CARBOHYDRATES AND LIPIDS

Notes

CARBOHYDRATES AND LIPIDS: Cytoplasm and Hydrophilicity • All cells contain cytoplasm, which is primarily composed of water All molecules inside the cell must be hydrophilic to function properly. • The bloodstream is water-based . It appears red because of floating red blood cells. Nutrients float between those cells and must be hydrophilic, otherwise, they carpot be transported • Lipids that are transported need to be in hydrophilic forms. • Some particles are amphipathic (having both hydrophilic and hydrophobic parts) Cholesterol is an example--it sticks to the walls of arteries • Whether a substance is hydrophilic or hydrophobic determines its role and mobility in biological Systems • Hydrophobic substances tend to stick and cannot be easily washed away by water Carbohydrates Energy Role and Glucose • Carbohydrates provide energy through glucose • Glucose enters the cellular respiration process, producing ATP, the energy cumency used for all cellular functions • Glucose is considered the most essential carbohydrate in life • It is produced via photosynthesis and is foundational in the food chain: plants - herbivores - camivores. • Glucose is the first brick" of organic molecule...
