Lipids are a family of very important organic molecules that contain a lot of carbon like proteins and carbohydrates.
Lipids come in two main types that are found in the body: triglycerides and phospholipids.
The detailed structure of a triglyceride normally looks like this with one molecule and three parts coming off at the end.
The distinguishing feature of a phospholipid is this phosphate group lying on the end.
Triglycerides are more used as a source of energy and can be found in a variety of foods such as oily foods, butter, and certain fats.
Oils found in various plants are also sources of triglycerides.
Phospholipids are used more for a structural role in building up the cell membranes and the membranes that surround the cell act as a barrier to the outside world.
The main component making up this layer is called a phospholipid.
Lipids are mainly composed of the elements carbon, hydrogen, and there is some oxygen thrown in there as well.
The triglyceride is composed of two components: glycerol and fatty acids, which join together to form the triglyceride.
Condensation reactions join things together, forming water and an ester bond.
In order to make the triglyceride, three condensation reactions are needed, forming three molecules of water.
Every time an ester bond is formed, water is removed.
The end product of a condensation reaction is a triglyceride with three ester bonds.
The fatty acids in a triglyceride molecule are organic acids with a carboxyl group or "COOH" group on one end and that end is joined to a hydrocarbon tail.
Condensation reactions form water because one oxygen atom and two hydrogen atoms are removed from the glycerol and fatty acid.
The ester bond is the covalent bond formed by a condensation reaction between the oh group of a carboxylic acid and the oh group of an alcohol.
The total glycerol molecule is represented on the left, and three individual fatty acids, also known as carboxylic acids, are represented on the right.
The reaction itself forms the water because one oxygen atom and two hydrogen atoms are removed from the glycerol and fatty acid.
The glycerol in a triglyceride molecule is an organic alcohol with three hydroxyl groups or "OH" groups on its side.
The carboxyl group in a triglyceride molecule always has a carbon joins to one oxygen and then another oxygen and an "OH" so it's "COOH".
The carboxylic acid in a triglyceride molecule is acidic and it's called a carboxylic acid.
The hydrocarbon tail in a triglyceride molecule can be represented by the letter "r".
A triglyceride molecule is formed from one molecule of a compound called glycerol and it's connected to three fatty acids.
The hydrocarbon tail in a triglyceride molecule is made purely of carbons and hydrogens joined up.
Triglycerides are used to provide an energy source.
Hydrocarbon chains, which are often found in these lipid structures, are composed of carbon and hydrogen.
Triglycerides are formed by connecting one glycerol molecule to three fatty acids, which are formed by three ester bonds.
The formation of triglycerides involves a condensation reaction, while their breakdown involves a hydrolysis reaction.
In three hydrolysis reactions, triglycerides can be broken down into glycerol and three fatty acids, which are the components that make them up.
In order to break three bonds in a triglyceride, three molecules of water are needed, as three oxygen atoms and six hydrogen atoms are added to the triglyceride.
Hydrolysis can be broken down into two parts: lysis means to break, and hydro means water, indicating that water is needed to break these things apart.
The overall reaction of breaking down triglycerides into glycerol and three fatty acids is known as hydrolysis.
Condensation is the process of forming triglycerides, while hydrolysis is the process of breaking them down.
The process of breaking down triglycerides into glycerol and three fatty acids requires the input of three molecules of water and it breaks three ester bonds.
The components of triglycerides are glycerol and three fatty acids.
At the end of a lipid structure, different groups can be found depending on the different lipids.
Lipids are large complex molecules known as macromolecules.
Macromolecules are not polymers, as each of the units is not a monomer.
Lipids can be described as non-polar molecules and will not dissolve in water.
