Phospholipid powder preferential price, the importance of animals

Phospholipids play an extremely important role in animals, mainly reflected in the following aspects:

An Essential Component of Biological Membranes: Phospholipids are the basic framework for constructing the biological membranes of animal cells. Biological membranes include cell membranes, organelle membranes, etc. They separate various structures within the cell, providing a stable internal environment for the cell. The phospholipid bilayer has fluidity and semi-permeability. It can not only maintain the shape of the cell but also selectively allow certain substances to enter and exit the cell, thus ensuring the normal metabolic and physiological functions of the cell. For example, the phospholipids on the cell membrane allow small molecular substances such as oxygen and carbon dioxide to pass freely, while preventing some large molecular substances and ions from entering and leaving the cell randomly.

Participation in Substance Transport: Inside the cell, phospholipids are involved in the transport processes of various substances. For example, vesicles composed of phospholipids can encapsulate substances such as proteins and lipids and transport them within the cell, carrying these substances from the synthesis site to where they are needed. In addition, on the cell membrane, some phospholipid molecules can also act as carriers to assist the transmembrane transport of certain substances. For instance, phosphatidylcholine and others can participate in the absorption and transport of nutrients such as fatty acids, ensuring the intake and utilization of nutrients by the animal body.

Energy Storage and Metabolism: Glycerophospholipids in phospholipids can be decomposed in the animal body to generate energy. When the animal needs energy, glycerophospholipids will be hydrolyzed, releasing fatty acids and other components. Fatty acids can further produce ATP through pathways such as β-oxidation, providing energy for the life activities of the animal. At the same time, the metabolic process of phospholipids is also closely related to fat metabolism, carbohydrate metabolism, etc., and participates in regulating the energy balance in the animal body. For example, in fat metabolism, phospholipids help with the emulsification and transport of fats, promoting the digestion and absorption of fats.

Signal Transduction: Phospholipids play an important role in cell signal transduction. Some phospholipid molecules can be hydrolyzed by enzymes inside the cell to produce second messengers, such as diacylglycerol (DAG) and inositol trisphosphate (IP3). These second messengers can activate the signaling pathways inside the cell and regulate physiological processes such as cell growth, differentiation, and apoptosis. For example, when an animal is stimulated by the outside world, phosphatidylinositol 4,5-bisphosphate (PIP2) on the cell membrane will be hydrolyzed by phospholipase C to generate DAG and IP3. DAG can activate protein kinase C (PKC), and IP3 can prompt the endoplasmic reticulum to release calcium ions, thus triggering a series of cellular responses.

Protective and Lubricating Effects: On the surface of some organs and tissues of animals, phospholipids can form a protective film, playing a role in protection and lubrication. For example, on the surface of the alveoli, there is a surfactant composed of phospholipids and other substances. It can reduce the surface tension of the alveoli, prevent the alveoli from collapsing during exhalation, and ensure the normal gas exchange function of the lungs. At the same time, in the joint cavity of animals, phospholipids also help reduce the friction between joints, playing a role in lubricating and protecting the joints.
