BIOMOLECULES
LIPIDS
Lipids Definition
“Lipids are organic compounds that contain hydrogen, carbon, and
oxygen atoms, which form the framework for the structure and
function of living cells.”
Lipids
These organic compounds are nonpolar molecules, which are soluble only in
nonpolar solvents and insoluble in water because water is a polar molecule. In the
human body, these molecules can be synthesized in the liver and are found in oil,
butter, whole milk, cheese, fried foods and also in some red meats.
Let us have a detailed look at the lipid structure, properties, types and classification
of lipids.
Properties of Lipids
Lipids are a family of organic compounds, composed of fats and oils. These
molecules yield high energy and are responsible for different functions within the
human body. Listed below are some important characteristics of Lipids.
1. Lipids are oily or greasy nonpolar molecules, stored in the adipose tissue of
the body.
2. Lipids are a heterogeneous group of compounds, mainly composed of
hydrocarbon chains.
3. Lipids are energy-rich organic molecules, which provide energy for different
life processes.
