BIOL 251 Lecture Notes - Lecture 1: Galactose, Disaccharide, Starch
Document Summary
Include carbs, nucleic acids, proteins and lipids. Disaccharides: glucose + glucose= maltose, glucose + fructose= sucrose, glucose+ galactose= lactose. Dehydration synthesis- the removal of water to create a larger molecule. Hydrolysis- add water to a disaccharide to create two monosaccharides. Glycogen- animal starch, used to store carbohydrates, stored in cells of muscle and liver. Cellulose- plant starch, forms a stiff molecule in the cell wall, gives support to the plant. Animals cannot break it down because they don"t have cellulose, the enzyme necessary for catabolism. Contain an amine group (nh2), carboxyl (acid) group (cooh), r group (20 different) Peptide bond is formed through dehydration synthesis. Functions of proteins include: structure: connective tissue (hair, nails, bone, regulatory: some hormones, enzymes, motion: cilia, microtubules, flagella, muscles, protection: anitbodies, transport: membrane transporters within the blood.
