 The Chemical Decline in Energy

It is the destiny of wine to be drunk, and it is the destiny of glucose to be oxidized. But it was not oxidized immediately: its drinker kept it in his liver for more than a week, well curled up and tranquil, as a reserve aliment for a sudden effort; an effort that he was forced to make the following Sunday, pursuing a bolting horse. Farewell to the hexagonal structure: in the space of a few instants the skein was unwound and became glucose again, and this was dragged by the bloodstream all t...

 Lactate, Lactose, and Lactase

Lactate Lactate is a negatively charged molecule formed from a compound called lactic acid. Some bacteria make lactate when they metabolize sugars. Humans also produce lactate as a byproduct of metabolism, though only under certain conditions. Specifically, says Dr. Gary Thibodeau in his book "Anatomy and Physiology," you make lactate when your cells process sugars for energy in the absence of oxygen, such as when you're engaging in a hard sprint or power efforts during exercise. Lact...

Lactose and Lactase apparently have no relation to Lactate. Lactose is a sugar in milk, Lactase is an enzyme babies use to digest milk, and Lactate is a byproduct of our muscles expending energy, which is itself a source of energy.
