Lactic acid Lactic acid is an organic compound with the formula CH3CH(OH)CO2H. In its solid state, it is white and water-soluble. In its liquid state, it is clear. It is produced both naturally and synthetically. With a hydroxyl group adjacent to the carboxyl group, lactic acid is classified as an alpha-hydroxy acid (AHA). In the form of its conjugate base called lactate, it plays a role in several biochemical processes. In solution, it can ionize a proton from the carboxyl group, producing the lactate ion CH. 3CH(OH)CO−. 2. Compared to acetic acid, its pKa is 1 unit less, meaning lactic acid deprotonates ten times more easily than acetic acid does.

The oxidized form of vitamin C, dehydroascorbic acid, regulates neuronal energy metabolism Abstract. Vitamin C is an essential factor for neuronal function and survival, existing in two redox states, ascorbic acid (AA), and its oxidized form, dehydroascorbic acid (DHA). Here, we show uptake of both AA and DHA by primary cultures of rat brain cortical neurons.e proposed that the ascorbic acid (AA) taken up by neurons is rapidly oxidized to dehydroascorbic acid (DHA), which inhibits glycolysis and activates the pentose phosphate pathway (PPP), consequently producing NADPH, a critical antioxidant in the recycling of oxidized glutathione (GSSG).

- Brønsted Acids and Bases in Nonaqueous Solutions Typical Brønsted Acids and Their Conjugate Bases For more than 300 years, substances that behaved like vinegar have been classified as acids, while those that have properties like the ash from a wood fire have been called alkalies or bases. The name acid comes from the Latin acidus, which means sour, and refers to the sharp odor and sour taste of many acids.
