It got me a good grade Ohh this report is so good!


The subject I will cover is lipids. I will tell you about the description of it's organic compound. I will tell you where it is found. I will tell you what the uses are in plants and animals. I will also tell you about it's chemical structure and give examples of types of these compounds, such as cholesterol.

The organic compound of lipids have many similarities. They are almost always greasy, fatty, oily, or waxy. They do not dissolve in water, but they do in other organic solvents. This is like if you get grease on your hands it is hard to wash of because it seems to repel the water.

Lipids are always found in fat because when you get a build up of lipids it forms fat.

Lipids have many uses amongst plants and animals. The main use of these are for energy and storing energy. When they store energy they make triglycerides also known as fat. There are also many other uses such as insulation and protection. They are also used in making cell membranes. They make it so that the cell can maintain it's shape by keeping water and water-soluble compounds from passing through it. The lipids that are waxy are usually used to make protective coatings on the surface of plants and animals.

Since a lipid is an organic compound it contains carbon. They also contain hydrogen and oxygen, but in some very complex chains there is also phosphorus and/or nitrogen. Lipids are made by the dehydration synthesis...
