Study Notes
Differentiation of Organic and Inorganic Compounds
- Organic compounds contain carbon, while most inorganic compounds do not.
- Most organic compounds have carbon-hydrogen (C-H) bonds.
Examples of Organic and Inorganic Compounds
- Inorganic: Salt (NaCl), Water (H2O), Muriatic Acid (HCl)
- Organic: Sugar (C6H12O6), Linoleic Acid (C18H32O2), DNA, Alanine (C3H7NO2)
Importance of Carbon
- Carbon can bond to four other atoms due to its four valence electrons.
- This allows for the formation of a vast array of diverse molecules.
Types of Biomolecules
- Major categories: Carbohydrates, Proteins, Lipids, Nucleic Acids.
Polymers vs. Monomers
- Polymers are long molecules made of similar or identical building blocks (monomers) linked by covalent bonds.
Metabolism
- Metabolism consists of chemical reactions that convert food into energy.
- Catabolism: Breaks down biomolecules to release energy.
- Anabolism: Uses energy to synthesize complex biomolecules.
Major Biomolecules
- Carbohydrates: Monosaccharide building blocks; function as energy storage.
- Proteins: Composed of amino acids; essential for cell structure and function.
- Lipids: Made of glycerol and fatty acids; long-term energy storage and cell membrane structure.
- Nucleic Acids: Nucleotides; carry genetic information.
Carbohydrates
- Most abundant organic compounds; composed of carbon, hydrogen, oxygen in a 1:2:1 ratio.
- Monomer: Monosaccharides (e.g., glucose).
- Polymer: Polysaccharides (e.g., starch, cellulose, glycogen).
Types of Carbohydrates
- Monosaccharides: Single sugar units (e.g., glucose, fructose).
- Disaccharides: Two monosaccharides (e.g., maltose, lactose, sucrose).
- Polysaccharides: Long chains of monosaccharides (e.g., starch, cellulose, glycogen).
Formation of Disaccharides
- Condensation reaction links monosaccharides.
- Examples:
- Glucose + Glucose = Maltose
- Glucose + Galactose = Lactose
- Glucose + Fructose = Sucrose
Polysaccharides
- Formed from chains or branches of monosaccharides.
- Storage examples: Starch and Glycogen.
- Structural examples: Cellulose and Chitin.
Lipids
- Composed mainly of hydrocarbons; insoluble in water.
- Function: Long-term energy storage, insulation, cell membrane structure.
- Types include triglycerides, phospholipids, and steroids.
Types of Fatty Acids
- Saturated fats: Single bonds in the fatty acid chain; typically solid at room temperature.
- Unsaturated fats: One or more double bonds; commonly liquid (e.g., oils).
Types of Lipids
- Triglycerides: Glycerol + three fatty acids; primary energy source.
- Phospholipids: Essential for cell membrane structure.
- Steroids: Composed of fused carbon rings; regulate metabolism and immune response.
Cholesterol and Health
- Cholesterol can harden in blood vessels, contributing to atherosclerosis.
-
Lipoproteins:
- High-Density Lipoprotein (HDL): Good cholesterol, removes excess.
- Low-Density Lipoprotein (LDL): Bad cholesterol, associated with health risks.
Hormones Related to Lipids
- Sex Hormones: Testosterone, progesterone, estrogen; regulate reproductive functions.
- Adrenocorticoid Hormones: Include glucocorticoids and mineralocorticoids, important in stress response.
Summary Points
- Balance lipid intake; excess sugars are converted to fats.
- Awareness of the body’s fat storage is crucial, especially without physical activity.
