Carbohydrates Flashcards
What is the key functions of carbohydrates?
Give instant energy
What is the monomer of carbohydrates?
Monosaccharides
What is a good exemple of a monosaccharide and what would be is chemical equation
Glucose: c6H12o6
What are to polymers of carbohydrates?
-disaccharides
-polysaccharides
What is a disaccharide carbohydrate?
It is a hydroxyl group combine to release water molecules and form covalent bond
Give an exemple of a disaccharides and explain why it is a disaccharide?
Lactose b/c it is formed of glucose+galactose
What is a polysaccharides?
-long chain of monosaccharides linked by glycosidic bonds
Where are located the carbohydrates?
Exterior of the plasma membrane attach to a protein (glycoproteins) or a lipid (glycolipids)
What is the metabolic importance of monosaccharides?
-primary energy sources for cells
-involved in glycolysis
What is the structural important of monosaccharides?
-building blocks for larger carbohydrates
What is the metabolic importances of disaccharides?
-serve as quick energy sources
-broke down monosaccharides for absorption
What is the structural importance of disaccharide?
They play a role in energy storage and transport
What is the metabolic importance of a polysaccharides?
-Serve as energy reserves
What are the 5 properties of water?
1)High heat capacity
2)High evaporation capacity
3)Ice is less dense than liquid water
4)It a solvent
5)cohesive and adhesive
Water molecules are polar or non-polar molecules?
Polar
What is the bond in the H2O molecule?
Polar covalent bond
What is the name of the bond between two molecules of water?
Hydrogen bond
Why is water longer to heat up and cool down than other liquids?
B/c they require a bigger energy to break a form of H bonds
What happens to water molecules when the pH=7?
They ionise spontaneously
What is the principle of catabolism?
Process of breaking down complex molecules to form simpler one
What is the process of anabolism?
Mechanism that take smaller units to create bigger structures
What are isomers?
Isomers are molecule with the same chemical formula but different chemicals properties
