Functional Groups - Purdue University
• contain a C=O (“carbonyl”) group • note that in condensed structural formulas, the aldehyde group may be written as –CH=O or as –CHO I. Carboxylic Acids • contain a “carboxylic acid” group – a carbonyl (C=O) group bonded to a hydroxyl group at the carbonyl carbon atom

The Fermentation of Pyruvate - Purdue University
www.chem.purdue.eduundergo lactate fermentation. Two pyruvates are converted to two lactic acid molecules, which ionize to form lactate. In this process two NADH + H+ are converted to two NAD+. Our muscle cells can undergo this process when they are in oxygen debt. If enough oxygen is not present to undergo aerobic respiration, pyruvate will undergo lactic acid
