;香料,是我国GB2760—1996规定允许使用的食用香料。


制法

1,以乳酸酯为原料进行气相或液相氧化制得丙酮酯,进一步水解可制得。

2,以酒石酸为原料,在其中加入硫酸氢钾和硫酸氢钠,加热至210~220℃,脱氢,可得丙酮酸粗品,再利用减压精馏精制。

3,以2,2-二氯丙酸为原料,采用氢氧化钠,调节pH=6左右,进行水解,可制得。

丙酮酸的钙盐

丙酮酸钙是丙酮酸的钙盐,很稳定,白色结晶粉末,无味,近乎中性,微溶于水。丙酮酸却极不稳定,极易被氧化,弱氧化剂Fe与H2O2能把丙酮酸氧化成乙酸并放出二氧化碳。丙酮酸是有机体内糖类代谢过程中的中间产物,也是蛋白质类与脂类代谢必经的中转站,它在自然条件下为无色有刺激性气味的液体,沸点165℃(分解),易溶于水,除了具有羟酸与酮的典型性质外,还具有a-酮酸的特性,丙酮酸是最简单的a-酮酸(属于羟基酸)。

丙酮酸钙目前在我国还只能够进行化学合成,生产出来的都是工业原料级别的丙酮酸钙,这样得到的丙酮酸钙是消旋体(就是左旋丙酮酸钙和右旋右旋丙酮酸钙的一样多),而人体中只有左旋结构的丙酮酸能被人体吸收。目前我国在医药、减肥方面所使用的丙酮酸类产品,绝大部分需要从国外进口。日本在这方面的生产技术处于国际领先地位,能够通过生物发酵的方法生产出左旋结构的丙酮酸产品。

用作医药的原料和食品添加剂。丙酮酸钙作为膳食补充剂,具有加速脂肪消耗、减轻体重、增强人体耐力、提高竞技成绩等功效;对心脏有特殊的保护作用,可增强心脏肌肉的效能,减少心脏病或心脏局部缺血造成的损伤;同时,丙酮酸钙具有吞噬体内自由基和抑制自由基的生成等显著效果。

丙酮酸钙也是钙营养补充剂。虽然其含钙量不足20%,但进入人体内不像其他补钙产品酸根离子会增加肝肾负担,产生副影响,丙酮酸根离子可以进入细胞参与有机物代谢既减肥又不影响蛋白质的贮存。


减肥清脂

  丙酮酸钙进入机体内首先被胃分泌的盐酸置换为弱性有机酸-丙酮酸(分子量为88),极易透过细胞膜而进入细胞内,通过渗透作用到达机体细胞的能量加工厂-线粒体,将运进来的脂肪酸(主要是长链型)氧化燃烧供能,机体宏观表现为脂肪减少、体重减轻。美国匹兹堡大学医学研究中心的科学试验结果让人惊讶;丙酮酸钙可以增加至少48%的脂肪消耗。该机构的研究人员让受试者日常补充丙酮酸钙的同时摄影入高脂食物,血浆中的胆固醇和低密度脂蛋白(LDL),分别降低4%和5%,而那些只食高脂食物不食丙酮酸钙受试者的胆固醇保持不变;在接受六周的丙酮酸钙摄食后,测其心率、血压、心率/血压,分别降低9%、6% 、 12%。美国匹兹堡大学医学研究中心的医学博士罗纳尔·斯坦克说,它就是通过这种参与脂肪氧化来操纵脂肪代谢的。因而,丙酮酸钙在减肥消脂方面功效显著目前国内已有两种保健食品面世了。

 

丙酮酸钙应用领域

增加耐力:美国匹兹堡大学医学研究中心的罗纳尔·斯坦克博士首先让志愿者在接受试验之前进行运动耐力测试,之后让他们连续七天服用丙酮酸钙结果表明丙酮酸钙增辑受试者至少20%的耐力。这对运动员来说有无比重要的意义,会给体力劳动者、高强度脑力劳动者及运动员带来巨大的生命活力,但其性质不属于兴奋剂,所以它的开有无量的前途。
极好的钙营养补充剂:丙酮酸钙也是钙营养补充剂。虽然其含钙量不足20%,但进入人体内不像其他补钙产品酸根离子会增加肝肾负担,产生副影响,丙酮酸根离子可以进入细胞参与有机物代谢既减肥又不影响蛋白质的贮存。
降低胆固醇与低密度胆固醇(LDL):这在临床营养学上有重要意义,有效预防高血指及相关病症的出现,因为造成心脑血管动脉粥样硬化的主要成分是低密度胆固醇(LDL)。
改善心脏功能:这主要是丙酮酸钙作用于心肌细胞线粒体,及时供给心肌活动所需能量,提高心肌泵血耐力,从而能延长心脏寿命。
