Study Notes

Organic Chemistry

  • Organic chemistry studies organic compounds.
  • All organic compounds contain carbon.
  • Many organic compounds come from living things.
  • Most naturally occurring compounds are organic.

Carbohydrates

  • Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen in a 1:2:1 ratio.
  • Sugars and starches are examples.
  • Living organisms use carbohydrates as an energy source and structural support.

Monosaccharides

  • Simplest carbohydrates (simple sugars).
  • Examples include glucose and fructose.

Disaccharides

  • Two monosaccharides covalently bonded together.
  • Examples include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose).

Polysaccharides

  • Large polymers composed of thousands of linked monosaccharides.
  • Examples include starch, cellulose and glycogen.
  • Starch: found in wheat, rice, corn, and potatoes; plants store glucose as starch.
  • Cellulose: structural support in plants.
  • Glycogen: animals store excess sugars as glycogen.

Lipids

  • Lipids include fats, oils, waxes, and steroids.
  • Generally composed of carbon, hydrogen, and oxygen, similar to carbohydrates but in different ratios.

Fats

  • Composed of glycerol and three fatty acids.
  • Used for energy storage and insulation.
  • Excess carbohydrates are converted to fats for storage.
  • Fatty acids are long chains of carbon atoms with an acid group at one end.
  • The structure of fatty acids determines the properties of the fat.
  • (Approximately 30 fatty acids in animals).

Other Lipids

  • Phospholipids: Lipids containing phosphorous (phosphate); major component of cell membranes.
  • Steroids: Composed of four linked carbon rings; examples include cholesterol and hormones that regulate bodily functions.
  • Waxes: Organic compounds composed of fatty acids and alcohols, often used for protection or waterproofing.

Proteins

  • Proteins are organic compounds composed of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur.
  • Essential components of living organisms (muscles, hair, and skin).
  • Proteins are polymers of amino acids.

Amino Acids

  • Building blocks of proteins.
  • Twenty different amino acids are used to make proteins.
  • Amino acids are composed of an amino group (-NH2), a carboxyl group (-COOH), and a side group that determines the amino acid's identity.
  • The bonds between amino groups form peptide bonds

Protein Functions

  • Movement: Actin and myosin in muscle fibers.
  • Structure: Collagen (connective tissue).
  • Control: Enzymes that speed up chemical reactions.
  • Transport: Hemoglobin (carries oxygen and carbon dioxide in the blood)
  • Storage: Casein in milk stores amino acids for developing offspring.
  • Regulation: Hormones that regulate growth, development, and metabolism
  • Defense: Antibodies of the immune system

Nucleic Acids

  • Large complex molecules composed of carbon, hydrogen, oxygen, nitrogen, and phosphorous (DNA and RNA).
  • Genetic material.
  • DNA (Deoxyribonucleic Acid): Stores genetic information in cells.
  • RNA (Ribonucleic Acid): Assists in protein synthesis.
