Detailed explanation-1: -Triglycerides are lipids you obtain from food sources, eg cooking oils, butter, animal fat, avocados, olives, corn, and nuts. Triglycerides provide insulation that keeps you warm while protecting your internal organs with a layer of padding. They also play a role how your body uses vitamins.

Detailed explanation-2: -Subcutaneous fat, or fat underneath the skin, insulates the body from extreme temperatures and helps keep the internal climate under control. It pads our hands and buttocks and prevents friction, as these areas frequently come in contact with hard surfaces.

Detailed explanation-3: -One type of lipid, the triglycerides, is sequestered as fat in adipose cells, which serve as the energy-storage depot for organisms and also provide thermal insulation.

Detailed explanation-4: -Lipids are fatty compounds that perform a variety of functions in your body. They’re part of your cell membranes and help control what goes in and out of your cells. They help with moving and storing energy, absorbing vitamins and making hormones. Having too much of some lipids is harmful.

Detailed explanation-5: -Lipids also provide insulation from the environment for plants and animals (Figure 12.1. 4. 1). For example, they help keep aquatic birds and mammals dry when forming a protective layer over fur or feathers because of their water-repellant hydrophobic nature.
