The gigabyte (/ËÉ¡ÉªÉ¡ÉbaÉªt/ GIG-É-byt or /ËdÊÉªÉ¡ÉbaÉªt/) is a multiple of the unit byte for digital information. The prefix giga means 109 in the International System of Units (SI). Therefore, one gigabyte is 1000000000bytes. The unit symbol for the gigabyte is GB. This definition is used in all contexts of science, engineering, business, and many areas of computing, including hard drive, solid state drive, and tape capacities, as well as data transmission speeds.
The regulation of K+ distribution between the intracellular and extracellular space is referred to as internal K+ balance. The most important factors regulating this movement under normal conditions are insulin and catecholamines (1).
The effect of the substituent on the conjugate acid or base influences the Ka (equilibrium constant) of the ionization, which in turn influences the pKa or acid strength. For basic compounds, the acid strength of the conjugate acid can then be related to the pKb, or base strength. (Note: Always draw the ionization scheme to express Ka with the acid on the left and the base on the right).
