Bî-tá-mín K

微打 (Bî-tá)mín K是 (sī)由 (iû)bî-tá-mín K1 (phylloquinone)， K2 (menaquinone)，佮 (kap)K3 (menadione) 所 (só͘)組成 (cho͘-sêng)的 (ê)一 (chi̍t)組 (cho͘)bî-tá-mín。 K1藏 (chhàng)佇 (tī)青色 (chheⁿ-sek)的葉仔 (hio̍h-á)呢 (nih)， K2會使 (ē-sái)遊 (iû)動物 (tōng-bu̍t)長阿 (tn̂g-á)內 (lāi)的細菌 (sè-khún)合成 (ha̍p-sêng)，猶 (ah)K3是人工 (jîn-kang)合成的。微打mín K賢 (gâu)予 (hō͘)酸 (sng)，鹼 (kiⁿ)，佮氧化劑 (ióng-hoà-che)來 (lâi)破害 (phò-hāi)，對 (tùi)光 (kng)無 (bô)穩定 (ún-tēng)，上好 (siāng-hó)愛 (ài)保存 (pó-chûn)佇暗色 (àm-sek)的奸仔呢 (kan-á--nih)。微打mín K會使封層 (pang-chàn)人體 (jîn-thé)合成濟濟 (chē-chē)重要 (tiōng-iàu)的激血 (kek-hoeh)因子 (in-chú)，若準 (nā-chún)有 (ū)欠 (khiàm)就會 (tio̍h-ē)造成 (chō-chiâⁿ)激血功能 (kong-lêng)的各樣 (koh-iūⁿ)。

Figure 1: Chemical structures of vitamin K1 (phylloquinone， left structure) and vitamin K2 (menaquinones， right structure)。 Both contain a functional naphthoquinone ring and an aliphatic side chain。 Phylloquinone has a phytyl side chain， whereas in menaquinone the side chain is composed of a varying number of isoprenoid residues.
