The metabolic elongation products of both linoleic acid and linolenic acid were found in muscle tissues of Syncerus caffer and other ruminants. The acids with four double bonds were predominantly in the linoleic acid series, whereas the higher degrees of unsaturation, mainly five double bonds, were in the linolenic acid series. The total linoleic acid and linolenic acid groups were present in the relative proportions of about 4:1, in contrast with the fish oils, where the acids are mainly in the linolenic acid series. The consistent occurrence of members of both groups of acids in the animals studied here suggests to us that both may be important for structural purposes.
在南非水牛和其他反刍动物的肌肉组织中发现了亚油酸和亚麻酸的代谢延长产物。具有四个双键的酸主要存在于亚油酸系列中,而更高程度的不饱和酸,主要是五个双键的酸,则存在于亚麻酸系列中。亚油酸和亚麻酸的总基团以约4:1的相对比例存在,这与鱼油不同,鱼油中的酸主要存在于亚麻酸系列中。在这里研究的动物中,两组酸的成员持续出现,这向我们表明两者对于结构目的可能都很重要。
