What chemical elements are found in all proteins?

Answer 1

Protein is composed of amino acids, which are in turn made up of mostly carbon, hydrogen, oxygen, and nitrogen.

A few amino acids also contain sulfur: both Cysteine and Methionine. Thus, proteins containing these amino acids would be made up of very small amounts of sulfur, in addition to the more common elements listed above.

The five chemical elements of protein are ,

1.) sulfur

2.) carbon

3.) hydrogen

4.) oxygen

5.) nitrogen

Answer 2

Proteins are made up of amino acids (molecules containing an amino group, a carboxylic acid group and a side-chain that varies between different amino acids). The key elements of an amino acid are carbon (C), hydrogen (H), oxygen (O) and nitrogen (N).

Nitogen, Oxygen, Hydrogen, Sulfur, Carbon

Carbon

Hydrogen

Oxygen

Nitrogen

And a variable group (Can be a carbon, hydrogen, or sometimes a sulfur)

Answer 3

Excluding trace elements, the primary constituents of proteins are:

• Carbon
• Hydrogen
• Nitrogen
• Oxygen
• Sulphur

Answer 4

The simple proteins contain carbon, hydrogen, nitrogen and oxygen but conjugated proteins also contain phosphorus.

Answer 5

The chemical elements found in all proteins are carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. These elements make up the amino acids that are the building blocks of proteins.

Answer 6

Hydrogen, Oxygen, Carbon and Nitrogen.

Answer 7

Proteins contain C, H, O, N.
