sucrose correct answer: glucose + fructose with a glycosidic bond simple monosaccharide correct answer: formula: (CH2O)n -simplest carbohydrates -have an aldehyde or ketone group sugars with a aldehyde have a prefix aldo- sugars with a ketone group have a prefix keto- -if a ketose, the ketone group is always at carbon 2- this decreases the amount of isomers that could form -made up of chiral carbons- allowing the sugars to form different isomers, leading to structural diversity (aldos...

MCAT Biochemistry UPDATED ACTUAL Questions and CORRECT Answers Amino Acids - CORRECT ANSWER- - Found in proteins - amino group, carboxylic acid, hydrogen atom, and R group attached to a central alpha carbon - chiral (L) except glycine - (S) configuaration except cysteine - join via peptide bonds Nonpolar, nonaromatic AA - CORRECT ANSWER- glycine

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...

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 ...

What are the linear polysaccharides? - ACCURATE ANSWERS amylose, cellulose What are the branched polysaccharides? - ACCURATE ANSWERS glycogen and starch How do you calculate the amount of stereoisomers in a sugar? - ACCURATE ANSWERS n chiral centers= 2^n stereoisomers What denotes a D sugar from an L sugar in the linear conformation? - ACCURATE ANSWERS D: last OH group on right L: last OH group on left What are epimers? - ACCURATE ANSWERS stereoisomers that differ only in configurat...
