Intro to Carbohydrates - Student developed note
Use p. 29-33 to create your own intro notes to CARBOHYDRATES. Read all of the statement below before starting
your note. These statements are formatted so you are able to effectively develop and organize your note. After your
note is written answer the textbook question to further develop your understanding.
Part A: INTRODUCTION
Below are 5 introductory points about what a carbohydrate is and its uses from p. 29
To distinguish between monosaccharides you look for...
PART B: LINEAR CHAINS vs. RING FORMATIONS OF CARBOHYDRATES
Below are diagrams of the saccharides in LINEAR CHAIN FORM. Chains exist only when saccharides are NOT in
solution (i.e. dry, crystal-like as you’d see them in a sugar bowl at home)
Note the location of functional groups.
a) triose sugar glyceraldhyde
c) isomer of hexose sugar
galactose
b) isomers of a hexose sugar
glucose
d) isomer of hexose sugar
fructose
In solution, like when they are traveling in our blood, or mixed into food, linear chain carbohydrates tend to into their
RING STRUCTURE
Glucose has two important isomers in its ring state:
a) alpha- Glucose
1-3
b) beta-glucose
Note: to see the difference, see the location of the hydroxyl group on C 1 changes.
An ogliosaccharide is a
A glysolidic linkage is:
PART C: Important types of olgliosaccharides and and polysaccharides
Each molecule has a distinct glycosidic linkage that dictates its function. In the space below you will see examples of
these molecules with their glycosidic linkages labeled and their functions/ uses outlined
a) animal: disaccharides
maltose
sucrose
b) animal energy storage: polysaccharides
glycogen
c) plant storage: Starch
amylose
(chain of alpha glucose)
amylopectin
(branched chains of alpha glucose)
Now that you have your notes made and answer the questions p. 37 # 1-7
2-3
d) plant structure: Cellulose
polymer of beta glucose
e) insect structure: Chitin
N-acetylglucosamine
