WebSep 15, 2024 · The three most abundant polysaccharides are starch, glycogen, and cellulose. These three are referred to as homopolymers because each yields only one type of monosaccharide (glucose) after complete hydrolysis. Heteropolymers may contain sugar acids, amino sugars, or noncarbohydrate substances in addition to monosaccharides. … WebThe optimal reaction conditions for acid hydrolysis of regular corn starch under an electric field were 5 cycles of 10 s each. Under those conditions a relatively high crystallinity together with a high gelatinization temperature range of the treated starches are achieved.
