Document Summary

The boyer text deines biochemistry as the study of life at the molecular level . Look at the bigger picture (what does it mean to the paient) Biochemistry examines the chemistry of living organisms. Carbon, hydrogen, oxygen, nitrogen are the main elements. Caion = posiive; anion = negaive: protons and neutrons are in the nucleus, electrons move so fast that there is cloud forming, atomic number = top let; atomic weight = botom (# of protons and neutrons) Carbon is the atom involved in all organic molecules. Carbon can make 4 bonds (can go diferent direcions) The more electronegaive = draws negaive to it (more posiive core) Regards to the periodic table more electronegaive is on the top right. Donaion of electron from one element to another (see picture on the right) Proteins are made up of amino acids (memorize) Amino acids all have a similar structure, with diferent side chains.
