科普專欄–薯不揀單 - 深入淺出–關於精子尾部的研究

精子與卵子的融合，象徵著一個新生命的誕生。642Please respect copyright.ＰＥＮＡＮＡ2lz7sUbEqQ

（圖2）近來陸續有研究發現，精子的尾部有著名為Glycylation的結構，由至少三個名為Glycine的氨基酸組成。642Please respect copyright.ＰＥＮＡＮＡQtFdbB3evz

（圖3）尾部擁有Glycylation結構的精子，接近9成時間都會直行。642Please respect copyright.ＰＥＮＡＮＡAlGONtDL5k
而缺乏該結構的精子，則有接近8成的時間會原地打轉。642Please respect copyright.ＰＥＮＡＮＡQZCfGBkSHz

（圖4）大概是高機率原地轉圈的關係，尾部缺乏Glycylation結構的精子，與卵子結合的機率將會大減。642Please respect copyright.ＰＥＮＡＮＡfOAPdeqzKG

尾部缺乏Glycylation結構的精子，其蛋白質Dynein的內部組成結構亦有所不同。642Please respect copyright.ＰＥＮＡＮＡwisai3wEni
這亦相信是導致精子原地轉圈的主要原因之一。642Please respect copyright.ＰＥＮＡＮＡXtiX7SYUrH

如何讓男士們的精子尾部結構保持合適數量的Glycylation結構，將有可能是解決不育的其中一道手段。642Please respect copyright.ＰＥＮＡＮＡNLOZ4F6lT5
