b. glycolipids
c. sterols
d. triacylglycerides

Answer 1

Phospholipids type of lipids are the most abundant in the plasma membrane.

What is phospholipids?

• Phospholipids are a subclass of lipids that have two hydrophobic "tails" made of fatty acids connected by an alcohol residue, one of which is a hydrophilic "head" containing a phosphate group.
• Omega-3 fatty acids EPA and DHA are frequently incorporated into the phospholipid molecule of marine phospholipids.
• Phospholipids are compound lipids made of alcohol, fatty acids, nitrogen base, and phosphoric acids.
• These intricate lipids, which also give the membranes their fluidity, make up the majority of the cell membrane.
• A class of polar lipids known as phospholipids (PL) is made up of two fatty acids, a glycerol unit, and a phosphate group that is esterified to an organic molecule (X) like choline, ethanolamine, inositol, etc.
• Esters of glycerol, fatty acids, phosphoric acid, and other alcohols make up phospholipids.
• Phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidylserine are the four most prevalent phospholipids.
