Sometimes these are also considered members of the immediate family, depending on an individual's specific relationship. In most societies, the family is the principal institution for the socialization of children.
Nucleic acids also typically contain phosphorous, and nitrogen plays an important structural role in nucleic acids and proteins. The proteins, being made up a diverse set of amino acids, have, in addition to carbon, hydrogen, oxygen, and nitrogen, the elements sulfur and selenium. It is incredible the complex array of macromolecules that can be built starting with these simple elements. To unlock this lesson you must be a Study.com Member.
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. Figure 2-4 The structure and chemistry of amino acids.
