What are the structural units of lipids?
The structural units of lipids are fatty acids, glycerol, and other components like phosphates or sterols. Fatty acids are long hydrocarbon chains with a carboxyl group at one end, while glycerol is a three-carbon alcohol that serves as the backbone for triglycerides. These units combine to form various types of lipids, such as triglycerides, phospholipids, and steroids.
Difference between non esterified fatty acids and free fatty acids?
Essentially, there is no difference. Some prefer to use the term non-esterified fatty acid (NEFA) compared with free fatty acid (FFA) because many find the term FFA confusing with respect to fatty acids that circulate within the bloodstream which are 'bound' to albumin, but not esterified to another chemical moiety compared with intracellular fatty acids that are not 'bound' to albumin which are also not esterified to another chemical moiety.
What is the difference between fat and fatty acids?
Fat is a broad term that refers to a type of nutrient that provides energy and helps with nutrient absorption. Fatty acids are specific components of fats that are essential for various bodily functions, such as cell structure and hormone production. In summary, fatty acids are a type of fat, but not all fats are fatty acids.
Why are essential fatty acids essential?
Essential fatty acids are essential because the human body cannot produce them on its own, so they must be obtained from the diet. These fatty acids play crucial roles in maintaining cell structure and function, supporting brain health, and regulating inflammation and blood clotting. Without an adequate intake of essential fatty acids, certain key bodily functions would be compromised.
What is a triglyceride?
A triglyceride is a type of fat found in blood and tissues. It consists of three fatty acid molecules attached to a glycerol backbone. Triglycerides are a major energy source for the body and are formed from excess calories consumed.
Is glycerol and glycogen part of fatty acids?
glycerol and fatty acids are lipids. monosaccharides are term used for carbohydrates.
What are the structural units of lipids?
The structural units of lipids are fatty acids, glycerol, and other components like phosphates or sterols.

These units combine to form various types of lipids, such as triglycerides, phospholipids, and steroids.
What compounds form fat?
Fats are composed of molecules called triglycerides, which are made up of glycerol and three fatty acids. The fatty acids are chains of carbon atoms bonded together with hydrogen atoms attached. The types of fatty acids present in a fat molecule determine its characteristics.
What are the main components of a lipid?
The two main functions of a lipid are long-term energy storage and cushioning for vital organs.
What does lipase break down?
Pepsin is found in the stomach, and breaks down long-chain proteins into shorter amino acids, whilst lipase is secreted into the duodenum by the pancreas to break down fats into their constituent parts: fatty acids and glycerol.
Which term describes the brokendown of stored fats into glycerol and fatty acids?
The term that describes the breakdown of stored fats into glycerol and fatty acids is "lipolysis." This process is primarily facilitated by enzymes called lipases and occurs in adipose tissue, where triglycerides are converted into free fatty acids and glycerol, which can then be used for energy production by the body. Lipolysis is a crucial metabolic pathway during periods of fasting or increased energy demand.
Can fatty acids and glycerol be used as sources of energy?
Yes. Fatty acids undergo beta oxidation and make acetyl coA, which goes through the TCA cycle until it reaches oxaloacetate. However, a fatty acid cannot be used to make new glucose. Glycerol can enter glycolysis by being converted into glyceraldehyde 3 phosphate.

Where do lipids store energy?
Lipids store energy in the form of triglycerides, which are made up of fatty acids and glycerol. These triglycerides are stored in adipose tissue throughout the body, serving as a long-term energy reserve that can be broken down for energy when needed.
Fats are made of fatty acids and?
AnswerFats are made of Triglyceride molecules. They are classified as lipids because they are hydrophobic, having a tendency to repel water. FATS ARE DANGEUROS YOU CAN GET FAT LIKE ME FROM THEM
