Which of the nutrients can be found in all organic compounds

Proteins, among the most complex of all organic compounds, are composed of amino acids (see Figure 2-4), which contain carbon, hydrogen, oxygen, and nitrogen atoms. Certain amino acids also have sulfur atoms, phosphorus, or other trace elements such as iron or copper.

Hello. This question is incomplete. The full question is:

"Which of the nutrients can be found in all organic compounds? a. nitrogen b. calcium c. carbon d. phosphorous"

Answer:

c. carbon

Explanation:

Currently, we can say that organic compounds are those formed by carbon, regardless of whether they were synthesized or not by living organisms.

All organic molecules have carbon atoms in addition to the vast majority of hydrogen atoms. However, other elements called heteroatoms, can be present chemically bonded between 2 carbon atoms in the chain, such as oxygen (O), nitrogen (N), sulfur (S), phosphorus (P) and halogens, chlorine (Cl), bromine (Br) and iodine (I). The bonding of carbon atoms with the elements mentioned above, forms structures called carbon chains, which are quite stable, and which can vary from 2 to hundreds of carbon atoms.
