what is lipids in anatomy and physiology?

Lipids: Another word for "fats." (Please see the various meanings of Fat.) Lipids can be more formally defined as substances such as a fat, oil or wax that dissolves in alcohol but not in water. Lipids contain carbon, hydrogen and oxygen but have far less oxygen proportionally than carbohydrates.

Lipids are found in your blood and stored in tissues. Lipid disorders, such as high cholesterol, may lead to life-threatening illnesses, such as coronary artery disease, heart attack or stroke. A healthcare provider may order a lipid panel and use the results to prevent, check on or diagnose a medical condition.

Lipids include fats, oils, waxes, phospholipids, and steroids. A fat molecule, such as a triglyceride, consists of two main components—glycerol and fatty acids. Glycerol is an organic compound with three carbon atoms, five hydrogen atoms, and three hydroxyl (–OH) groups.

They can be found in many parts of a human: cell membranes, cholesterol, blood cells, and in the brain, to name a few ways the body uses them. Lipids are important for cell membrane structure, regulating metabolism and reproduction, the stress response, brain function, and nutrition.

Lipids consist of repeating units called fatty acids. Fatty acids are organic compounds that have the general formula CH3(CH2)nCOOH, where n usually ranges from 2 to 28 and is always an even number.

Every human cell has a protective, permeable membrane. Membranes contain two layers, each made mainly of proteins, cholesterol, and fats in the form of phospholipids. Phospholipids are almost the same as triglycerides, except that one of the three fatty acid units is replaced by a molecule that contains phosphorus.

Anatomy & Physiology. The Anatomy and Physiology module introduces the structure and function of the human body. You will read about the cells, tissues and membranes that make up our bodies and how our major systems function to help us develop and stay healthy.

Triglycerides, cholesterol and other essential fatty acids—the scientific term for fats the body can't make on its own—store energy, insulate us and protect our vital organs. They act as messengers, helping proteins do their jobs.

Anatomy deals with the body's structure, different parts like cells, tissues, organs and organ system, etc. Physiology deals with the working of the body's part and their specific roles.

Lipid Bilayer Structure The lipid bilayer is a universal component of all cell membranes. Its role is critical because its structural components provide the barrier that marks the boundaries of a cell. The structure is called a "lipid bilayer" because it is composed of two layers of fat cells organized in two sheets.

Phospholipids are major components of the plasma membrane, the outermost layer of animal cells. A cell's plasma membrane contain proteins and other lipids (such as cholesterol) within the phospholipid bilayer.

The simplest definition is a lipid as any molecule that is insoluble in water and soluble in organic solvents. Most lipids are soluble to some extent in organic solvents such as hexane, ether, chloroform or benzene.

Lipids perform three primary biological functions within the body: they serve as structural components of cell membranes, function as energy storehouses, and function as important signaling molecules.

Organisms use lipids to store energy, but lipids have other important roles as well. Lipids consist of repeating units called fatty acids. Fatty acids are organic compounds that have the general formula CH3(CH2)nCOOH, where n usually ranges from 2 to 28 and is always an even number.
