What is the formula for a monosaccharide? Use an example to describe how monosaccharides link to form disaccharides correct answer: (CH2O)*n, where n is the number of carbons and must be greater than 3 (e.g. glucose has 6 carbons, C6H12O6). Glucose and fructose are both monosaccharides, which link through a glycosidic bond to form sucrose, a disaccharide Name, classify and describe the two simplest monosaccharides (3 carbons) correct answer: Glyceraldehyde: Aldo-triose, aldehyde on one end ...

agarose and agar correct answer: polysaccharides used to run DNA gels and for microbial plates bacterial cell walls correct answer: contain polysaccharides in their peptidoglycan layer lectins correct answer: are proteins that bind to sugars protein glycolsylation correct answer: assists in folding and cellular recognition, e.g. ABO blood groups -ose correct answer: indicates a molecule is some kind of carb blood group antigens correct answer: glycoproteins containing differ...

Chem 219 Unit 3 Exam Questions With 100% Correct Answers Stereochemistry the study of the three-dimensional structure of molecules Stereoisomers Compounds with the same structural formula and connectivity but with a different 3D arrangement of the atoms in space. Enantiomers Stereoisomers that that are non-superimposable mirror images. Enantiomers have the same connectivity but different orientations (twist) of the four atoms or groups in 3D space. The two different forms of the chira...

Chapter 1 Carbon and Its Compounds CHECKPOINT PROBLEMS Practice Problem 1.1 a) S — 1s2 2s2 2p6 3s2 3p4 b) Cl — 1s2 2s2 2p6 3s2 3p5 c) Na+ — 1s2 2s2 2p6 1-2 Copyright © 2018 Nelson Education Limited Practice Problem 1.2 a) Count valence electrons. Build a basic bonding framework and account for electrons used. Add remaining electrons and check for formal charges. The molecule has a lone pair on the nitrogen. All other electrons are bonding electrons. b) Count valence electrons. Build a bas...
