母乳除含有對付病毒細菌的抗體外,亦含有不同款式的糖類化合物,統稱為Human Milk Oligosaccharides(HMO)。1034Please respect copyright.PENANAFU2n1Kgg8R

這些HMO無法被人體消化,故此接近有90%的HMO均能在嬰兒的便便中尋覓得到。1034Please respect copyright.PENANARsXMxTJbCQ

(圖2)細菌病毒大多需要透過腸道細胞表面的蛋白質入侵身體,然而這些HMO的結構與那些蛋白質的形狀非常相似,因此能夠阻擋細菌病毒透過腸道表面蛋白質進入身體。1034Please respect copyright.PENANA52AGOiVHB3

諾如病毒(Noroviruses)是導致嬰兒肚痾的主要元兇,若母乳某類的HMO含量(lacto-N-difucohexaose)較高的話,嬰兒因此病毒導致肚痾的機率亦會較低。1034Please respect copyright.PENANAYHZnxa56Yl

(圖3)除HMO外,母乳亦含有大量名為乳鐵蛋白(Lactoferrin)的蛋白質。1034Please respect copyright.PENANAhAftn9l0GZ

它具有吸取細菌所需的鐵質能力,因此能抑制細菌的生長;1034Please respect copyright.PENANAUBHPOyZpHE
它亦能破壞某類細菌的細菌壁,直接將細菌擊倒。1034Please respect copyright.PENANAgaOXLu9Gu8

在兔仔及老鼠的動物模型實驗中,乳鐵蛋白對抗細菌的能力亦得以證實。1034Please respect copyright.PENANAgfuwPHUO4f
有研究嘗試為嬰兒產品加入乳鐵蛋白成份,亦錄得嬰兒肚痾次數或脫水機率得以降低。1034Please respect copyright.PENANAf51fsm5MDQ
