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.

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.
