|
Carbonyl functional group |
C=O , their presence provides sugars with an array of reactive groups. |
|
|
Hydroxyl Functional Group |
-OH |
|
|
Carbohydrates consist of which functional groups |
Carbonyl and hydroxyl functional groups. |
|
|
How to number carbons in a monosaccharide. |
Numbered consecutively, starting with the end nearest the carbonyl group. |
|
|
Aldose |
An aldose is a monosaccharide (a simple sugar) that contains only one aldehyde (−CH=O) group per molecule |
|
|
Simple sugars differ in three respects |
Location of carbonyl group, number of carbon atoms present, and spatial arrangement of their atoms, particularly relative position of hydroxyl groups. |
|
|
How to monosaccharides link? |
Condensation reactions between 2 hydroxyl groups, resulting in a covalent interaction called a glycosidic linkage. |
|
|
A-1,4-glycosidic linkage means? |
Above plane, carbonyl group one connected to another molecule's carbonyl group 4. |
|
|
Starch |
a -1,4-glycosidic between glucose molecules into a helix. Two polysaccharides; unbranched amylosr and branched amylopectin (1-6-glycosidic linkages) at ratio of 1 branch: 30 monomers. |
|
|
Glycogen |
Animal energy storage in liver & muscles. Polymers of a-1,6-glycosidic linkaged between a-glucose. Nearly identical to branched form if starch except rate of 1 branch: 10 monomers. |
|
|
Cellulose |
Plant structural polysaccharide. B-1,4-glycosidic linkages. |
