簡介

肉堿 (carnitine),或音譯卡尼丁,是一種類氨基酸,屬于季銨陽離子復(fù)合物,可以透過生物合成方法從賴氨酸及蛋氨酸兩種氨基酸合成產(chǎn)生。肉堿存在有兩個(gè)立體異構(gòu):包括有生物活躍的L-肉堿,以及其非生物活躍的對(duì)映異構(gòu)體D-肉堿。以化學(xué)方式合成,同時(shí)存在L和D兩種肉堿的化合物,則一般以“DL-肉堿”的形式標(biāo)示。在中國大陸,L-肉堿有一個(gè)更常見的商品名稱:左式肉堿或左旋肉堿。 左式肉堿最初是以黃粉蟲的生長因子而被發(fā)現(xiàn),當(dāng)時(shí)曾被命名為“維生素Bt”。在生物的細(xì)胞里,當(dāng)脂肪新陳代謝產(chǎn)生能量時(shí),左式肉堿是把脂肪酸從胞質(zhì)溶膠運(yùn)送到線粒體內(nèi)所必需的,以防止脂肪酸積聚在細(xì)胞內(nèi)。在世界各地,左式肉堿經(jīng)常都被包裝成為營養(yǎng)補(bǔ)充劑而售賣,并聲稱能夠幫助燃燒脂肪,幫助減肥。
