Question

An example of a lipid. Describe the use of lipids in humans.

Answer 1

Answer:  Lipids, as a class of compounds, are insoluble in water but are soluble in other organic solvents. Examples of such solvents include acetone and ether. Waxes, steroids, phospholipids, and fats

Explanation:

Answer 2

Answer:

Examples of lipids include:  Waxes, Oils, Sterols, Cholesterol, fat-soluble Vitamins (such as A, D, E and K), Monoglycerides, Diglycerides, Triglycerides (fats), and Phospholipids.

Use of Lipids in humans: Lipids perform functions both within the body and in food. Within the body, lipids function as an energy reserve, regulate hormones, transmit nerve impulses, cushion vital organs, and transport fat-soluble nutrients. Fat in food serves as an energy source with high caloric density, adds texture and taste, and contributes to satiety.

1.) Energy Storage:  The excess energy from the food we eat is digested and incorporated into adipose tissue, or fat tissue. Most of the energy required by the human body is provided by carbohydrates and lipids. Glucose is stored in the body as glycogen. While glycogen provides a ready source of energy, lipids primarily function as an energy reserve.

2.) Transporting : Fat-soluble nutrients are important for good health and exhibit a variety of functions. Vitamins A, D, E, and K—the fat-soluble vitamins—are mainly found in foods containing fat. Fat-soluble nutrients require fat for effective absorption. These vitamins are best absorbed when combined with foods containing fat.
