What’s a monomer?
A single molecule that is a unit of a larger molecule
What’s a polymer?
A long chain of smaller repeating monomer units
What’s Starch?
A long chain polymer formed of @-glucose monomers
What’s sucrose?
A disaccharide result from @-Glucose and Fructose
What’s Lactose?
A disaccaride result formed from @-glucose + Galactose
What’s Maltose?
@-Glucose+@-Glucose
What’s Glucose?
A hexose sugar
How do u test for reducing sugars?
Add Benedict’s solution, if the sugars precipitate and colour change blue-orange they’re a reducing sugar, if no change they’re non-reducing
What’s a monosaccharide?
A single sugar monomer
What’s a disaccharide?
A sugar made up of two monosaccharides joined by a Glycosidic bond
What’s a polysaccharide?
A polymer made up of long chains of monosaccharides joined by glycosidic bonds
What is a triose sugar?
A sugar with 3 carbon atoms
What is a pentose sugar?
A sugar with 5 carbon atoms
What is ribose?
A pentose sugar that makes up RNA
What’s a hexose sugar?
A sugar with 6 carbon atoms
What’s an isomer?
A molecule that has the same chemical formula but different structures
What is a condensation reaction?
A reaction where a molecule of water is removed as a result of two molecules bonding
What is a Glycosidic bond?
A covalent bond formed between two monosaccharides in a condensation reaction
What’s Amylose?
An unbranched polymer made up of between 200-5000 glucose molecules
What’s Amylopectin?
A branched polymer of glucose molecules
What are lipids?
A large family of organic molecules
What’s a fatty acid?
An organic acid with a long hydrocarbon chain
What’s an Ester bond
A bond formed in a condensation reaction between the carboxyl group of a fatty acid and one of the hydroxyl groups of glycerol
What’s a Saturated fatty acid?
Each carbon joined to the one next to it in the hydrocarbon chain by a single covalent bond
