Lipids are a diverse group of organic molecules that are important components of living organisms. They are also commonly referred to as fats and oils. Lipids are polymers of fatty acids, containing long non-polar hydrocarbon chains and small polar regions containing oxygen, which are relatively insoluble in water. Lipids play many important roles in the human body, including as a source of energy, forming the structure of cell membranes, as signaling molecules, and as insulators that protect internal organs.
Types of Lipids
Among lipids, there are many specific types of lipids important for life, including fatty acids, triglycerides, glycerophospholipids, sphingolipids, and steroids. They are broadly classified as simple lipids and complex lipids.
Lipid Properties
The main characteristic common to all lipid molecules is that they are insoluble in water, as they are formed from ester bonds - which are compounds formed from alcohols and acids by removing a hydrogen atom from a water molecule. This makes lipids essential for building structures that must retain their shape when surrounded by liquids. This is why lipids are a key component of hormones - hormones are chemical messengers that must travel through a liquid medium. Their strong molecular bonds allow lipids to facilitate long-term energy storage.
Bonding to Carboxyl Groups
When a long chain carbon atom is attached to a carboxyl group, it is called a fatty acid. This is the simplest type of lipid polymer. The carboxyl group consists of a carbon atom that forms a double bond with an oxygen atom and a single bond with an oxygen atom that is bonded to another carbon atom. These chains make up the saturated and unsaturated fats found in plant and animal foods.
Binding to Glycerol
Fatty acids form more complex lipid polymers called triglycerides, triacylglycerols, or triacylglycerides when each single-bonded oxygen molecule is bonded to a carbon that is part of the glycerol molecule. Glycerol is a simple alcohol consisting of three oxygen atoms and three carbon atoms, bonded eight times to hydrogen atoms.
Bonding with Phosphate Groups
When a triglyceride replaces a fatty acid chain with a phosphate group, it forms a phospholipid. The phosphate group consists of a phosphorus atom bonded to an oxygen atom. Phospholipids form a characteristic bilayer structure in which a water-resistant or hydrophobic layer is sandwiched by a permeable or hydrophilic layer. They are the main components of cell membranes and intracellular membranes.
Functions of Lipids
Molecules in lipids not only provide structure to the cell membrane, but also store energy and play an important role in cell signaling and functional regulation. Defects in lipid metabolism can cause a variety of inherited metabolic diseases. Typically, the accumulation of abnormal lipids in the blood and tissues that damage cells lead to disorders of lipid metabolism. Accurate identification of abnormal lipids is the key to effective diagnosis and treatment.
Lipid in Drug Delivery
Lipid-based drug delivery systems have several advantages over other drug delivery systems. For example, they are biocompatible, biodegradable, and protect the drug from degradation and clearance by the body's immune system. Lipid-based drug delivery systems can also improve the solubility and bioavailability of insoluble drugs and can increase the circulation time of drugs in the body.
