Chapter 5 Study Guide Flashcards
How is so much diversity generated from a small number of monomeric ‘building blocks’ in specific classes of biological macromolecules?
Different types of monomers can combine in many configurations, causing a diverse group of macromolecules
What is the role of dehydration synthesis in forming polymers?
Dehydration synthesis puts two monomers together with an output of water.
What is the role of hydrolysis in breaking down polymers?
Hydrolysis breaks monomers apart with in input of water.
What is the monomer and polymer of Carbohydrates?
Monosaccharides and polysaccharides
How do you know when it is an alpha glucose vs a beta glucose?
The OH group on an alpha glucose is pointed down while the OH group on a beta glucose is pointed up.
When/where do glycosidic linkages form?
They form between monosaccharides after dehydration synthesis
What are the structural and functional characteristics of starch?
Alpha 1-4 glucose glycosidic linkages, stores energy (glucose) in plants
What are the structural and functional characteristics of Glycogen?
Alpha 1-4 and 1-6 glucose glycosidic linkages, stores energy (glucose) in animals stored in the liver and skeletal muscle cells
What are the different types of starch and how do you differentiate them?
Amylose and amylopectin. Amylose is linear while amylopectin is branched (1-6 bonds glucose)
What are the structural and functional characteristics of Cellulose?
Cellulose is a structural polysaccharide found in plants with beta glucose. Cellulose does not branch.
What are the structural and functional characteristics of Chitin?
A structural polymer found in animals exoskeletons formed with beta 1-4 bonds
What property unifies Lipids a diverse group of molecules?
What are the functions of fats and oils?
Insulation of organs, cushioning/protection of organs, and long-term energy storage
What are the structural components of glycerol?
3 hydroxyl groups (alcohol), 3 carbons, 5 hydrogens
What are the structural components of a fatty acid?
A carboxyl group and a methyl group, a long hydrocarbon chain. Saturated is a straight chain, unsaturated has a kink because of a double bond.
