Week 2 Assignment The four macromolecules are carbohydrates, proteins, lipids, and nucleic acids.

Living things are composed of organic and inorganic compounds, hydrocarbons molecules form when both carbon and hydrogen combine as one,

“All living things are composed of intricate systems of inorganic and organic compounds. There are many kinds of organic compounds that are found in nature, such as hydrocarbons. Hydrocarbons are the molecules that are formed when carbon and hydrogen combine” (WiseGeek).

Carbohydrates, are composed of three different components. The components are carbon, hydrogen, and oxygen, “a carbohydrate is composed of carbon, hydrogen, and oxygen in a ratio

You contain more than 2 million different proteins. Some provide structural support, and others function in physiological processes” (Ireland 72). There are also four levels of complexity to protein. The primary structure, an arrangement of amino acids in a protein, “the linear arrangement of amino acids in a protein and the location of covalent linkages such as disulfide bonds between amino acids” (Bowen). The secondary structure is where the coiling and folding within a protein are happening. The tertiary structure is the third structure where it becomes a three dimensional structure of protein, “the final three-dimensional structure of a protein, which results from a large number of non-covalent interactions between amino acids” (Bowen). The quaternary structure is the last one, where non covalent interactions bind, and become a larger

The nucleic acids allow genetic information to transfer from one generation to the following. DNA contains genetic information, it also builds protein to control the physiological processes, “It contains the hereditary (genetic) information of the cell. DNA encodes the information needed to build proteins, to regulate physiological processes” (Ireland 76).
