饱和脂肪酸

As tail-suspended rats model can form an abnormal model of lipid metabolism as well as bone metabolism, We added three levels offish oil to the diets of rats of this model to determine the effects of n-3 polyunsaturated fatty acids on lipid and bone metabolism, so as to determine the interaction of these two chronic diseases and clarify the mechanism of these diseases.

尾部悬吊模拟失重大鼠模型能够同时造成大鼠脂质代谢与骨代谢失调，而应用此模型进行脂质代谢与骨代谢失调相关关系及膳食(n-3)多不饱和脂肪酸干预对模拟失重条件下脂质与骨代谢的影响的研究尚未见报道。本实验通过添加以鱼油为来源的不同剂量的(n-3)多不饱和脂肪酸作为膳食干预手段，研究其对模拟失重条件下构建的大鼠脂质代谢与骨代谢异常的调节作用，以加强对脂质代谢与骨代谢相互作用生理进程的深入了解为目标，为阐明中老年人群慢性疾病并发或多发的生理生化机制提供一定的实验依据。

The method is thus a good one for obtaining individual unsaturated fatty acids in pure state.

及防止不饱和脂肪酸在分离过程中发生氧化和异构化的特点，是一种较理想的制备高纯度不饱和脂肪酸的方法。

The female silkworm moth also contained large amounts of unsaturated fatty acids, the largest among them was the linolenic acid belonging to the n-3 series, 40 times as much as that in eggs and 38 times as much as that in milk, while 6.5 times larger than linoleic acid.

家蚕雌蛾体含有丰富的不饱和脂肪酸，其中必需的n-3系列多不饱和脂肪酸亚麻酸含量最高(39.88%)，是鸡蛋的40倍和牛奶的38倍，并高于亚油酸含量6.5倍。

Unlike steaks and hamburgers, it's low in saturated fat, which raises "bad" cholesterol and may increase insulin resistance, making blood sugar control more difficult. A 3-ounce serving of skinless chicken breast has only 142 calories and 3 grams fat.

和牛排汉堡不同的是，它的饱和脂肪酸的含量很低，饱和脂肪酸可以升高胆固醇水平，还有可能抗胰岛素，使血糖的控制更困难。3盎司的无皮鸡胸脯只有142卡热量和3克脂肪。

GC analysis showed that showed that the changes of fatty acids of oyster during the storage at -18℃ were related to their degree of unsaturation.

结果表明，牡蛎中主要含有C_(14∶0)、C_(15∶0)、C_(16∶0)、C_(17∶0)、C_(18∶0)五种饱和脂肪酸和C_(16∶1)、C_(18∶1)、C_(18∶2)、C_(18∶3)、C_(20∶1)、C_(20∶5)、C_(22∶6)七种不饱和脂肪酸。

In recent years the role of fatty acids such as omega-3, present in oily fish including salmon and sardines, has been identified as important in producing children who are bright, dextrous and sociable.

这些年，像omega-3这种多元不饱和脂肪酸在使孩子聪明、灵活、友善的方面被认为起着重要的作用。油性鱼类中常常包含多元不饱和脂肪酸，像鲑鱼和沙丁鱼。

Main types of fatty acids found in the oils were normal saturated, mono-branched, multi-branched, cyclopropane, furanoid, normal monounsaturated and polyunsaturated fatty acids.

不饱和脂肪酸含量为73.6%，其中多不饱和脂肪酸含量为25.4%，以C18∶2(4.9%)，C18∶3(3.1%)，C20∶4(1.3%)，C20∶5(二十碳五烯酸， 9.4%)和C22∶6(二十二碳六烯酸， 6.7%)为主。

The lipid peroxidation of S. maxima cultured in the presence of 4 to 100mg Se/L analysed showed that the contents of free radicals by EPR and malondialdehyde increased, of which the latter was the products of lipid peroxidation. These resulted in the decrease of the contents of liposoluble matter and percentage of polyunsaturated fatty acids, and the increase of percentage of saturated fatty acids. Using dimethyl sulfoxide , which was oxidized by OH·to form the stable and nonradical compound, methane sulfinic acid , as a molecular probe, we found that the contents of MSA from S. maxima growing in the presence of selenium were higher than those without selenium added, i. e. selenium in vivo was able to scavenge OH. in this alga.

对4～100mg Se/L范围内培养的S.maxima进行脂质过氧化的分析结果表明，加硒条件下藻细胞EPR自由基的含量与脂质过氧化产物的含量增加，造成细胞脂溶性物质含量和不饱和脂肪酸百分含量下降，以及饱和脂肪酸的百分含量相对上升；使用DMSO作分子探针，用它与OH·的反应产物MSA来表示藻细胞OH·含量，发现加硒条件下藻细胞MSA含量低于未加硒的，即硒在藻细胞内具有清除OH·作用。

Unsaturated fatty acids including linoleic acid、γ-linolenic acid、 dihomo-γ-linolenic acid、 arachidonic acid and eicosapentaenoic acid have played important roles in prevention and treatment of heart disease and high blood pressure、 in the inflammatory area (for example, treatment of asthma、 arthritis and psoriasis) and for some cancer treatment Natural sources of UFAs are animal and plant, such as EPA in fish oils, arachidonic acid in porcine liver and y -linolenic acid in Oenothera biennis L..

不饱和脂肪酸包括亚油酸、γ-亚麻酸、双高γ-亚麻酸、花生四烯酸和二十碳五烯酸等在内对心脏疾病、高血压、炎症(如哮喘、关节炎和牛皮藓)和某些癌症的预防和治疗均有显著效果。不饱和脂肪酸的自然来源主要是动植物，如二十碳五烯酸存在于深海鱼油，花生四烯酸存在于猪肝而γ-亚麻酸多来源于月见草等植物种籽。

The results suggested that the oleic acid contents of high oleic acid parents and normal parents were stable.

单不饱和脂肪酸油酸的增加和多不饱和脂肪酸的减少，能够增加食用油的氧化稳定性，减少氧化产物。
