  • D sugars are mirror images of L sugars
  • Carbohydrates are chiral molecules with carbon atoms carrying four different groups
  • Glyceraldehyde exists as a pair of enantiomers
  • Epimers differ at only one chiral center
  • Diastereomers are stereoisomers that are not exact mirror images
  • Hemiacetals and hemiketals are formed from the reaction between aldehydes or ketones and alcohols
  • Monosaccharides can form cyclic hemiacetals
  • Anomers are two possible diastereomers that may form during the cyclization reaction
  • Mutarotation is the interconversion of alpha and beta anomers in solution
  • Haworth projections are used to represent cyclic sugars
  • Monosaccharides can undergo oxidation, reduction, phosphate ester formation, amino sugar formation, and glycoside formation
  • Reducing sugars have the ability to reduce silver and copper ions.
  • Reducing sugars have aldehyde groups, hydroxyketone groups, or cyclic hemiacetal groups.
  • Reduction tests such as the Benedict, Barfoed, and Fehling tests are used to detect reducing sugars.
  • The Tollens test is based on the formation of a silver mirror.
  • The Barfoed test can distinguish between reducing monosaccharides and reducing disaccharides.
  • Hydrolysis is the process of breaking a chemical bond between two molecules using a water molecule.
  • Phosphate esters of monosaccharides play important roles in carbohydrate metabolism.
  • Amino sugars have one hydroxyl group replaced with an amino group.
  • Glycoside formation involves the reaction of hemiacetals with alcohols to form acetals.
  • Disaccharides are formed by the condensation of two monosaccharides through glycosidic bonds.
  • Common disaccharides include maltose, sucrose, and lactose.
  • Lactose intolerance is a condition where individuals lack the enzyme lactase needed to hydrolyze lactose.
  • Cellobiose is a reducing disaccharide found in cellulose.
  • Invert sugar is formed by the hydrolysis of sucrose and is commonly used in food processing.
  • Artificial sweeteners like aspartame and sucralose are noncarbohydrate sweeteners.
  • Water is the solvent for biochemical reactions
  • Heat capacity is the amount of energy needed to raise the temperature of a substance
  • Hydrolysis is the breaking of a chemical bond between two molecules using a water molecule
  • Oligosaccharides are commonly found in onions, cabbage, broccoli, and wheat
  • Antigens in the ABO blood group are polysaccharides
  • Starch is the chief caloric distributor in the diet and the reserve carbohydrates for plants
  • Amylose is a long, unbranched chain polymer of glucose units joined by (α1→4) glycosidic bonds
  • Amylopectin is a branched chain polymer of glucose units joined primarily by (α1→4) glycosidic bonds and occasionally by (α1→6) glycosidic bonds
  • Glycogen is the glucose storage molecule of animals, stored in granules in liver and skeletal muscle cells
  • Cellulose is a fibrous carbohydrate found in plants and is the structural component of the plant's cell wall
  • Chitin is a polymer of N-acetyl-D-glucosamine and gives rigidity to the exoskeletons of arthropods
  • Dextrans are bacterial and yeast polysaccharides made up of (α1→6)-linked poly-D-glucose
  • Carageenan is a hydrocolloid extracted from red algae and widely used in the food industry
  • Peptidoglycan is a network of cross-linked carbohydrate chains and peptides that constitutes the cell walls of bacteria
