n-3 Dietary polyunsaturated fatty acidsProspective epidemiological surveys and numerous animal studies have shown an important role for dietary docosahexaenoic acid (DHA) in healthy brain function and reducing the risk of dementia. The evidence for this is summarised and some further experiments of our...
真正的鳕鱼、太平洋比目鱼和明太鱼的DHA含量较低,在安全食量范围内补充Omega-3的量十分有限。(明太鱼比另外两者略强) 大家最关心的黑鳕鱼和法国银鳕鱼,12.5kg儿童(也就是差不多一两岁孩子)的每周安全摄入量居然只有25克(也就是差不多只有半个鸡蛋的重...
原因有以下两个方面:一是提高DHA的吸收效率:当人体同时摄入甘油三酯型DHA和富含极性脂质的拟微球藻油时,拟微球藻油中的极性脂会乳化甘油三酯型DHA,使其在肠道中与消化酶更充分接触,从而更容易被水解,提高DHA的吸收效率。二是增加DHA与极性...
The H03B1 MAG also encodes a formate dehydrogenase subunit A gene (fdhA) co-located with a fdhB gene (Supplementary Table 7) and a putative b-type cytochrome with five transmembrane helices and a prokaryotic b561 domain (PF01292) binding two heme groups (Supplementary Fig. 11c) that is ...

Omega-3 fatty acid concentrate from Dunaliella salina possesses anti-inflammatory properties including blockade of NF-魏B nuclear translocationThe health benefits of omega-3 polyunsaturated fatty acids (ω-3 PUFA), mainly eicosapentaenoic acid (EPA 20:5) and docosahexaenoic acid (DHA, 22:6), have ...
因此,CLA也被称为继α-亚麻酸、二十碳五烯酸(EPA)和二十二碳六烯酸(DHA)之后的又一种功能性脂类物质。尽管对于CLA的具体作用机理目前仍不清楚,但已有研究报道不同CLA异构体(C=C位置和构型不同)具有不同的作用。因此,发展CLA异构体的快速鉴定和定量分析方法,对于在分子层面揭示其作用机制具有重要意义。然而,合成...
Myristoylation, the N-terminal modification of proteins with the fatty acid myristate, is critical for membrane targeting and cell signaling. Because cancer cells often have increased N-myristoyltransferase (NMT) expression, NMTs were proposed as anti-ca
Solubilisation experiments revealed that the mismatch between the C10-tail of n-decanol with the DHAB-tails does not affect the structural integrity of the vesicles. On the contrary, upon increasing amounts of cetyl alcohol, of which the tail matches in size with the DHAB-tails, breakdown of...
