Abstract
  1. The fatty acid composition of whole goldfish, whole-intestinal mucosa, intestinal mucosal membranes and individual phospholipids extracted from mucosal membranes were measured, fish adapted to different temperatures being used. 2. Alterations of the adaptation temperature did not noticeably affect the fatty acid composition of the whole-fish lipids, but there were marked changes in the fatty acids of lipids extracted from homogenates of goldfish intestinal mucosa. These changes were more pronounced in a membrane fraction prepared from these homogenates. Raising the adaptation temperature by 20 degrees C halved the percentage of C(20:1), C(20:4) and C(22:6) fatty acids and nearly doubled the percentage of C(18:0) and C(20:3) fatty acids recovered. 3. Choline phosphoglycerides constituted about one-half and ethanolamine phosphoglycerides about one-quarter of the total membrane phospholipids. 4. The fatty acids of choline and ethanolamine phosphoglycerides were more susceptible to temperature-dependent changes than were the phosphoglycerides of inositol or serine. 5. The increase in C(18:0) fatty acid that occurred in membranes of warm-adapted fish was greatest for ethanolamine phosphoglycerides, but increases also occurred in other phospholipid fractions and in membrane neutral lipids.
摘要
  1. 测定了不同温度适应条件下金鱼的全鱼、全肠黏膜、肠黏膜膜以及从黏膜膜中提取的单个磷脂的脂肪酸组成。2. 适应温度的改变对全鱼脂质的脂肪酸组成没有明显影响,但金鱼肠黏膜匀浆中提取的脂质的脂肪酸组成有显著变化。这些变化在由这些匀浆制备的膜组分中更为明显。将适应温度提高20摄氏度,C(20:1)、C(20:4)和C(22:6)脂肪酸的百分比减半,而回收的C(18:0)和C(20:3)脂肪酸的百分比几乎增加了一倍。3. 胆碱磷酸甘油酯约占膜磷脂总量的一半,乙醇胺磷酸甘油酯约占四分之一。4. 胆碱和乙醇胺磷酸甘油酯的脂肪酸比肌醇或丝氨酸的磷酸甘油酯更容易受到温度依赖性变化的影响。5. 适应温暖环境的鱼的膜中C(18:0)脂肪酸的增加在乙醇胺磷酸甘油酯中最为显著,但在其他磷脂组分和膜中性脂质中也有增加。
