Abstract

1.
1. The fatty acid composition of triglycerides and phospholipids isolated from the lungs, adipose tissue, intestine and liver was determined in newborn rats, in rats aged 1, 10 and 30 days, and in adult animals.
2.
2. Only the myristic and lauric acid contents of the triglycerides were found to change with changes in their content in the diet (milk against the solid diet for adult animals). Marked changes occurred in the fatty acid composition of the triglycerides during development in the different organs but these could not always be related to changes in the composition of the diet.
3.
3. The composition of fatty acids in the phospholipids differed with age and between organs. The lungs had the most specialized phospholipids, containing the aldehydes of stearic and palmitic acids and differing from the other organs also in their content of the other acids. Changes in the fatty acid composition of the diet were not reflected in the fatty acid composition of the phospholipids, although pronounced developmental changes were observed.

发育大鼠脂肪酸组成

1.1. 测定了新生大鼠、1日龄大鼠、10日龄大鼠、30日龄大鼠和成年动物肺、脂肪组织、肠和肝脏中分离的甘油三酯和磷脂的脂肪酸组成。只有甘油三酯的肉豆蔻酸和月桂酸含量随其在日粮中含量的变化而变化(成年动物的牛奶与固体日粮)。在不同器官的发育过程中，甘油三酯的脂肪酸组成发生了显著的变化，但这些变化并不总是与饮食组成的变化有关。磷脂中脂肪酸的组成随年龄和器官的不同而不同。肺有最特化的磷脂，含有硬脂酸和棕榈酸的醛，在其他酸的含量上也与其他器官不同。饲料中脂肪酸组成的变化没有反映在磷脂的脂肪酸组成上，尽管在发育过程中观察到明显的变化。
