Answer:
The correct answer is D. Lipophilic.
Step-by-step explanation:
Lipophilic is defined as having an affinity or attraction to fat and oils. The term comes from the Greek words "lipo," meaning fat, and "philos," meaning loving.
To understand this concept, let's break it down step by step. When a substance is lipophilic, it means that it is soluble in fat or oils, but not in water. This property is due to the nature of lipids, which are the main components of fats and oils.
For example, if you have ever tried to mix oil and water together, you may have noticed that they do not mix well. This is because oil is lipophilic and repels water. However, if you add a soap or detergent to the mixture, the lipophilic oil molecules can form emulsions with water, allowing them to mix together.
In the context of biology and chemistry, lipophilic substances can be important for various reasons. For instance, certain medications need to be lipophilic to effectively pass through cell membranes and reach their target sites within the body. Lipophilic compounds are also commonly used in cosmetics and skincare products to help moisturize and nourish the skin.
In summary, having an affinity or attraction to fat and oils is defined as lipophilic. This term is used to describe substances that are soluble in fats and oils, but not in water.
