維生素d35ug相當於多少國際單位

1. d35ug等於多少單位

這里的35ug
實際上指的是μg，即35微克
微克是很小的質量單位
1毫克=1000微克，1克=1000毫克
即1克=1000000即10的6次方微克
所以35μg為0.035毫克，或者3.5*10^-5 克

2. 2.5ug維生素d3是多少國際單位

維生素D3：1ug=40IU

國際標准：1IU維生素D=0.025ug維生素D3

有些葯物如維生素、激素、抗生素、抗毒素類生物製品等，它們的化學成分不恆定或至今還不能用理化方法檢定其質量規格，往往採用生物實驗方法並與標准品加以比較來檢定其效價。

通過這種生物檢定，具有一定生物效能的最小效價單元就叫」單位」（u）；經由國際協商規定出的標准單位，稱為」國際單位」（IU）。國際標准品主要是供給各國來建立和標化自己的國家標准品。對於還沒有建立國際標准品的葯物可以由本國制訂國家標准品。

單位換算

微克為質量單位，質量單位的國際單位為kg，2.5微克(μg)=2.5000e-9千克(kg)。

國際單位制中的質量單位是千克（kg）。

千分之一公斤嚴格定義為18×14074481個C－12原子的重量。

常用的質量單位為：噸（t），克（g），毫克（mg），微克（μg）。

換算關系：1t=1000kg；1公斤=1000克；1克=1x10^3毫克=1x10^6微克。

3. 3ug是多少國際單位

3ug是120個國際單位。3ug等於3ng。1ng/mL=1ug/L， 因為1ng=0.001ug;，1mL=0.001L所以1ng/mL=0.001ug/0.001L=1ug/L。

維生素D換算是0.025ug=1個國際單位，也就是1ug=40個國際單位。3ug=120個國際單位。

國際單位制

源自公制或米制，舊稱萬國公制，是現時世界上最普遍採用的標準度量衡單位系統，採用十進制進位系統。

是18世紀末科學家的努力，最早於法國大革命時期的1799年被法國作為度量衡單位。

國際單位制是在公制基礎上發展起來的單位制，於1960年第十一屆國際計量大會通過，推薦各國採用，其國際簡稱為SI。

4. 4000毫克d3是多少單位

40國際單位。d3是微克的維生素是國際單位。4000毫克d3是微克的維生素D3有40國際單位。維生素D31微克=40單位國際標准為1IU維生素D=0.025ug維生素D32.8*40=112單位，維生素D3一般每日需要量是400單位。不要過量補充。

5. 50ug/d什麼意思

其實就是含葯量。不同的葯品換算不一樣，如1微克的維生素D相當於40國際單位，所以5.5ug的維生素d是220國際單位。
一個」單位」或一個」國際單位」可以有其相應的重量，但有時也較難確定。單位與重量的換算在不同的葯物是各不相同的。
1931年國際聯盟衛生組織的維生素委員會，首先規定了各種維生素的國際單位；如每1個國際單位的維生素A相當於0.3微克，若是它的乙酸鹽則為0.344微克，維生素D相當於0.025微克，維生素E相當於1毫克等等。雖然許多維生素現今已改為重量表示，但維生素A和D仍然沿用國際單位。
各種激素1國際單位摺合國際標准制劑的重量為：黃體酮1毫克、絨毛膜促性腺素0.1毫克、垂體激素0.5毫克、催乳激素0.1毫克、胰島素45.4微克。

6. 維生素當量及單位換算

一個國際單位相當於0.025微克的維生素D3，一微克的維生素D3有40國際單位.所以7.5微克的維生素d相當於300單位的維生素d。 1ug等於40單位的維生素d，7.5ug應該相當於300單位。我們每天維生素d的生理需要量，至少應該在400到600單位。

Vitamin A Technical Details:

Vitamin A is a fat-soluble vitamin. It is important for vision, bone growth and cell division.

Vitamin A consists of Retinol from animal sources, and Provitamin A Carotenoids from plant sources.

Retinol is referred to as pre-formed vitamin A. This means that it can be used directly by the body.

Provitamin A Carotenoids are Vitamin A precursors . This means that they are converted to Vitamin A by the body. However, conversion of the carotenoids is less efficient than that of retinol.

The Provitamin A Carotenoids are beta-carotene, alpha-carotene, beta-cryptoxanthin, lycopein, lutein and zeaxanthin (lutein and zeaxanthin are combined in the current database). The carotenoids are responsible for the red and yellow pigments of plants.

A unit called Retinol Activity Equivalents (RAE) is used to compare the Vitamin A activity of the different forms of Vitamin A. 1 µg (microgram) of retinol is equivalent to 1 µg RAE. However it takes 12 µg beta-carotene to equal 1 µg RAE, and 24 µg of the other carotenoids to equal 1 µg RAE. The following table summarizes the conversion of vitamin A values to RAE:

Historical Measures of Vitamin A

Previously, a unit called International Units (IU) was used to describe Vitamin A activity. However, at the time International Units for Vitamin A were defined (1989), it was thought that beta-carotene was half as concentrated as retinol (beta-carotene is now considered to be only 1/12 as concentrated as retinol).

Because of this, Vitamin A measurements expressed as IU tend to over-state the contribution of the provitamin A carotenoids. The following table summarizes the conversion of Vitamin A values to IU:

When it was determined that IU tended to overstate the contribution of the provitamin A carotenoids, a new unit called Retinol Equivalents (RE) was defined to describe the new values. At the time beta-carotene was thought to be 1/6 as concentrated as retinol. The following table describes the conversion of vitamin A values to RE:

In 2001, the National Academy of Sciences Institute of Medicine (NAS IOM) determined that Vitamin A activity from carotenoids is only half of what was previously believed. To account for this difference, and to avoid confusion, the new unit Retinol Activity Equivalents (RAE) was defined. Retinol Equivalents (RE) are no longer used.

The following table summarizes the relationship between the different measures:

IU Details

At the time of this writing (2004), the RDI (Reference Daily Intake) of Vitamin A is 5000 IU. However, IU is an inaccurate measure of vitamin A activity because it overstates the contributions of the provitamin A carotenoids (by a factor of 6). The FDA (US Food and Drug Administration) is considering changing the RDI to express it in terms of RAE.

Because the conversion of IU to RAE is different for retinol and the carotenoids, you cannot convert IU to RAE (or RAE to IU) for Total Vitamin A unless you know the proportion of retinol to carotenoids in the sample.

For example, knowing that you have 40 IU of Total Vitamin A is not enough information to determine how much retinol and carotenoids you have. 40 IU of Total Vitamin A can come from 12 µg RAE of retinol, or from 2 µg RAE of carotenoids, or from 6 µg RAE retinol plus 1 µg RAE carotenoids, or from many other combinations of retinol and carotenoids. The following table summarizes:

nutraCoster Details

Entering Retinol or Carotenoids Values

When you enter RAE for retinol or any of the carotenoids, nutraCoster automatically calculates the IU and %RDI values for the nutrient.

Finally, nutraCoster willrecalculate the IU and %RDI values of Total Vitamin A based on the new values for retinol and carotenoids.

Example: Suppose you have 80 µg RAE Total Vitamin A, which is composed of 60 µg RAE retinol and 20 µg RAE total carotenoids. The following table lists the values for the example:

Now change the Total Vitamin A RAE to 120 µg RAE. nutraCoster performs the following steps:

Total Vitamin A RAE was the sum of the retinol and carotenoids values, so nutraCoster increases retinol and carotenoids proportionally to 90µg RAE and 30 µg RAE.

The new value of 90 µg RAE for retinol converts to 300 IU and 6 %RDI.

The new value of 30 µg RAE for carotenoids converts to 600 IU and 12 %RDI.

Using the new IU and %RDI values, Total Vitamin A is now 900 IU and 18 %RDI.

The following table shows the results after the change:

nutraCoster performs a similar series of steps when you enter IU or %RDI values for Total Vitamin A.

CarotenoidDetails

When you enter or change a value for Total Carotenoids, nutraCoster checks to see if the Total Carotenoids value was equal to the sum of the indivial Provitamin A Carotenoids before the change. If it was, nutraCoster recalculates the indivial carotenoid values so the sum of the values equals the new Total Carotenoids value, while keeping the proportions the same.

When you enter or change a value for any of the indivial carotenoids, nutraCoster checks to see if the Total Carotenoids value was equal to the sum of the indivial Provitamin A Carotenoids before the change. If so, nutraCoster adjusts the Total Carotenoids value to equal the sum of the indivial carotenoid values after the change.

為了統一計量膳食中的維生素A，而提出的一個概念。其含義是包括視黃醇和β-胡蘿卜素在內的具有維生素A活性物質所相當的視黃醇量。

由於人體 維生素A 來源於動物性食物的維生素A和植物性食物中的 胡蘿卜素 （ 維生素A原 ），而維生素A的常用計量單位為國際單位（IU），胡蘿卜素的常用計量單位為μg（微克）或者mg（毫克），為了統一計量膳食中的維生素A， FAO /WHO（1967）提出了視黃醇當量（Retinol Equivalent, RE)概念。其含義是包括視黃醇和 β-胡蘿卜素 在內的具有維生素A活性物質所相當的視黃醇量。

視黃醇當量、 維生素A 、 β-胡蘿卜素 的換算關系如下：

1μg β-胡蘿卜素=0.167μg視黃醇當量（理論上1分子β-胡蘿卜素能形成2分子維生素A，但因為 胡蘿卜素 的吸收率為1/3，而吸收後轉化為維生素A的 轉化率 又只有1/2，所以，1μg的胡蘿卜素只能折算為0.556IU維生素A，即0.167μg視黃醇當量。1IU維生素A=0.3μg視黃醇當量）

7. 5ug=多少單位

5ug是5微克。

換算：

1000 納克（ng）=1μg

1000 微克（μg）=1㎎（毫克）

1000毫克（㎎）=1g

1000 克=1㎏
