Abstract
Changes in fatty acid composition of phospholipids from human milk during the course of lactation were determined in milk from Korean lactating mothers giving birth at term. The levels of 8 : 0 increased significantly from colostral to transitional stages with a further small decrease at mature stage. The proportions of 10 : 0, 12 : 0 and 14 : 0 increased markedly from colostrum to transitional to mature milk. The w6-derived long-chain polyunsaturated fatty acids, 20 : 2w5, 20 : 4w6 and 22 : 4w5, were decreased with time of lactation. The levels of 24 : 1w9 were significantly higher in transitional milk than in colostrum and then significantly decreased to lowers than the colostral levels at mature milk.
한국인 중류층 수유부들로부터 분만 후 70일까지 채취한 유즙의 인 지방질의 자방산 조성이 수유기간의 경과에 어떻게 변화하는지 살펴보았다. 8 : 0 은 이행유 단계에서, 그리고 10 : 0, 12 : 0, 14 : 0 등은 성숙유 I단계에서 각각 유의하게 증가하였다. w6계 대사산물들(20 :2w6, 20 : 4w6, 22 : 4w6)은 수유기간의 경과에 따라 점진적인 감소의 경향을 나타내었다. 24 : 1w9는 이행유 단계에서 유의한 증가의 수준을 유지하다가 그 이후는 초유 수준 이하로 유의하게 감소하였다.
