Fatty acids are generally made using a complex called fatty acid synthase. This complex grabs a 3 carbon molecule in the first step (Malonyl-CoA) and adds to it a 2 carbon molecule (Acetyl-CoA). In this ajoinment, one carbon is lost as carbon dioxide, leaving a four carbon unit at the end of the first round. The fatty acid continues to grow by adding additional Malonyl-CoA molecules, sacrificing one carbon to join with the parent chain in each round. Therefore, the chain grows by two carbon units, giving us the plethora of even numbered fatty acids. Additional reactions are required to add odd numbered units to the chain, so the path of least resistance generates more even numbered chains than odd numbered chains in nature. When fatty acids are broken down by B-oxidation (most common), the chain degrades two carbons at a time.
Yes, fatty acids in the body can contain an odd number of carbon atoms. For example, omega-3 fatty acids such as alpha-linolenic acid have 18 carbon atoms, while omega-7 fatty acids like palmitoleic acid have 16 carbon atoms.
There aren't only even-numbered-carbon fatty acids. They just tend to generate glucose and an even numbered fatty acid. See link below.

How many carbon atoms do all fatty acids have?
They usually contain an even number of carbon atoms.
Which type of fatty acids has two or more carbon double bonds?
Fatty acids that contain carbon atoms linked by double or triple bonds are unsaturated. They do not have the maximum number of hydrogen atoms possible.
Are fatty acids with double bonds saturated or not?
Fatty acids with double bonds are unsaturated because they do not contain the maximum number of hydrogen atoms bound to the carbon chain. Saturated fatty acids have single bonds only.
How many carbon atoms are in carbonic acid?
There are three carbon atoms in carbonic acid (H2CO3), which consists of one carbon atom and three oxygen atoms.
Life on earth is said to be carbon based because organic molecules contain what kind of atoms?
Carbon atoms. Organic molecules, such as proteins, carbohydrates, lipids, and nucleic acids, all contain carbon atoms as their central structural element. This is why life on Earth is considered carbon-based.
How many carbon atoms do all fatty acids have?
They usually contain an even number of carbon atoms.
Do amino acids contain carbon?
Yes, amino acids are organic compounds that contain carbon, along with hydrogen, oxygen, and nitrogen atoms.
Do fatty acids have hydrogen?
Yes, fatty acids contain hydrogen atoms attached to carbon atoms in their hydrocarbon chain. The number and arrangement of these hydrogen atoms determine the type of fatty acid.
Which type of fatty acids has two or more carbon double bonds?
Fatty acids that contain carbon atoms linked by double or triple bonds are unsaturated. They do not have the maximum number of hydrogen atoms possible.
Are fatty acids with double bonds saturated or not?
Fatty acids with double bonds are unsaturated because they do not contain the maximum number of hydrogen atoms bound to the carbon chain. Saturated fatty acids have single bonds only.
What is the total number of carbons in one fatty acid?
Natural fatty acids contain 10 and onwards even no of carbon atoms.
Do fatty acids have nitrogen?
No, fatty acids do not contain nitrogen. They are composed of carbon, hydrogen, and oxygen atoms.
How many carbon atoms are in carbonic acid?
There are three carbon atoms in carbonic acid (H2CO3), which consists of one carbon atom and three oxygen atoms.

How many carbon atoms do hydrocarbons contain?
Hydrocarbons contain carbon and hydrogen atoms, with the number of carbon atoms varying depending on the specific hydrocarbon molecule. Typically, hydrocarbons can contain anywhere from one carbon atom in methane to hundreds or even thousands of carbon atoms in larger molecules.
What molecules are relatively complex molecules that contain a backbone of carbon atoms?
Organic molecules are relatively complex molecules that contain a backbone of carbon atoms. Examples include hydrocarbons, carbohydrates, proteins, lipids, and nucleic acids.
What kind of atoms do proteins contain?
All proteins contain carbon, oxygen, hydrogen and nitrogen. Some also contain sulphur in the amino acids Methionine and Cysteine.
