biological molecules- monomers, polymers and carbs

define monomer and give examples

smaller units that join to form larger molecules. e.g: monosaccharides (glucose, fructose) + amino acids and nucleotides

define polymer and give examples

molecules formed when many monomers join tg. e.g: polysaccharides, proteins and dna/rna

what happens in a condensation reaction

chemical bond forms between 2 molecules, molecule of water formed

what happens in a hydrolysis reaction

water molecule used to break bond between 2 molecules

3 hexose monosaccharides

glucose , fructose, galactose

name bond formed when monosaccharides react

1,4 or 1,6 glycosidic bond. 2 monomers is one chemical bond = disaccharide, many monomers is many chemical bonds = polysaccharide

name 3 disaccharides and how they form

condensation reaction forms glycosidic bond between 2 monosaccharides. maltose is glucose and glucose. sucrose is glucose and fructose. lactose is glucose and galactose. molecular formula is C12H22O11
