Do hydrocarbons only contain carbon and hydrogen?
Hydrocarbons. The simplest Organic compounds are made up of only Carbon and Hydrogen atoms only. Compounds of Carbon and Hydrogen only are called Hydrocarbons.
How many carbon atoms does a fat molecule have?
Fatty acids have a long chain of hydrocarbons with a carboxyl group attached and may have 4-36 carbons; however, most of them have 12-18. In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom.
How many carbon atoms are in a protein?
Three such basic amino acids, each containing six carbon atoms, occur in proteins.
Do fats contain carbon, hydrogen and oxygen?

Why fatty acids contain even number of carbon atoms?
The synthesis of even-chained fatty acid synthesis is done by assembling acetyl-CoA precursors. Because the segments are each two carbons in length the resulting fatty acid has an even number of carbon atoms in it.
Are fats polar or nonpolar?
However, in fatty acids, the non-polar hydrocarbon chain gives the molecule a non-polar character. Saturated fats have a chain like structure which allows them to stack very well forming a solid at room temperature.
What two elements are found in fatty acid chains?
Fatty acids are constructed from the chemical elements carbon, oxygen and hydrogen. Fatty acids can be divided into a carboxylic acid head group–hence fatty acid–linked to a long chain of carbon atoms.
What types of products are formed during fatty acids with an even number of carbon atoms and odd number of carbon atoms?
During beta oxidation of fatty acids, carbons are removed from the fatty acid chain two at a time. So when a fatty acid is composed of an even number of carbons (as most are) 4 carbons will be left at the end. This will be cleaved into two separate 2 carbon molecules – two acetyl-CoA molecules.
How many fatty acids contain multiple double bonds between carbon and carbon?
Carbon-carbon double bonds (unsaturations) are found in naturally occurring fatty acids. There may be one double bond or many, up to six in important fatty acids. Fatty acids with one double bond are the most prevalent in the human body, comprising about half of the total.
What term describes fatty acids that contain no carbon to carbon double bonds?
Thus, saturated fatty acids contain no carbon-to-carbon double bonds, monounsaturated fatty acids contain one carbon-to-carbon double bond, and polyunsaturated fatty acids contain two or more carbon-to-carbon double bonds.
Are hydrocarbons that have single bonds between carbon atoms?
Hydrocarbons having single bond between carbon atoms are called alkane.
Which of the following alkanes contains two carbons?
To name an alkane, first identify the longest chain of carbon atoms in its structure. A two-carbon chain is called ethane; a three-carbon chain, propane; and a four-carbon chain, butane. Longer chains are named as follows: pentane (five-carbon chain), hexane (6), heptane (7), octane (8), nonane (9), and decane (10).
When two carbon atoms are joined by a double bond the carbons and atoms bound to them form which of the following structures?
When two carbon atoms are joined together by two bonding pairs of electrons, a double bond is formed. A double bond forces the two carbon atoms and attached groups into a rigid, planar structure. As a result, a molecule such as CHCl=CHCl can exist in two nonidentical forms called geometric isomers.
What are lipids atoms?
Lipids are composed of carbon, hydrogen and oxygen atoms, and in some cases contain phosphorus, nitrogen, sulfur and other elements.
Which of the following is most found in protein molecule?
Proteins are found in all living organisms and are composed of molecules called amino acids. Each amino acid contains four elements they are hydrogen, oxygen, nitrogen and carbon and in certain cases may also contain sulfur.
How many oxygen atoms are present in each fatty acid?
In a fat molecule, a fatty acid is attached to each of the three oxygen atoms in the –OH groups of the glycerol molecule with a covalent bond ([Figure 6]).
What atoms make up fatty acids?
Generally, a fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end. It is that carboxyl group that makes it an acid (carboxylic acid).
What can carbon atoms form?
A carbon atom forms four bonds in stable organic compounds such as ethane, ethene (ethylene), and ethyne (acetylene). Each carbon atom in ethane forms four single bonds, one to each of three hydrogen atoms and one to the neighboring carbon atom.
Which of the following is formed by protein?
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
