PHSL 310 Lecture Notes - Lecture 4: Redox, Ionic Bonding, Hydrogen Bond
Document Summary
Ions: formed when strong electronegative can capture electrons from other atoms. 2. 2 non-covalent bonds: noncovalent bonds: depend on shared electrons on attractive forces between atoms with opposite charge, are weak, break easily. Is a solvent, dissolves solutes: can form weak interactions, separates ions, forms bonds with organic polar groups solubility, amphoteric: serves as acid and base. A classification of biological molecules by function: macromolecules: contain carbon, form structure/carry out activities of cells that are huge. 2. 5 four types of biological molecules carbs, lipids, proteins, nucleic acids: carbohydrates: include simple sugars (monosaccharides) and sugar building blocks, function: chemical energy, building blocks, formula (ch2o) n where n= 3-7, sugars classified according to carbons trioses, tetroses, etc. The structure of simple sugars: each sugar backbone of carbon, each carbon linked to hydroxyl group (carbonyl are exceptions, ketose: carbonyl group located internally, aldose: forms aldehyde at end of chain.
