Give three function of lipids to human body ?

1. Energy storage: Lipids serve as a concentrated source of energy, providing more than twice the amount of energy per gram compared to carbohydrates or proteins. They are stored in adipose tissue and can be broken down and used for energy when needed.

2. Structural component of cell membranes: Lipids, specifically phospholipids, are a major component of cell membranes. They help maintain the integrity and fluidity of cell membranes, allowing for proper cell function and communication.

3. Hormone production: Lipids are involved in the production of various hormones in the body, such as steroid hormones like estrogen, testosterone, and cortisol. These hormones play important roles in regulating metabolism, growth, immune function, and other physiological processes.

1. Energy storage: Lipids are the body's primary energy reserve. They are broken down into fatty acids and glycerol, which are then used to produce energy for cells.

2. Insulation: Lipids help to insulate the body against heat loss. They are found in the skin, subcutaneous tissue, and around internal organs.

3. Hormone production: Lipids are precursors to a number of hormones, including testosterone, estrogen, and progesterone. These hormones are responsible for a variety of functions, including reproduction, growth, and development.
