Phospholipids and sterols are very important for human diet.
- Phospholipids are molecules connected to fat that include phosphorus, fatty acids, and a base that contains nitrogen.
- They have a glycerol backbone similar to triglycerides, but instead of three fatty acids, it is joined to two fatty acids and a phosphorus group.
- Phospholipids are crucial molecules since they make up a crucial part of cell membranes. They support the flexibility and lack of rigidity of organelle and cell membranes.
- As the majority of a cell's membrane, phospholipids are crucial for cells.
- Sterols have a distinctive four-ring structure with carbon and hydrogen atoms as its main building blocks.
- The most well-known sterol is cholesterol, which is essential for cell membrane formation and the building block of many significant chemicals in the body.
