This study investigated the formation of bisdemethoxycurcumin in fresh-cut yam. The effects of storage temperature on the metabolites, expressions of critical genes, and activities of enzymes involved in the bisdemethoxycurcumin pathway in fresh-cut yam were studied by HPLC, qRT-PCR and com. kits. Storage at 25°C increased the contents of bisdemethoxycurcumin and its main intermediates compared to 4°C. It also greatly improved the activities of key enzymes in the phenylpropanoid pathway, including phenylalanine ammonia lyase (PAL), cinnamic acid-4-hydroxylase (C4H), and 4-coumarate-CoA ligase (4CL), and enhanced the gene expressions of PAL, C4H, 4CL, hydroxycinnamoyltransferase, and O-methyltransferase. These changes decreased the content of phenylalanine and increased the contents of p-coumaric acid, cinnamic acid, p-coumaroyl-CoA, and feruloyl-CoA. Importantly, storage at 25°C enhanced the expression of curcumin synthase, whereas it had no effect on diketide-CoA synthase, curcumin synthase 1, curcumin synthase 2, and curcumin synthase 3, in agreement with the observed increase in bisdemethoxycurcumin content in fresh-cut yam compared to 4°C. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Recommanded Product: 33171-05-0).
Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: 33171-05-0
