Study Notes
Chemical Level of Organization
- Cellular organization is crucial in understanding anatomy and physiology.
- Familiarize with fundamental chemistry concepts to comprehend biological processes.
Common Elements in the Human Body
- Elements are the simplest form of matter with unique chemical properties.
- Each atom is made up of subatomic particles: neutrons (no charge), protons (positive charge).
Important Ions in the Human Body
- Ions play vital roles in physiological processes and cell signaling.
Chemical Bonding
- Covalent bonding involves the transfer of electrons between nonmetals.
- Polar covalent bonds involve unequal sharing of electrons, leading to asymmetric charge.
- Nonpolar covalent bonds involve equal sharing of electrons; molecules have symmetrical charge.
- Hydrogen bonds occur between polar molecules due to weak attractions.
Chemical Reactions
- Chemical reactions involve the formation or breaking of bonds.
- Reactants are substances that undergo reactions, while products are the resulting substances.
Types of Chemical Reactions
- Synthesis Reactions: Multiple reactants combine to form complex products (Anabolism in the body).
- Decomposition Reactions: Reactants break down into simpler products (Catabolism in digestion).
- Exchange Reactions: Involve both synthesis and decomposition processes.
Organic Compounds
- Carbohydrates are structured as CnH2nOn and include monosaccharides (glucose, fructose), disaccharides (sucrose), and polysaccharides (glycogen, starch).
- Monosaccharides serve as primary energy sources for cells, while polysaccharides act as energy storage.
Lipids
- Lipids are nonpolar compounds insoluble in water; they include fats, phospholipids, eicosanoids, and steroids.
- Fats are key energy storage molecules and serve as insulation.
- Phospholipids are fundamental components of cell membranes.
- Eicosanoids function in regulatory roles, especially in tissue response to injury.
- Cholesterol is a significant steroid involved in membrane structure and hormone synthesis.
