An electrocardiogram (EKG or ECG) is a test that checks for problems with the electrical activity of your heart. An EKG shows the heart 's electrical activity as line tracings on paper.The spikes and dips in the tracings are called waves.The heart is a muscular pump made up of four chambers.n electrocardiogram (EKG or ECG) is a test that checks for problems with the electrical activity of your heart.

This process is an important step in the synthesis of some non-essential amino acids (amino acids that can be synthesized de novo by the organism). The chirality of an amino acid is determined during transamination. This reaction uses the coenzyme PLP, and has been shown to be a kinetically perfect reaction.
As already noted, NAD(H) is the coenzyme or active form of vitamin B3. The chemistry of NAD(H) is some of the most complex in the human body. NAD(H) is necessary to oxidize (burn) all foodstuffs (fats, sugars, amino-acids) into ATP bioenergy. coenzyme is the active, or working form of a vitamin. NADH is the reduced (electron-energy rich) coenzyme form of vitamin B3, while NAD is the oxidized (burned) coenzyme form of B3.
