sugar L configuation

Study These Flashcards

A

bottom OH on the left

sugar D configuration

bottom OH on the right

anomers

alpha and beta forms of haworth projection

alpha haworth

lowest OH faces down

beta haworth

lowest OH faces up

5 mem ring

furanose

6 mem ring

pyranose

for D sugars, CH2OH is pointed...

up on C4 or C5

bottom OH on fischer becomes what on haworth?

ether oxygen H goes to the alpha/beta OH

carbonyl O on fischer becomes what on haworth?

O of the OH

ribose classification

aldopentose

glucose classification

aldohexose

galactose classification

aldohexose

fructose classification

ketohexose

ribulose classifcation

ketopentose

mannose classification

aldohexose

disaccharide nomenclature

sugar-yl-(#C --> #C)-sugar

O linked glycosylation

on serione, threonine

N linked glycosylation

on asparagine

application of glycosylation

drug masking

2 types of polysaccharide

hetero homo

examples of polysaccharides

starch cellulose peptidoglycan chitin glycogen

present on reducing sugars

hemiacetal group OH on same C attached to ether O

special about reducing sugars

can be trapped in fischer projection form

3 tests for reducing sugars

Benedicts test Fehling's test Tollens test

intensity of reducing sugar positive given by.....

number of hemiacetals exposed
