火焰的味道

[-]
我们都知道吃辣椒能让你的舌头火上一把并且大汗淋漓,但是之前研究人员一直认为这只是化学元素对神经的刺激,并没有产生真正的热量。但是,丹麦的奥尔胡斯大学的Yasser Ahmed Mahmmoud研究发现——辣椒确实可以产生热量,这一发现的未来产生巨大作用。

事实上,辣椒的辛辣成分——辣椒素(CPS),能对一种叫SERCA的肌肉蛋白产生影响。通常情况下,SERCA 消耗 ATP(一种分子燃料)将钙离子"泵"过细胞膜(上的钙离子通道),这有助于收缩了的肌肉舒张放松。但是辣椒素的增加会关闭钙离子通道,导致 SERCA 消耗的 ATP 只能以热量的形式释放,这就是所谓的生热作用。当这一“作用”同时在数千(我估计绝对不是千这个数量级)个地方发生的时候,你就"生产"了可观的热量。【非常感谢 Kirdon 和 shawn 的指正!】

这可以解释为什么辣椒素和红辣椒有助于增强新陈代谢,并能提高体温——过去,辣椒作为人们提高体温,回暖和取暖的重要工具。这是第一次研究人员发现了一种有助于提升提问的化合物,有人相信这对于治疗体温过低会很有效。那个时候,如果你冷得发抖,或许可以来一茶匙辣酱而不是毛毯。

    ATP是生物体内储存能量的最主要物质,ATP被水解为ADP,高能磷酸键被剪断,由此放出能量

    鄙人对第二段的翻译,请指教:
    事实上,辣椒的辛辣成分——辣椒素(CPS),能对一种叫SERCA的肌肉蛋白产生影响。通常情况下,SERCA 消耗 ATP(一种分子燃料)来刺激钙离子泵过细胞膜,这有助于收缩了的肌肉舒张放松。但是辣椒素的增加会关闭钙离子泵,导致本应由SERCA 消耗的 ATP却以热量的形式被释放,这就是所谓的生热过程。(但人体是个庞大的系统,生热过程不止一个)一个“过程”产生的热以数千为因子相乘,你就会感觉到在生产着可观的热量。

    在雪夜里可不要用辣椒代替毛毯和食物,
    他只是刺激能量释放,而自己并没有供给能量。
    辣椒、酒精提高体温的代价可是大大消耗体内能量储备

    。。。。感觉辣 是喝凉水还是热水啊?

    那应该不是”钙的泵”,而是”钙离子通道”吧?

    @summer.Mars: 喝牛奶,比较解辣.

  12. 161135

    我在Kirdon的基础上改了改。。。

    事实上,辣椒的辛辣成分——辣椒素(CPS),能对一种叫SERCA的肌肉蛋白产生影响。通常情况下,SERCA 消耗 ATP(一种分子燃料)将钙离子”泵”过细胞膜(上的钙离子通道),这有助于收缩了的肌肉舒张放松。但是辣椒素的增加会关闭钙离子通道,导致 SERCA 消耗的 ATP 只能以热量的形式释放,这就是所谓的生热作用。当这一“作用”同时在数千(我估计绝对不是千这个数量级)个地方发生的时候,你就”生产”了可观的热量。

  13. 161137

    @summer.Mars: 热水比较快。冷水一时痛快,但是之后还是辣。热水喝的时候痛苦,不过喝了就好多了。

    @小斌斌@BT: 厄……似乎是的。不过竞赛中两者都有提到。
    另外再修正一下翻译:
    “来刺激钙离子泵过细胞膜”——“来刺激钙离子主动运输穿过细胞膜”

    One other issue issue is that video games are usually serious in nature with the principal focus on knowing things rather than leisure. Although, it has an entertainment element to keep children engaged, every single game is generally designed to work with a specific expertise or area, such as mathematics or research.

    I acquired more a new challenge on this fat loss issue. Just one issue is a good nutrition is extremely vital any time dieting. A massive reduction in fast foods, sugary ingredients, fried foods, sweet foods, red meat, and white flour products could be necessary. Holding wastes parasites, and wastes may prevent targets for losing belly fat. While a number of drugs briefly solve the challenge, the awful side effects are not worth it, and in addition they never offer more than a short-term solution. It is just a known indisputable fact that 95% of celebrity diets fail. Many thanks for sharing your opinions on this weblog.

    Thanks for the several tips shared on this site. I have seen that many insurance firms offer clients generous discounts if they favor to insure more and more cars together. A significant amount of households possess several motor vehicles these days, specially those with more aged teenage young children still dwelling at home, and also the savings with policies can certainly soon mount up. So it makes sense to look for a great deal.

    Apple now has Rhapsody as an app, which is a great start, but it is currently hampered by the inability to store locally on your iPod, and has a dismal 64kbps bit rate. If this changes, then it will somewhat negate this advantage for the Zune, but the 10 songs per month will still be a big plus in Zune Pass’ favor.

  45. 928681

    Thanks for the suggestions you have shared here. Furthermore, I believe there are numerous factors that will keep your motor insurance premium decrease. One is, to take into account buying motors that are from the good set of car insurance businesses. Cars which are expensive tend to be at risk of being lost. Aside from that insurance policies are also based on the value of the car, so the higher in price it is, then the higher a premium you spend.
