Study Notes
Compounds and Elements
- Inorganic compounds do not have to contain both carbon and hydrogen.
- The chemical formula for hydrochloric acid is HCl.
- Oxygen is the third most abundant element in the human body after carbon and hydrogen.
Organic Compounds
- Organic compounds are synthesized for various purposes.
- Carbon-containing inorganic compounds include cyanides, cyanates, and carbonates.
Proteins
- Buffers help maintain pH homeostasis in the body.
- Fibrous proteins are strong, durable, and hydrophobic.
- Enzymatic reactions involve substrates binding to active sites.
- Globular proteins are highly reactive and hydrophilic.
Enzymes
- Without enzymes, the human body would be in a state of chaos.
- The main function of enzymes is to catalyze chemical reactions.
- The active site is responsible for substrate binding in enzymatic reactions.
Body Fluids
- Water is the major component of many lubricating fluids in the body.
- An adult's body weight is approximately 55-60% water.
- Water plays a crucial role in protecting organs from physical trauma.
- Water in synovial fluid helps absorb and dissipate heat without a significant temperature increase.
Mass and Weight
- An object's mass is a measure of its amount of matter, while its weight is the force exerted on it by gravity.
- An object weighs less on the moon compared to Earth due to the moon's lower gravity.
- Elements are different from compounds in that they consist of only one type of atom, whereas compounds consist of two or more different atoms.
- Elements must be obtained from the environment because the human body cannot synthesize them.
- Calcium (Ca) is essential for many bodily functions.
Other Key Concepts
- Glycoproteins and proteoglycans are produced from carbohydrates and proteins.
- The body uses proteins for energy when carbohydrate and fat intake is inadequate.
- Nucleotides can be assembled into nucleic acids.
- Nucleotides consist of a sugar molecule, a phosphate group, and a nitrogenous base.
- DNA (deoxyribonucleic acid) stores genetic information.
- Deoxyribose differs from ribose in that it lacks an oxygen atom on the 2' carbon.
