Study Notes

Carbohydrates

  • Found in fruits, sugar cane, milk, cereals, potatoes, bread, and noodles
  • Ribose and deoxyribose are building blocks for nucleic acids (RNA and DNA)
  • Cellulose is a dietary fiber that helps prevent constipation
  • Excess carbohydrates are stored as glycogen in skeletal muscles and the liver, or as fat
  • Carbohydrates provide energy

Lipids

  • Found in meat, butter, egg yolk, corn oil, olive oil, and margarine
  • Phospholipids are a major component of cell membranes
  • Cholesterol is a raw material for producing certain hormones (sex hormones)
  • Lipids are involved in the absorption, transport, and storage of fat-soluble vitamins (e.g., vitamins A and D)
  • Excess lipids are stored as adipose tissue (subcutaneous fat or visceral fat)
  • Lipids act as heat insulators and shock absorbers for internal organs
  • A diet rich in lipids may lead to diseases like coronary heart disease and obesity.
