Detailed explanation-1: -The different varieties of lipids have different structures, and correspondingly diverse roles in organisms. For instance, lipids store energy, provide insulation, make up cell membranes, form water-repellent layers on leaves, and provide building blocks for hormones like testosterone.

Detailed explanation-2: -Fats are used to store energy within their chemical bonds. They also serve as insulation in organisms that maintain a constant body temperature, such as mammals and birds. The building blocks of fats are triacylglycerol molecules. These molecules are composed of one glycerol and three fatty acids.

Detailed explanation-3: -Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals.

Detailed explanation-4: -Lipids provide long-term energy storage, form cell membranes (phospholipids). The provide insulation, and cushioning of internal organs, and partake in the messaging process in the body (hormones).

Detailed explanation-5: -Triglycerides, cholesterol and other essential fatty acids-the scientific term for fats the body can’t make on its own-store energy, insulate us and protect our vital organs. They act as messengers, helping proteins do their jobs.
