Document Summary

The central dogma is dna --> rna --> proteins. Deoxyribose is bonded with bas in a glycosidic bond. Between the beta of the sugar carbon one and the base. Atp = common source of lots of energy. The mono, di and tri just depends on the number of phosphates attached. Each red line is a high energy bond. Good leaving group can stabilize negative charge. Other biological molecules also have the same core structure as purines. Remember you can make adenine by heating up lots of cyanic acid. Guanine has lots of hydrogen bond donors and acceptors. Thymine is really just uracil with a methyl on the first carbon. Cytosine * exam* know the four forms. Bond is single bond so it has rotation. Mostly more anti than syn, but depends on if it in a string of molecules. Less h bonds = less energy to break. Blue means it is attached to phosphate there.
