Phosphatidyl Choline
The phosphatidyl cholines, or PCs, are abundant phospholipids in animal and plant cells. |
ホスファチジルコリン（PC）は動物・植物の細胞における主要なリン脂質です。 |

- Functions
PC is a major membrane lipid and also a signalling agent. Its hydrolysis by phospholipases C and D proceeds in response to agonists such as platelet-derived growth factor (PDGF) and it produces phosphatidic acid and phosphocholine. |
ホスファチジルコリンは膜だけでなくシグナル物質としても働きます。血小板由来増殖因子などのアゴニストに対してホスホリパーゼCまたはDにより加水分解され、二次メッセンジャーであるホスファチジン酸を産生します。 |
- Essentiality
Chlamydomonas reinhardtii completely lack PCs, and its functions are complemented with diacylglyceryltrimethyl-homoserine (DGTS).[1][2] Other chlamydomonas species contain both PCs and DGTSs. |
Chlamydomonas reinhardtii はPCを全く持たず、その機能はジアシルグリセリルトリメチルホモセリン (DGTS) で代替されています。他のクラミドモナスは PC も DGTS も持っています。 |
