phospholipids are esters of glycerol witha)two carboxylic acid residue...
Phospholipids are a class of lipids that are structurally similar to triglycerides, except that one of the fatty acid chains is replaced by a phosphate group. They are a major component of cell membranes and play a crucial role in maintaining the integrity of the membrane.
Structure of Phospholipids:
Phospholipids are esters of glycerol, a 3-carbon alcohol, with two fatty acid chains and a phosphate group. They have a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail. The hydrophilic head contains a phosphate group and is polar, while the hydrophobic tail consists of two fatty acid chains and is nonpolar. This structure allows phospholipids to form a bilayer in aqueous solutions, such as cell membranes.
Esters of Glycerol with Two Carboxylic Acid Residues and One Phosphate Group:
The correct answer is option 'A', which states that phospholipids are esters of glycerol with two carboxylic acid residues and one phosphate group. This means that two of the hydroxyl groups (-OH) on the glycerol molecule are esterified with fatty acid chains, while the third hydroxyl group is esterified with a phosphate group. The carboxylic acid residues are derived from the fatty acids, which are long-chain carboxylic acids.
Conclusion:
In summary, phospholipids are esters of glycerol with two fatty acid chains and a phosphate group. They have a hydrophilic head and a hydrophobic tail, which allows them to form a bilayer in aqueous solutions. The correct answer to the given question is option 'A', which states that phospholipids are esters of glycerol with two carboxylic acid residues and one phosphate group.

phospholipids are esters of glycerol witha)two carboxylic acid residue...
Phospholipids are esters of glycerol, fatty acids, phosphoric acid, and other alcohols. These phospholipids share the common features of fatty acids(carboxylic acid residues) esterified to the 1 and 2 positions of the glycerol backbone and the phosphate group esterified to the 3 position. so, option a is correct.
