WitrynaAcidic and Basic Amino Acids. There are three amino acids that have basic side chains at neutral pH. These are arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base. Their pKa's are high enough that they tend to bind protons, gaining a positive charge in the process. WitrynaThe phospho-group carries a negative charge, which can influence confirmation or interactions. This chapter focuses on how this inert molecule can dramatically change the chromatin environment and, in turn, the survival or demise of an organism. ...
