Daqu, as a starter of Chinese liquor fermentation, affects both saccharification and fermentation.However, it is still unclear how Daqu contributed to the simultaneous saccharification and fermentation process. Here, using Chinese light … Aldehydes participate in many reactions. From the industrial perspective, important reactions are (a) condensations, e.g., to prepare plasticizers and polyols, and (b) reduction to produce alcohols, especially "oxo-alcohols". From the biological perspective, the key reactions involve addition of nucleophiles to the formyl carbon in the formation of imines (oxidative deamination) and hemiacetals (structures of aldose sugars).
