glycoconjugate - Answers A compound containing a carbohydrate component bound covalently to a
protein or lipid, forming a glycoprotein or glycolipid.
carbohydrate - Answers A polyhydroxy aldehyde or ketone, or substance that yields such a compound
on hydrolysis. Many carbohydrates have the empirical formula (CH₂O) ₙ; some also contain nitrogen,
phosphorus, or sulfur.
monosaccharide - Answers A carbohydrate consisting of a single sugar unit.
oligosaccharide - Answers Several monosaccharide groups joined by glycosidic bonds.
disaccharide - Answers A carbohydrate consisting of two covalently joined monosaccharide units.
polysaccharide - Answers A linear or branched polymer of monosaccharide units linked by glycosidic
bonds.
aldose - Answers A simple sugar in which the carbonyl carbon atom is an aldehyde; that is, the carbonyl
carbon is at one end of the carbon chain.
ketose - Answers A simple monosaccharide in which the carbonyl group is a ketone.
Fischer projection forumlas - Answers A method for representing molecules that shows the
configuration of groups around chiral centers; also known as projection formulas.
epimers - Answers Two stereoisomers differing in configuration at one asymmetric center in a
compound having two or more asymmetric centers.
hemiacetal - Answers A compound that results from the addition of an alcohol to an aldehyde.
hemiketal - Answers A compound that results from the addition of an alcohol to a ketone.
anomers - Answers Two stereoisomers of a given sugar that differ only in the configuration about the
carbonyl (anomeric) carbon atom)
anomeric carbon - Answers The carbon atom in a sugar at the new chiral center formed when a sugar
cyclizes to form a hemiacetal. This is the carbonyl carbon of aldehydes and ketones.
pyranose - Answers A simple sugar containing the six-membered pyran ring.
furanose - Answers A simple sugar containing the five-membered furan ring.
Haworth perspective formulas - Answers A method for representing cyclic chemical structures so as to
define the configuration of each substituent group; commonly used for representing sugars.
