請問腦磷脂的英文怎麼拼?
自己怎麼查都查不到
請大家幫幫忙
因為下禮拜要考試了拜託拜託

Answer 1

腦磷脂就是 Phosphatidylserine 縮寫為 P.S.

卵磷脂中的磷脂絲胺酸（phosphatidylserine，又稱腦磷脂）已被證實可以增加學習能力，主要是因為腦磷脂能增加腦細胞膜的流動性及腦細胞葡萄糖的濃度，這也同時代表他能使腦細胞更活躍，卵磷脂中的磷脂質同時也具有強化細胞膜對自由基破壞性的抵抗力，減少細胞老化變性的機率。

Answer 2

cephalin: Cephalin is a phospholipid, which is a lipid derivative.
Although it is found in all living cells, it is found particularly in nervous tissue such as the white matter of brain, nerves, neural tissue, and in spinal cord. Whereas Lecithin is the principal phospholipid in animals, cephalin is the principal one in bacteria. Its role in nature seems uncertain.

In the chemical sense, cephalin is phosphatidyl-ethanolamine. Like Lecithin, it consists of a combination of glycerol esterified with two fatty acids and phosphoric acid. Whereas the phosphate group is combined with choline in Lecithin, it is combined with the ethanolamine in Cephalin.

The two fatty acids may be the same, or different, and are usually in the 1,2 positions (though can be in the 1,3 positions).

腦磷脂Phosphatidylserine顧名思義就是存在腦部的磷脂質，腦磷脂主要是由卵磷脂中提煉出來的，不過天然的卵磷脂所含的腦磷脂濃度其實很低，天然食物中也很少含有這個成分，腦磷脂已被醫學臨床上證實具有改善阿茲海默氏症（老年性痴呆症）的作用，雖然腦磷脂不能治癒阿茲海默氏症，但卻可以有效的減緩惡化的速度，臨床試驗亦證實，腦磷脂可以改善老年人的記憶力減退現象及老人憂鬱症，腦磷脂主要的作用是在提升腦細胞膜的穩定性，免受老化現象（自由基的作用）的破壞。
