Lecture Number 4 - Structure And Functions Of Macromolecules Flashcards
Backbone of molecules
Carbon based molecules
Carbons distinctive properties
Four valence electrons, can form four covalent bonds with other moelcules or atoms
Functional groups of carbon
Componets that attatch itself to carbon to give it distinct properties
Polymer
Composed of monomers
Monomers
Single unit
How do monomers create polymers
Dehydration reaction happens when two or more monomers join together because of the loss of water
Enzymes
Macromolecules that speed up dehydration
Polymores to monomers
Hydrolysis break down polymers into monomers
Macromolecules
Large molecules compsed of thousand of covalent bonded atoms
4 groups of macromolecules
Protein
Carb
Lipids
Nucleic acids
Carbohydrates
Include sugars and polymers of sugars
Polyssaccharides
Polymoers composed of many sugar building blocks
Linked toether b glycosidic bonds formed by condensation
Monosaccharides
Fuel fr ceels and raw material for building molecules
Structural isomers
Identical moelcular formulas but diff structure
Sucorse
Glucose and fructose
Lactose
Glucose and galactose
Maltose
Glucose and glucose
Roles of polysaccharides
To store energy
Structural polysaccharides
Cellulose
Indigetsibkle polysaccharide made by reapting units of glucose
Humans lack enzyme to digest cellulose
