Study Notes

Macromolecules Overview

  • Macromolecules are essential biological molecules, including carbohydrates, proteins, lipids, and nucleic acids.
  • Each macromolecule serves specific functions critical for life.

Carbohydrates

  • Glucose: Provides immediate energy; also acts as short-term energy storage in plants.
  • Starch: Long-term energy storage for plants; a polysaccharide made of many glucose units.
  • Glycogen: Long-term energy storage for animals; highly branched structure.
  • Cellulose: Forms the cell wall in plant cells; provides structural support.
  • Monosaccharide: The simplest form of carbohydrates, consisting of single sugar units; includes glucose and fructose.
  • Polysaccharide: Comprises many monosaccharides; includes starch, glycogen, and cellulose.

Proteins

  • Amino Acids: Monomers of proteins; essential for various biological functions.
  • Enzymes: Proteins that significantly speed up chemical reactions by lowering activation energy.
  • Protein Sources: Includes food items like beef jerky, cheese, eggs, and bacon, which are rich in proteins.
  • Functions: Involved in muscle growth, immune response, and structural components (like nails and hair).

Lipids

  • Fats: Includes saturated fats (animal sources) and unsaturated fats (e.g., sesame oil).
  • Phospholipids: Key components of cell membranes; consist of glycerol combined with fatty acids.
  • Cholesterol: A steroid that contributes to cellular membrane structure.
  • Steroids: Hormones that include sex hormones; play roles in metabolism and immune response.
  • Energy Storage: Lipids provide long-term energy storage, especially important during periods of food scarcity.

Nucleic Acids

  • DNA: The genetic material responsible for hereditary information; encodes instructions for building proteins.
  • RNA: Plays a role in protein synthesis; involved in translating genetic information to synthesize amino acids.
  • Nucleotides: The monomers of nucleic acids; consist of a sugar, phosphate group, and nitrogenous base.

Energy and Nutritional Needs

  • Quick energy needs after abstaining from food can be met with monosaccharides.
  • Building muscles and growing strong nails or hair requires proteins.
  • For prolonged energy requirements or preparation for hibernation, lipids serve as key sources.
  • To prepare for physical activities such as races, polysaccharides offer necessary fuel via stored energy.

Food Sources by Category

  • Carbohydrates: Found in table sugars, popcorn, noodles, and fruits like oranges and cranberries.
  • Proteins: Available in eggs, beef, bacon, and plant sources like soybeans and legumes.
  • Lipids: Present in oils, butter, and fatty foods.

Classification

  • Monosaccharides and Disaccharides: Simple sugars that provide quick energy.
  • Polysaccharides: Complex sugars that offer longer-lasting energy.
  • Proteins and Amino Acids: Vital for growth, repair, and overall body function.
  • Lipids: Important for energy storage and cellular structure.
