Carbohydrates

Question 1

Monosaccharides

Answer 1

Simplest carb
have hydroxel groups on all carbons except carbonyl carbon

Question 2

Aldoses

Answer 2

Monosaccharides that containan aldehyde

Question 3

Ketoses

Answer 3

Monosaccharides that contain a ketone

Question 4

Classifying monosaccharides

Answer 4

Number of carbons
3= triose
4= tetrose
5= pentose

Question 5

Difference between a D sugar and L sugar?

Answer 5

L: OH is on Left
D: OH is on right

Question 6

How to tell if it’s alpha or beta?

Answer 6

Alpha: OH is is on bottom
Beta: OH is on top

Question 7

Glucose vs Galactos haworth

Answer 7

The OH group is different
Look at carbon 4 to tell difference
In glucose OH group is on bottom
In galactos OH group is on top
Both aldohexos
Monosaccharides

Question 8

Fructose

Answer 8

A ketohexose
Looks like a pyramid
Monosaccharide

Question 9

Reduction in monosaccharides

Answer 9

Converts an aldehyde group to alcohol producing sugar alcohols
