what are lipids?? In detail
Answers
Answer:
Lipids are oily or greasy nonpolar molecules, stored in the adipose tissue of the body. Lipids are a heterogeneous group of compounds, mainly composed of hydrocarbon chains. Lipids are energy-rich organic molecules, which provide energy for different life processes.
The three primary types of lipids are phospholipids , sterols, and triglycerides . They each play a different role in the body.
Within the body, lipids function as an energy reserve, regulate hormones, transmit nerve impulses, cushion vital organs, and transport fat-soluble nutrients.
Answer:
Definition
A lipid is chemically defined as a substance that is insoluble in water and soluble in alcohol, ether, and chloroform
Monomer
Glycerol and fatty acids are the monomers of lipids.
Elements
Lipids are composed of carbon, hydrogen and oxygen atoms, and in some cases contain phosphorus, nitrogen, sulfur and other elements.
Food source
Food Sources of Lipids
Commonly consumed oils are canola, corn, olive, peanut, safflower, soy, and sunflower oil. Foods rich in oils include salad dressing, olives, avocados, peanut butter, nuts, seeds, and some fish. Fats are found in animal meat, dairy products, and cocoa butter.
Functions
The main biological functions of lipids include storing energy, as lipids may be broken down to yield large amounts of energy. Lipids also form the structural components of cell membranes, and form various messengers and signaling molecules within the body.
