There are more than four elements in proteins : Carbon, hydrogen, oxygen, nitrogen, sulphur and selenium being the main six. It is not clear where you got the number 4 from and therefore which four you are asking about.
The chemical formula of the compound shows the ratio of the atoms of elements in a compound. This must not be confused with the ratio of their masses.
The ratio depends on the compound.
no one cares
carbohydrates, lipids, proteins and nucleic acids
K:H:P:O = 1:2:1:4
8 to 4
There are four elements. They are these C,H,O,N
They are made from amino acids.
Four elements can be found. They are carbon.hydrogen,oxygen and nitrogen
Carbon, Hydrogen, Oxygen and Nitrogen

H = Hydrogen, C = Carbon, O = Oxygen, and N = Nitrogen. These are the Symbols for these four "proteinaceous" Elements.
Trace Elements Oxygen Carbon Hydrogen Nitrogen These four elements make up 96% of the human body.
The first four elements are oxygen, carbon, hydrogen and nitrogen.They form water, proteins, enzymes, etc.
what consists of elements combined in a specific ratio?
The chemical formula of the compound shows the ratio of the atoms of elements in a compound. This must not be confused with the ratio of their masses.
Proteins are not elements; they are very complex organic compounds.
