Phosphatidylglycerol is a glycerophospholipid found in pulmonary surfactant [1] and in the plasma membrane where it directly activates lipid-gated ion channels. The general structure of phosphatidylglycerol consists of a L-glycerol 3-phosphate backbone ester-bonded to either saturated or unsaturated fatty acids on carbons 1 and 2.

Phosphatidylglycerol (PG) is a ubiquitous lipid that can be the main component of some bacterial membranes, and it is found also in membranes of plants and animals where it appears to perform specific functions.

2024年9月25日 · Mechanistic studies revealed that AD1b targeted the membrane phospholipids phosphatidylglycerol (PG) and cardiolipin (CL), leading to the disruption of the bacterial membrane and proton motive force, metabolic disturbance, leakage of cellular components, and, ultimately, cell death.

Lysyl-phosphatidylglycerol (lysyl-PG) is a major membrane lipid (20 to 40%) in Staphylococcus aureus, while ornithyl-PG is present in Mycobacterium tuberculosis and alanyl-PG in Clostridium perfringens.

2024年10月1日 · Phosphatidylglycerol (PG) is an anionic phospholipid, a constituent of biomembranes and an important component of drug delivery formulations and modern vaccines. Its mixtures with phosphatidylcholine (PC) exhibit non-linear properties, which are usually attributed to the molecular immiscibility of PG and PC.

2015年6月30日 · Phosphatidylglycerol (PG) and cardiolipin (CL) are synthesized in mitochondria and regulate numerous biological functions. In this study, a novel fluorometric method was developed...

Phosphatidylglycerol (PG) is an anionic lipid found in mammalian membranes in low amounts. It is the second most abundant lipid in lung surfactant and is used to determine the maturity of a baby's lung. In animals, PG serves as a precursor for mitochondrial cardiolipin and plays a minor role in animal membranes.

2023年9月25日 · 磷酸甘油酯（Phosphatidylglycerol，简称PG）是一种磷脂类脂质分子，通常存在于生物体内，尤其是在细胞膜中。 磷酸甘油酯的分子结构. 磷酸甘油酯由1分子甘油中的3个羟基分别于1分子的十八酸、1分子十八烯酸和1分子磷酸胆碱中的3个羧基发生脱水缩和反应生成。 十八酸即分子中含有18个碳原子的饱和直连羧酸，又称硬脂酸。 十八烯酸由于分子中含有代表烯烃结构特征的碳碳双链而得名。 当甘油与其他种类的羧酸和磷脂衍生物发生这样的反应时便会得到 …

Phosphatidylglycerol (PG) is a type of glycerophospholipid, a class of lipids that are key components of biological membranes. It is composed of a glycerol backbone bonded to two fatty acid chains and a glycerol phosphate headgroup. PG is most notably found in bacterial membranes and in the inner mitochondrial membranes of eukaryotic cells.
