Inorganic vs Organic•Non-living •Produced by living•Do not contain thingscarbon (exceptions) •All contain carbon•Needed for life •Important organic•Plants organize compoundsinorganic compounds –Carbohydratesinto organic –Lipids•H2O, O2, CO2 –Proteins•Minerals, nitrates –Nucleic acids
What is the big deal about carbon??Carbon is very versatileIt can form 4 covalent bonds
Where does all of the carbon for living things come from?Organic Molecule
Carbohydrates Needed for short term energy storage (cell fuel) and structural support Made of C, H, O (1:2:1) Building blocks (monomers) are simple sugars C6H12O6 Big– Carbos – made by dehydration synthesis of two simple sugars
Dehydration Synthesis Inorder for monomers to bond, a water is released in the bonding process In the bonding of monomers – water is added and it is called hydrolysis
3 Types of Carbohydrates Monosaccharides – simple sugars Disaccharides – double sugars Polysaccharides – many sugars
Monosaccharides – simple sugars C6H12O6 Manufactured by green plants Burned in Cellular glucose Respiration 3 examples fructose galactose
Glucose, Fructose, and Galatose Are ISOMERS - same formula C6H12O6 Different Molecular arrangment.
