Document Summary
Chapter 1: scope of biochemistry -- the chemistry of life at the molecular level. Chapter 2: aqueous solutions -- the matrix of life. Chapter 6: techniques of protein and nucleic acid purification. Chapter 7: covalent structures of proteins and amino acids. Chapter 9: protein folding, dynamics, and structural evolution. Biochemistry: the chemistry of life at the molecular level. Eukaryotes: have a membrane enclosed nucleus, can be unicellular to multicellular. Recent studies have found that although bacteria do not have membrane-bound organelles, they have some membrane-less organelles that function as those in eukaryotes. Bound by a cell membrane: a lipid bilayer that controls passage of molecules in/out of the cell. Cell walls make them more resilient -- antibiotic resistance. Cytoplasm: contains one chromosome, rna, enzymes, and ribosomes. 10 to 100 um, so a thousand to a million times the volume of a typical prokaryotic cell! Prokaryotes: grow fast and survive in extremely harsh environments.
