Document Summary
Study of biochemistry emerged when someone produced urea in a lab setting when it was thought previously that it can only be produced in the human body. Then they thought that maybe the same or a similar chemical process to the one produced in lab, was occurring in the body. Organisms are remarkably similar at the molecular level. Four major classes of biomolecules: proteins [monomer: amino acid, nucleic acids [monomer: nucleotide, carbohydrates (polysaccharides) [monomer: sugar, lipids [monomer: fatty acid] Bonds are tetrahedral (bonds are 109. 5 away from each other) Double bond in c makes molecule at since a double bond is rigid: proteins. Carbohydrates (ie. sugars) are usually of the empirical formula (ch2o)n. Sugars with 5 or more carbons can form rings. Ringed sugars can form chains: linear and/or branched. Can classify aldehydes and ketones as aldose and ketone (*) Diverse group of biomolecules that are insoluble in water.
