The body can synthesize most of the fats it needs from the diet. However, two essential fatty acids, linoleic and alpha-linolenic, cannot be synthesized in the body and must be obtained from food. These basic fats, found in plant foods, are used to build specialized fats called omega-3 and omega-6 fatty acids.
Also question is, do all lipids provide us with energy?
Your body uses fats as a supply and store of energy: a gram of fat contains more than double the amount of energy present in a gram of carbohydrate. The steroids in your body include some hormones. Other lipids make up the outer layer of all your cells, and the fatty sheaths that insulate nerve fibres.
What is the function of lipids in your body?
Lipids, also known as fats, play many important roles in your body, from providing energy to producing hormones. You wouldn't be able to digest and absorb food properly without lipids. Of course, eating more fat than you need can lead to weight gain, but in proper amounts lipids are a healthy part of your diet.
