![]() This water is contained both within the cells and between the cells that make up tissues and organs. ![]() Organic compounds are covered later in the chapter.Īs much as 70 percent of an adult’s body weight is water. The following section examines the four groups of inorganic compounds essential to life: water, salts, acids, and bases. You will soon discover how these two elements combine in the foods you eat, in the compounds that make up your body structure, and in the chemicals that fuel your functioning. ![]() Recall that carbon and hydrogen are the second and third most abundant elements in your body. Organic compounds are synthesized via covalent bonds within living organisms, including the human body. An organic compound is a substance that contains both carbon and hydrogen.Carbon dioxide (CO 2) is one of the few examples. In contrast, only a handful of inorganic compounds contain carbon atoms. A great many inorganic compounds do contain hydrogen atoms, such as water (H 2O) and the hydrochloric acid (HCl) produced by your stomach. An inorganic compound is a substance that does not contain both carbon and hydrogen.In general, these compounds are either inorganic or organic. This section of the chapter narrows the focus to the chemistry of human life that is, the compounds important for the body’s structure and function. The concepts you have learned so far in this chapter govern all forms of matter, and would work as a foundation for geology as well as biology. Discuss the role of buffers in helping the body maintain pH homeostasis.Distinguish between acids and bases, and explain their role in pH.Explain the role of salts in body functioning.Identify the properties of water that make it essential to life.Compare and contrast inorganic and organic compounds.By the end of this section, you will be able to:
