Study Notes

Organic Compounds

  • Contain carbon and are produced naturally by organisms.
  • Integral to various biological processes and structures.

Inorganic Compounds

  • Generally do not contain carbon, e.g., water, salts, minerals.

Hydrocarbons

  • Simplicity defines them; composed only of hydrogen and carbon.
  • Serve as foundational molecules in organic chemistry.

Substituted Hydrocarbons

  • Hydrocarbons modified by elements other than hydrogen or carbon.

Common Elements in Organic Compounds

  • Six primary elements: carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur.

Biological Macromolecules

  • Complex organic molecules with distinct functions in living organisms.

Monomers and Polymers

  • Monomers are single unit building blocks.
  • Polymers are long chains formed from monomers.

Major Groups of Biological Macromolecules

  • Four main categories: carbohydrates, proteins, lipids, nucleic acids.

Carbohydrates

  • Composed of carbon, hydrogen, and oxygen.
  • Primarily serve as energy sources; serve structural roles in some cases.

Monosaccharides

  • Simplest form of carbohydrates; single-ringed sugars ending in -ose.

Isomers

  • Molecules with identical molecular formulas but different structures, e.g., glucose vs. fructose (C6H12O6).

Disaccharides

  • Formed through dehydration synthesis; consist of two ring structures.

Dehydration Synthesis

  • Process of bonding monomers by removing water.

Hydrolysis

  • The chemical reaction that breaks bonds between monomers by adding water.

Polysaccharides

  • Formed from chains of monosaccharides; complex carbohydrates.

Types of Polysaccharides

  • Include starch, cellulose, glycogen, and chitin.

Starch

  • Storage form of excess sugar in plants, found in roots, stems, and leaves; uses alpha 1-4 linkages.

Cellulose

  • Structural polysaccharide in plant cell walls; features beta 1-4 linkages, forming sheets through hydrogen bonding.

Glycogen

  • Animal equivalent of starch for sugar storage in the liver, with a highly branched structure.

Chitin

  • Tough structural polysaccharide found in the exoskeletons of invertebrates, also contains nitrogen.

Proteins

  • Composed of carbon, hydrogen, oxygen, nitrogen, and sulfur.
  • Functionally diverse: structural (hair, nails), reactive (hormones, antibodies, enzymes).

Amino Acids

  • Building blocks of proteins; 20 different types exist.

Functional Groups in Amino Acids

  • Carboxyl group (COOH) and amine group vary among different amino acids.

Polypeptides

  • Chains of amino acids; referred to as proteins when they achieve specific structures, ranging from 50 to 100,000 amino acids.

Peptide Bond

  • The bond that links amino acids in a polypeptide chain.

Types of Proteins

  • Fibrous proteins: structural components (e.g., keratin, collagen).
  • Globular proteins: involved in chemical reactivity (e.g., enzymes, hormones).

Enzymes

  • Organic catalysts that accelerate chemical reactions without alteration.
  • Lower activation energy and exhibit specificity based on their unique shapes.

Substrate

  • The specific target on which an enzyme acts.

Lock and Key Theory

  • Enzymes interact with particular substrates that fit their specific 3D shapes.

Activated Complex

  • A temporary structure formed when an enzyme binds to its substrate.

Denaturation

  • Loss of a protein's normal shape due to environmental changes (pH, temperature), rendering it unable to function.

Lipids

  • Composed of carbon, hydrogen, and oxygen; play critical roles in cellular structure and energy storage.
