Algae from cold water (Canada) and warm water (China) were analyzed for their total lipid content, and for their fatty acid (FA) composition and content. The major findings are that FA from Canadian algae are generally richer in polyunsaturated FA (PUFA), with a higher n-3/n-6 FA ratio, and a higher degree of total unsaturation. The 18 C, 4 double bonds FA (18 : 4 stearidonic acid, morotic acid as synonym) was detected in greater amounts in cold water samples. The high levels of total PUFA, and especially of n-3 FA in Canadian algae, suggests their possible utilizations for nutritional purposes.
对来自冷水（加拿大）和温水（中国）的藻类进行了总脂质含量、脂肪酸（FA）组成和含量分析。主要发现是，加拿大藻类的脂肪酸通常富含多不饱和脂肪酸（PUFA），具有更高的n-3/n-6脂肪酸比率和更高的总不饱和度。在冷水样本中检测到含量更高的18碳、4个双键脂肪酸（18 : 4 硬脂酸，别名莫诺酸）。加拿大藻类中总PUFA，尤其是n-3脂肪酸的高含量表明它们在营养方面具有潜在用途。
