All proteins contain carbon, hydrogen, oxygen and nitrogen. Most of them also contain sulfur, which is found in the standard amino acid residues cysteine and methionine (any given protein might not contain either of these, though it would be unusual).
carbon hydrogen oxygen and nitrogen
a protein contains carbon hydrogen oxygen nitrogen and sulfur.
No. Water is composed of hydrogen and oxygen. Proteins are composed of carbon, nitrogen, hydrogen, and oxygen.
Four items that make a protein are carbon, hydrogen, nitrogen and oxygen. These are the four items that make up an amino acid. Protein is made up of amino acids.
Oxygen, hydrogen, carbon and nitrogen
Proteins are the nutrient that contains nitrogen, carbon, oxygen, and hydrogen. Proteins are made up of amino acids, which are the building blocks of proteins and contain these four elements.
Protein, Carbon, and nitrogen. I'm 100% sure about that!
protein
Proteins contain carbon, hydrogen, oxygen, and nitrogen.
Chemically, proteins have carbon, oxygen, hydrogen, and nitrogen. The nitrogen is a definite key.
Hydrogen (H), Oxygen (O), Nitrogen (N) and Carbon (C) The last one is Carbon, not Protein. Protein isn't an element, it is an organic compound. For example Glucose and Fructose are C6H12O6
