What are the parts of 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 4 molecules make up a 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 triglycerides four?
Triglycerides are a type of fat found in the blood. They are the most common type of fat in the body. Triglycerides are necessary for health but in excess amounts, they may be harmful and may increase the risk of heart disease.
What are the main components of triglyceride lipids?
Triglycerides are composed of a glycerol molecule bound to three fatty acids and are digested by pancreatic lipase. Triglycerides are a major component of very-low-density lipoprotein (VLDL) and serve as a source of energy.
What are the components of a triglyceride quizlet?
What are the components of a triglyceride? A molecule of glycerol and 3 fatty acids.
What are the three triglycerides?
The three types of fatty acids that compose triglycerides are saturated, monounsaturated and polyunsaturated fatty acids. From these three types of fatty acids come the three types of triglycerides, or fats; saturated, monounsaturated and polyunsaturated triglycerides.
What are triglycerides 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.
What are the 3 types of triglycerides?
The three types of fatty acids that compose triglycerides are saturated, monounsaturated and polyunsaturated fatty acids. From these three types of fatty acids come the three types of triglycerides, or fats; saturated, monounsaturated and polyunsaturated triglycerides.
What are the components of a triglyceride molecule quizlet?
What are the components of a triglyceride? A molecule of glycerol and 3 fatty acids.
What are the 4 main types of lipids?
The four main groups of lipids include:
- Fatty acids (saturated and unsaturated)
- Glycerides (glycerol-containing lipids)
- Nonglyceride lipids (sphingolipids, steroids, waxes)
- Complex lipids (lipoproteins, glycolipids)
What are the components of the triglyceride structure quizlet?
What are the components of a triglyceride? A molecule of glycerol and 3 fatty acids.
What are four functions of triglycerides quizlet?
Functions of triglycerides include energy storage, cushioning, thermal insulation, binding organs together and absorptions of some vitamins. Phospholipids take part in cell membrane structure, fat digestion and helps in the structure of myelin sheaths around neurons within the human body.
Which of these components is not found in a triglyceride molecule?
-Glycerol is part of a triglyceride. Sterols, glucose, and vitamins are not constituents of a triglyceride molecule.
What is a triglyceride quizlet?
Triglycerides. long term energy storage molecules formed during condensation synthesis between 3 fatty acids and one molecule of glycerol.
What are 4 examples of lipids?
Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein. Lipids are not soluble in water as they are non-polar, but are thus soluble in non-polar solvents such as chloroform.
What are the four classes of lipids and what is an example of each?
Lipids are a class of macromolecules that are nonpolar and hydrophobic in nature. Major types include fats and oils, waxes, phospholipids, and steroids. Fats are a stored form of energy and are also known as triacylglycerols or triglycerides. Fats are made up of fatty acids and either glycerol or sphingosine.
What is the structure of triglycerides quizlet?
What is the structure of a triglyceride? One glycerol molecule joined to three fatty acid molecules by three ester bonds.
What are 3 functions of triglycerides?
Triglycerides are necessary for certain bodily functions, but high levels of them can lead to health problems.
- Characteristics. Triglycerides are the most common lipid found in the body. …
- Energy Storage. …
- Health Impact. …
- Healthy Levels. …

How is triglyceride formed?
Triacylglycerols are formed by linking fatty acids with an ester linkage to three alcohol groups in glycerol. Triacylglycerols are the form in which fat energy is stored in adipose tissue. Triacylglycerols are sometimes referred to as triglycerides.
Which of these components is not found in A triglyceride molecule?
-Glycerol is part of a triglyceride. Sterols, glucose, and vitamins are not constituents of a triglyceride molecule.
What is a triglyceride composed of quizlet?

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.
What are the components of A triglyceride quizlet?
What are the components of a triglyceride? A molecule of glycerol and 3 fatty acids.
What is the structure of A triglyceride quizlet?
What is the structure of a triglyceride? One glycerol molecule joined to three fatty acid molecules by three ester bonds.
What are the 4 main functions of lipids?
The Functions of Lipids in the Body
- Storing Energy. The excess energy from the food we eat is digested and incorporated into adipose tissue, or fatty tissue. …
- Regulating and Signaling. …
- Insulating and Protecting. …
- Aiding Digestion and Increasing Bioavailability.
What are the four types of lipids and their functions?
Functions of Lipids
- Storage of energy for long-term use (e.g. triglycerides)
- Hormonal roles (e.g. steroids such as oestrogen and testosterone)
- Insulation – both thermal (triglycerides) and electrical (sphingolipids)
- Protection of internal organs (e.g. triglycerides and waxes)
What are the 4 main lipids?
Major types include fats and oils, waxes, phospholipids, and steroids.
How is A triglyceride molecule formed?
Triglycerides and phospholipids are two groups of lipid. Triglycerides are formed by the condensation of one molecule of glycerol and three molecules of fatty acid. A condensation reaction between glycerol and a fatty acid (RCOOH) forms an ester bond.
