Lipids and Their Functions

Triglycerides store energy for long-term use.

Phospholipids form cell membranes and myelin sheaths.

Saturated fats have single bonds between carbon atoms and solid at room temperature.

Trans fats are created through hydrogenation.

Cholesterol maintains cell membrane fluidity and is involved in hormone synthesis.

Lipids are mainly made up of fatty acids and glycerol. They are hydrophobic (water-repelling) and have many important roles in the body.

Fats are solid at room temperature, while oils are liquid. Both are types of lipids.

Triglycerides are made of one glycerol molecule and three fatty acid tails. They are the main way our body stores energy for a long time.

Phospholipids make up the cell membrane, like building blocks in a wall. They also form myelin sheaths around nerve cells.

Steroids are involved in communication between cells, like messengers.

Saturated fats have only single bonds between carbon atoms. They are solid at room temperature and often found in animal products.

Unsaturated fats have at least one double bond between carbon atoms. They are usually liquid at room temperature and found in plant products.

Trans fats are created when liquid oils are turned into solid fats through a process called hydrogenation. They are often found in processed foods and are considered unhealthy.

Lipoproteins are like delivery trucks for lipids. They carry them through the bloodstream.
