The single free 1-OH group is called the “reducing end” of the molecule and is noted by the letter R in Figure 5-18. In contrast, numerous “non-reducing ends” are present (i.e., free 4-OH and 6-OH groups) at the terminals of the outermost chains. dansani pro good minimenuet

Webb29 okt. 2024 · Liquefaction is the process of dispersing starch molecules in water and partially hydrolyzing them. Once the starch is liquefied, it can expose more non-reducing ends that are affected by alpha-amylase. Liquefaction can be carried out with an acid or an alpha-amylase. There are many reports on the research of liquefaction process of starch. WebbTubers of potato (Solanum tuberosum L.), one of the most important crops, are a prominent example for an efficient production of storage starch.
