Trace amounts of fluorine (as fluoride ...
8 sie 2023 · Although dietary proteins contain 4 kcal of energy per gram, they are considered a less efficient energy source than lipids or carbohydrates. Rather, the most important function of dietary proteins is to supply amino acids, which provide nitrogen, hydrocarbon skeletons, and sulfur.
24 lut 2023 · OpenStax. Learning Objectives. By the end of this section, you will be able to: Compare and contrast inorganic and organic compounds. Identify the properties of water that make it essential to life. Explain the role of salts in body functioning. Distinguish between acids and bases, and explain their role in pH.
Identify the building blocks of nucleic acids, and the roles of DNA, RNA, and ATP in human functioning. Organic compounds typically consist of groups of carbon atoms covalently bonded to hydrogen, usually oxygen, and often other elements as well.
Except for dietary fiber, all dietary carbohydrates are considered nonessential. Every other major class of nutrients contains multiple essential compounds. For example, there are nine essential amino acids, at least two essential fatty acids, and many essential vitamins and minerals.
Inorganic Nutrients. Inorganic nutrients include both water and minerals. Inorganic nutrients do not contain both carbon and hydrogen, and they are not created or destroyed. Minerals can’t be destroyed, so they are the ash left when a food is burned to completion.
