Document Summary

Carbon based, produced by or comprising living organisms, beware: minerals are not of biological origin (ex. Caco3: have not been acted upon by living organisms, functional groups. Organic compounds: a group of specific atoms held together in a specific 3d pattern or shape when attached to another molecule, convert special physical properties to that organic molecule, dominate chemical properties of biomolecules c. i. Methyl group is hydrophobic: amino groups act as bases. Isomers: structural, geometric a. typically associated with double bond and arrangement around double bond, enantiomers, mirror images (just like right and left hands) Biomolecules: 4 main types, carbohydrates (subunits monosaccharides, proteins (subunits amino acids) c, nucleic acids (subunits nucleotides) lipids (subunits glycerol and fatty acids, characteristics, macromolecule polymers (except lipids) a. i. Very large: dehydration reactions link monomers, hydrolysis reactions break polymers d. Ingested as food, broken down through digestion, and absorbed. ***sucrose glucose + fructose e. ii. 1: polysaccharides plants store up sucrose for later use f. i.
