How are triglycerides classified?

Triglycerides belong to “glycerides”, a group of esters formed from glycerol reacting with fatty acids. They are classified based on the number of fatty acids reacting with glycerol. Thus, a triglyceride would have three fatty acids reacting the hydroxyl functional group of the glycerol.

What are the two classes of triglycerides?

Triglycerides are composed of glycerol and fatty acids. They exist as solid fats or liquid oils at room temperature. They are classified as simple or mixed triglycerides based on they type of fatty acid that is present in the molecule.

Is triglyceride a classification of lipids?

Lipids are made up of a glycerol molecule attached to three fatty acid molecules. Such a lipid is called triglyceride.

What are the 3 fatty acids in triglyceride?

Triglycerides are esters in which three molecules of one or more different fatty acids are linked to the alcohol glycerol; they are named according to the fatty acid components; e.g., tristearin contains three molecules of stearic acid, and oleodistearin, one of oleic acid and two of stearic acid.

What are 3 functions of triglycerides?

Fat Functions

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.

What are saturated and unsaturated triglycerides?

The key difference between saturated and unsaturated triglycerides is that saturated triglycerides have only single bonds between carbon atoms, whereas unsaturated triglycerides have double or triple bonds between carbon atoms.

What is a characteristic of triglycerides?

Characteristics. Triglycerides are the most common lipid found in the body. They contain three chains of fatty acids. Although similar in structure to the phospholipids that build cell membranes, triglycerides are completely hydrophobic, meaning they cannot mix with water, so they cannot integrate into membranes.

What are examples of triacylglycerol?

This includes all the vegetable oils, such as those from corn (maize), olive, palm, and sunflower, and animal fats, such as tallow, lard and butter, as well as manufactured products such as margarines.

Why are lipids called triglycerides?

One type of lipid is called a triglyceride, an ester derived from glycerol combined with three fatty acid molecules.

What is triglyceride?

Triglycerides are a type of fat. They are the most common type of fat in your body. They come from foods, especially butter, oils, and other fats you eat. Triglycerides also come from extra calories.

What is the structure and function of triglycerides?

Triglycerides are excellent long-term energy storage molecules because they will not mix with water and break down. We can also eat them (in delicious fried foods) and break them down to get energy. They are made of a glycerol backbone attached to three fatty acid chains.

What are simple and mixed triacylglycerols?

A triacylglycerol with three identical fatty acids is termed a simple triacylglycerol. These are exceedingly rare in nature. A triacylglycerol with two or three different fatty acids is termed a mixed triacylglycerol and makes up the bulk of the fat.

What is the difference between triacylglycerol and triglyceride?

The main difference between triacylglycerol and triglyceride is that triacylglycerol is the correct chemical name for an ester derived from glycerol bound to three fatty acids whereas triglyceride is the common name for the substance. Triglycerides are the main constituent of the animal and vegetable fats in the diet.

How do you tell if a triglyceride is saturated or unsaturated?

Saturated and unsaturated fatty acids
  1. If there are only single bonds between neighboring carbons in the hydrocarbon chain, a fatty acid is said to be saturated. …
  2. When the hydrocarbon chain has a double bond, the fatty acid is said to be unsaturated, as it now has fewer hydrogens.

What are the components of triglycerides?

A triglyceride is composed of glycerol and three fatty acids. When all of the fatty acids in a triglyceride are identical, it is termed a “simple” triglyceride. The more common forms, however, are the “mixed” triglycerides in which two or three kinds of fatty acids are present in the molecule.
