What are the four major phospholipids present in the plasma membrane of mammalian cells?
The four major phospholipids present in plasma membrane of mammalian cells are: 1. Phosphatidylcholine 2. Phosphatidylethanolamine 3. Phosphatidylserine 4. Sphingomyelin. For more details click on the link below.
What is the net charge of phosphatidylserine in physiological pH?
In physiological pH (around 7.4), phosphatidylserine typically carries a net negative charge due to the presence of its phosphate group. The head group of phosphatidylserine contains a negatively charged phosphate, which contributes to this overall charge. As a result, phosphatidylserine is often classified as an anionic phospholipid in biological membranes.
Predominant lipids in the lipid bilayer?
The predominant lipids in the lipid bilayer are phospholipids. These include phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and sphingomyelin. These lipids have a hydrophilic head and hydrophobic tail, allowing them to form the stable bilayer structure of cell membranes.
What are the two like charges?
a positive and a positive or a negative and a negative. Object with the same charge. Like charges repel each other.
When there is full of negative charges in a jar are there going to be negative charges?
No, if a jar is already full of negative charges, adding more negative charges would result in repulsion among the charges and likely lead to discharge or redistribution of charges. The negative charges would try to move away from each other to minimize repulsion.
Lipids that contain phosphorous in the form of phospate are?
Phospholipids contain phosphorus in the form of phosphate. They are a class of lipids that are major components of cell membranes. Examples include phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine.

What are the consitituents of phosphoglycerides?
Phosphoglycerides are composed of a glycerol molecule, two fatty acid chains, and a phosphate group. The phosphate group is linked to another molecule, such as choline, serine, or ethanolamine, forming different types of phosphoglycerides like phosphatidylcholine, phosphatidylserine, or phosphatidylethanolamine.
Do negative and Negative attract or repel each other?
Negative charges (like charges) repel each other due to the fundamental property of electromagnetism that like charges repel. Negative charges are attracted to positive charges.
Which of these will different charges do?
Positive charges attract negative charges and repel other positive charges. Negative charges do the opposite, attracting positive charges and repelling other negative charges. Like charges repel and opposite charges attract.
What are the 2 types of electric charges?
The two types of electric charges are positive and negative. Positive charges repel each other, as do negative charges, while positive and negative charges attract each other.
What is the difference between lecithins and cephalins?
Lecithins are a type of phospholipid that contain phosphatidylcholine, while cephalins are a type of phospholipid that contain phosphatidylethanolamine and phosphatidylserine. Both are important components of cell membranes but have slightly different compositions and functions.
Is mackerel a source of phosphatidylserine?
Yes, atlantic mackerel contains around 480 mg phosphatidylserine per 100 gram.
