维生素K(K2)的发现和功能

 
维生素K(K2)发现功能

维生素K, 又叫凝血维生, 是一类具有叶绿醌生物活性的萘醌基团的衍生物, 是人体中不可缺少的脂溶性维生素天然存在的有维生素K1K2维生素K1广泛存在于绿色植物中,是食物中维生素K的重要来源;维生素K2主要由肠道细菌合成。人工合成的有维生素K3K4K5K7等。在动物体内具有生物活性的是维生素K2,而维生素K1维生素K3都要转化为维生素K2才能起作用。三种维生素K的形式都在肝中转化成维生素K2,并和胃肠微生物合成的维生素K2一起被吸收利用
 
发现
 
丹麦科学家Henrik  Dam1929年在哥本哈根大学从事鸡的胆固醇代谢研究,当时一般认为,许多哺乳动物能在体内合成胆固醇,但设想鸡却缺乏这种能力。为了证实这种猜想,Dam用没有胆固醇, 却富有维生素AD的食物饲养鸡。他观察到鸡也能合成胆固醇,但更重要的发现是:如果继续用这种食物饲养2-3周,则鸡出现皮下、肌肉和其他器官的出血现象,而且鸡发生出血凝固得很慢;若在食物中加入脂肪、维生素C以及胆固醇,也对出血没有改善。因此,Dam认为,这是由于在食物中缺乏一种未知的元素所致。在寻找上诉食物中所缺少的元素过程中,发现绿色叶和猪肝是保护不犯出血病的最有效来源。Dam1935年把此因素称维生素K”,k德文中“Koagulation”(凝固)一词中的第一个字母.这个物质是脂溶性的,可从紫花苜蓿(alfalfa)中成功地分离出来.


绿色植物中分离出的维生素K被称K1,而由大肠腐败作用所产生的维生素K则称为K2,二者稍有不同,其差别首先由美国化学家Edward A.Doisv观察到,并于1939年将维生素K人工合成.  1943年,DamDoisv共同获得诺贝尔生理学或医学奖

      
功能

1、促进血液凝固
所以维生素K也称凝血维生素,   是凝血因子γ羧化酶的辅酶。而其它凝血因子7910的合成也依赖于维生素K 。人体缺少它,凝血时间长,严重者会流血不止,甚至死亡。对女性来说可减少生理期大量出血,还可防止内出血及痔疮。经常流鼻血的人,可以考虑多从食物中摄取维生素K

 

 

2、参与骨骼代谢。

 

 

 
维生素K2参与合成BGP (Bone Gla Protein) , BGP调节骨骼中磷酸的合成。别对老年人来说,他们的骨密度和维生素K呈正相关。经常摄入大量含维生素K绿色蔬菜的妇女能有效降低骨折的危险性。

 

3. 护心脏和血管

 

维生素K2可以激活MGP(Matrix Gla Protein),  MGP 是软骨内骨形成和血管内钙化的重要调节因子, 抑制血管钙化. 因此维生素K2可阻止钙沉积在血管壁上,防止心脏和血管疾病的发生

I really like the Nike Air Monarch ... fit and feel is great.
- Switzerland

Been getting these forever, love the fit, 13 4E. Perfect, comfortable.
- Singapore

Purchased them as a gift. They fit very comfortable and he's very happy with them.
- Liberia

Finally able to order my correct size without getting a size bigger to get the width I need.
- Singapore

Bought these for the hubby to replace the ones he wore out. He says they're the best he's found for his use.
- Singapore

Nike still makes a very high quality shoe. It offers excellent support and durability. This my second pair of this modal.
- Switzerland

Sneakers fit as advertised; it was in excellent condition; fit was comfortable, sturdy, and it works for casual use which is what I wanted.
- Switzerland

my husband bought these for himself and he loves them. he has bought these same shoes before in the past. he highly recommend these. good comfort and support.
- Switzerland

Husband has a wide foot with a high instep. This is the only shoe that fits him comfortably. Have purchased this shoe multiple times. Good price and well made. Will definitely purchase again.
- Singapore

I've seen a lot of reviews on these shoes, and a lot of complaints about the squeakiness of them, but they have yet to start squeaking on me after a week or so of wearing them. They fit, feel and look great, I would buy them again.

I usually wear headphones to listen to music when I go for a walk or go shopping, and I won't fall out in any posture while running or lying down.

2024-01-12 08:56:16--
It's very easy to use. The sound quality is very good. The battery life is also very long. It also supports voice. The appearance is small and cute, which is beyond my expectation.

2024-01-12 08:51:21--
Great beautiful sneakers

2024-01-12 08:51:14--
Wonderful comfortable shoes identical to the originals

2024-01-12 08:50:03--
not too bad, could have been leather as it said on the page

2024-01-12 08:48:44--
Shipping took 2 months but overall the trainers are good. Smell heavily of plastic.

2024-01-12 08:48:15--
Great shoe!!!

Shoes look great, Great quality!!! second time ordering from this vendor, shoes shipped fast and I love my items! thank you will definitely recommend this vendor!!!

2024-01-04 19:03:40--
For $40 can’t complain too much. Buy the Chloe writing starts in the middle of the strap and on the real ones and the photos advertising these it starts on they very edge of strap.

2024-01-04 19:03:21--
On time delivery. I love the quality! Also, it's comfortable. However, what i thought was light tan around the bottom portion of the sneakers is actually light pink. So if you don't like pink, pick another color. Great communication with the shoe company. Overall 👍🏾

2024-01-04 19:02:25--
Over the moon with the service and quality of these shoes. Look identical to the real ones, already wanting to order more!

2024-01-04 19:00:05--

2024-01-04 18:57:31--
I was sent the wrong shoes. I contacted seller. No answer. No response A 41 is like a 9.5/10 American size. I am a US 9. I usually order a 41 in Asian sizes. These run big. Bottom is red, but not the Christian Louboutin red. It’s cloudy and not as shiny as the real ones. It’s a cool shoe for a photoshoot. But not every day use. Make sure you go to your DHGATE account and open a refund return as soon as you get the item. This is not a good seller. Never respond. I never got my shoes I ordered. I would t recommend this seller.

2024-01-04 18:55:26--
Got the wrong color but good quality

2024-01-04 18:52:18--

2024-01-04 18:44:53--
Great experience the shoes were as described good quality only problem is if you have a wife feet you may need to go up a size bigger

2024-01-04 18:44:17--
This was my first ever order on DHgate so i was a little bit scared that i wouldn't get anything. Best shoes on DHgate, true to size. Fast shipping they arrived in 2 weeks in my country and stayed for 1 week at the customs. i also payed 22 euro for customduty but it wasworth the wait and price. Best shoes seller

Very good quality. Thanks

2024-01-03 23:56:32--
Very realistic looks real. Came in 3 weeks.

2024-01-03 23:53:01--
Looks real, but the smell is very strong definitely have to air it out or something. Got it in 19 days

2024-01-03 23:51:34--
I absolutely love the bag and color. I wish it was slightly bigger but it will still work. I’m so in love with the color 💙 Shipping time I can’t complain. Great quality material. Very authentic looking. Good purchase for the money

2024-01-03 23:49:33--
Smaller than expected

2024-01-03 23:48:28--
Literally looks nothing like the real bag. I’ve had other dupes before and my other one was 10000x better. Stitching is horrible, bag is HUGE, shape is off, and band is flimsy. Seller would not cooperate so I had to get DHgate involved for a refund. DO NOT BUY FROM THIS SELLER. good reviews are fake

2024-01-03 23:47:51--
Great item and price

2024-01-03 23:46:57--
Received…looks close to my Real one….chain is heavy… material feels slightly lighter / different but beautiful bag for the price. Logo is not stamped perfect but again it’s not bad for the price. Great bag and shipping was 2 weeks!

2024-01-03 23:46:11--
his bag is AMAZING!! If I could give it 100 stars, I would! I am 100% satisfied with my whole purchasing experience! I have many more photos I wish I could attach but they only allow 4. First start off with the seller: they have been so patient with me sending me all types of information from about the shipping to the actual product pictures. I have bought 2 Cha*** purses from this seller. Both of them are the exact same quality, from this seller. The quality control is fabulous. Second: the color of the purse is just beautiful! It’s such a beautiful soft peach. And the sheepskin is super buttery soft. I cannot stop feeling it! It feels so soft under my fingertips. Third: the shipping was super fast. It took 3 weeks to get to the US. I watched the tracking all away from beginning to end. Fourth: every detail is there. I cannot see one thing they missed when comparing two of my purses together. It came with the receipt, box, and dust bag. **this is a real review from the US**

2024-01-03 23:46:08--
I recommend this ring to everyone. The only flaw is the fact of choosing the size. In fact, choose at least one measure less than yours!

2024-01-03 23:45:47--
Very unsatisfied

2024-01-03 23:28:38--
I got the thin one and I think the infections in the carving could be a little deeper if that makes any sense. Also the bracelet itself is a little big so I had to put it up my arm to a thicker part so it wouldn’t dangle around my wrist. I do love it tho especially for the price !

2024-01-03 23:27:20--
nice and labeled.

2024-01-01 13:11:25--
Incredible quality!!! Can’t wait to buy more
