Biological Molecules Flashcards
What are monomers and 4 examples?
Monomers are the smaller unites from which larger molecules are made. Monosaccharides,amino acids,nucleotides and glucose.
Condensation reaction?
joins two molecules together with the formation of a covalent bond and involves the elimination of a water molecule.
Hydrolysis reaction?
Breaks a covalent bond between two molecules and involves the use of a water molecule.
What are monosaccharides to carbohydrates and 3 examples?
Monosaccharides are the monomers from which larger carbohydrates are made. Glucose,galactose and fructose.
What are carbohydrates?
Molecules containing oxygen,carbon and hydrogen.
