Matching Type. Match column A from Column B. Write your answer on space

### Lipids: An Essential Biological Molecule **Lipids** are commonly known as the storing energy for later use. They are found in hormones and membrane components of the cell. Lipids have different structural types such as **carboxylic acids or fatty acids, triglycerides or neutral fats, steroids, and waxes**. Naturally occurring esters are lipids that contain one or more long-chain carboxylic acids called **fatty acids**. These are insoluble in water but soluble in nonpolar solvents. The most abundant of the lipids are the **fats and oils**, also called **triglycerides**. Fats are solid at room temperature and contain saturated fatty acids, which are basically produced by animals. Animal fats include **lard** and **butter**. Oils are liquid at room temperature and contain unsaturated fatty acids. Most oils, such as **vegetable oils, corn oil, palm oil**, and **olive oils**, are produced by plants. If you eat in moderation, fats are good sources of body fuel. They are considered good emergency food and are an efficient energy storage system. However, an excessive quantity of fats intake is not good for the heart. The reasons why fats are not good for the heart is because they tend to **clog arteries** and overwork the heart. ### Steroids and Cholesterol **Steroids** are another class of lipids, and the most important steroid is **cholesterol**. It is a **sterol** because of the presence of an alcohol or the hydroxyl functional group. It is found mainly in animal cells, and a small amount of this may also be found in plant cells. Refer to the diagram below: #### Structure of Cholesterol [Diagram of Cholesterol] This diagram represents the molecular structure of cholesterol. Cholesterol plays an important role in eukaryotes and especially is abundant in the cell membrane of animal cells. Small amounts of cholesterol can also be found in the membrane of some organelles inside the cells, such as the **mitochondria** and the **endoplasmic reticulum**. It is also found in nerve cells. **Myelin** covers nerve axons to help conduct the electrical impulse that makes movement, sensation, thinking, learning, and remembering possible. Animals can also use cholesterol to synthesize other steroids like **cortisone, testosterone**, and **estrogen**, which are essential for the process of reproduction.

### Match the Following: Lipids and Their Functions ### Column A 1. **Lipids** 2. **Triglycerides** 3. **Steroids** 4. **Fats** 5. **Cholesterol** ### Column B a. fats and oils b. storing energy c. Cholesterol d. essential lipid for humans e. source of body fuel Students are to match each item in Column A with the most accurate description from Column B that corresponds to it. This exercise helps in understanding the various types of lipids and their specific functions or characteristics within biological systems.
