1C, 2 H and 1 O would be CH2O and that is the formula for formaldehyde (H2C=O). This isn't really a biomolecule, however.
Carbon, hydrogen, and oxygen
no. Carbohydrates contain carbon, hydrogen, and oxygen.
hydrogen, carbon, oxygen
No.Hydrocarbon molecules contain hydrogen and carbon atoms.It is carbohydrate molecules that contain hydrogen, carbon, and oxygen atoms.
Carbohydrates fall into the general formula Cx(H2O)y, each molecule containing carbon, hydrogen, and oxygen atoms.
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).
None. Hydrogen, oxygen, and carbon are all elements. Elements do not contain other elements.
Nucleotides which make up DNA contain carbon, hydrogen, phosphorus and oxygen.
all organic molecules contain carbon atomsCarbon, hydrogen and oxygen
No. They contain oxygen and carbon. Hence the carbonate.
No. Sugars are composed of carbon, hydrogen, and oxygen, but not nitrogen.
Normally only Carbon, Hydrogen and Oxygen They are effectively hydrocarbon chains held together by ester bonds ("oxygen joints")
