Sometimes high triglycerides are a side effect of taking certain medications, such as:
- Diuretics
- Estrogen and progestin
- Retinoids
- Steroids
- Beta blockers
- Some immunosuppressants
- Some HIV medications
What are two structural components of triglyceride?
What are the three functions of triglycerides?

What are the four components of a triglyceride?
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.
What is made up of a triglyceride?
Triglycerides are tri-esters consisting of a glycerol bound to three fatty acid molecules. Triglycerides are the main constituents of vegetable fat and body fat in humans and other animals.
What are the 3 components of triglyceride?
A triglyceride (TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids (from tri- and glyceride).
What is a triglyceride composed of quizlet?
Triglycerides are composed when one glycerol chain and three fatty acid chains are covalently bonded through dehydration synthesis by removing water to combine the molecules. The fatty acid is composed of 4-24 carbon atoms linked to a carboxyl group (-COOH) at one end and methyl (-CH3) at the other end.
Glycerol
Glycerol is the central component of a triglyceride molecule, as described by Dr. Neil Campbell and his colleagues in “Biology.” A glycerol molecule contains three carbon atoms and three hydroxyl groups, which are a unit of oxygen and hydrogen. A hydroxyl group is represented by –OH in chemistry notation.
Fatty Acids
A triglyceride contains three fatty acids. A fatty acid contains a carboxylic acid and a chain of carbon and hydrogen atoms. Carboxylic acid is made of at least one carboxyl group, which is made up of one carbon atom, two oxygen atoms and one hydrogen atom. In chemistry notation, a carboxyl group is represented by the notation –COOH.
Overall Structure
A triglyceride is a combination of a glycerol molecule and three fatty acids. In each fatty acid, a carbon atom from the carboxyl group binds to an oxygen atom from each of the three hydroxyl groups in the glycerol molecule.
What are triglycerides made of?
Triglycerides are tri-esters consisting of a glycerol bound to three fatty acid molecules. Alcohols have a hydroxyl (HO–) group. Organic acids have a carboxyl (–COOH) group. Alcohols and organic acids join to form esters. The glycerol molecule has three hydroxyl (HO–) groups and each fatty acid has a carboxyl group (–COOH).
What is the left part of a triglyceride?
Left part: glycerol; right part, from top to bottom: palmitic acid, oleic acid, alpha-linolenic acid. A triglyceride ( TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids (from tri- and glyceride ). Triglycerides are the main constituents of body fat in humans and other vertebrates, ...
What are the different types of fatty acids?
Some common examples of fatty acids: 1 Butyric acid with 4 carbon atoms (contained in butter) 2 Lauric acid with 12 carbon atoms (contained in coconut oil, palm kernel oil, and breast milk) 3 Myristic acid with 14 carbon atoms (contained in cow's milk and dairy products) 4 Palmitic acid with 16 carbon atoms (contained in palm oil and meat) 5 Stearic acid with 18 carbon atoms (also contained in meat and cocoa butter)
How many carbons are in a medium chain fatty acid?
Medium-chain fatty acid ( MCFA) with 6 to 12 carbons (e.g. capric acid ). Long-chain fatty acids ( LCFA) with 13 to 21 carbons (e.g. petroselinic acid ). A triglyceride molecule may have fatty acid elements of different lengths, and a fat product will often be a mix of various triglycerides.
What is the role of the pancreatic lipase in the lipid bond?
The pancreatic lipase acts at the ester bond, hydrolyzing the bond and "releasing" the fatty acid. In triglyceride form, lipids cannot be absorbed by the duodenum. Fatty acids, monoglycerides (one glycerol, one fatty acid), and some diglycerides are absorbed by the duodenum, once the triglycerides have been broken down.
Why are triglycerides present in the blood?
They are also present in the blood to enable the bidirectional transference of adipose fat and blood glucose from the liver, and are a major component of human skin oils. Many types of triglycerides exist. One specific classification focuses on saturated and unsaturated types. Saturated fats lack C=C groups.
What are fats named after?
Fats are usually named after their source (like olive oil, cod liver oil, shea butter, tail fat) or have traditional names of their own (like butter, lard, ghee, and margarine ). Some of these names refer to products that contain substantial amounts of other components besides fats proper.

In chemistry and biochemistry, dozens of saturated fatty acids and of hundreds of unsaturated ones have traditional scientific/technical names usually inspired by their source fats (butyric, ca…

Triglycerides are tri-esters consisting of a glycerol bound to three fatty acid molecules. Alcohols have a hydroxyl (HO–) group. Organic acids have a carboxyl (–COOH) group. Alcohols and organic acids join to form esters. The glycerol molecule has three hydroxyl (HO–) groups and each fatty acid has a carboxyl group (–COOH). In triglycerides, the hydroxyl groups of the glycerol join the ca…
Interactive pathway map
Fats can be classified according to the lengths of the carbon chains of their constituent fatty acids. Most chemical properties, such as melting point and acidity, vary gradually with this parameter, so there is no sharp division. Chemically, formic acid (1 carbon) and acetic acid (2 carbons) could be viewed as the shortest fatty acids; then triformin would be the simplest triglyceride. However, the terms "fatty acid" and "fat" are usually reserved for compounds with su…

Linseed oil and related oils are important components of useful products used in oil paints and related coatings. Linseed oil is rich in di- and tri-unsaturated fatty acid components, which tend to harden in the presence of oxygen. This heat-producing hardening process is peculiar to these so-called drying oils. It is caused by a polymerization process that begins with oxygen molecules attacking the carbon backbone.
