Question

What is the biological significance of Lipids?

Answer 1

A lipid is a macro biomolecule that is soluble in nonpolar solvents in biology and biochemistry. Lipids are organic compounds that contain hydrogen, carbon, and oxygen atoms and serve as the structural and functional framework of living cells.

Complete answer:
Lipids are an organic compound family made up of fats and oils. These molecules have a lot of energy and are involved in a variety of functions in the human body. Lipids have a number of important characteristics, which are listed below.
Lipids are nonpolar oily or greasy molecules that are stored in the body's adipose tissue.
Lipids are a diverse group of compounds that are primarily made up of hydrocarbon chains.
Lipids are organic molecules that are high in energy and provide energy for a variety of life processes.
Lipids are a class of compounds distinguished by their insolubility in water and solubility in nonpolar solvents.
Lipids are important in biological systems because they form the cell membrane, which is a mechanical barrier that separates a cell from its surroundings.
Lipids have biological significance they are as follows–
Phospholipids, for example, are structural lipids that make up the material of biological membranes.
In hair, plants, fur, feathers, and other animals, it forms protective coverings for fruits, leaves, and other items.
They're kept as back-up food. Excess food is converted into fat and stored in the body.
Many physiological processes are controlled by steroids in the form of hormones.
In mammals such as whales, blubber – a subcutaneous fat deposition that serves as heat insulation and protection – is present.

Note:
Lipids play a role in the body as well as in food. Lipids serve as an energy reserve in the body, as well as regulating hormones, transmitting nerve impulses, cushioning vital organs, and transporting fat-soluble nutrients.
