Webb23 mars 2024 · Dear student,Reducing sugars are the sugars which have free OH group. Amylose is a linear poly-D-glucose in which the monosaccharides are connected by alpha 1, 4 linkages. One end of the amylose has free OH group so it is known as reducing end. So amylose is a reducing sugar. Thanks and regards WebbNatural substrates such as starch and glycogen are broken down into glucose and maltose. Pure, crystalline β-amylase preparation consists of four isoenzymes with different isoelectric points. The enzyme polymerizes very rapidly through the sulfhydryl groups in the absence of reducing agents. p-Chloromercuribenzoate inhibits the polymerization and …

Ans: The molecule is branched, with each branch ending in a nonreducing end. (See Fig. 7-14c, p. 5.)
WebbReducing sugars are the sugars which have free OH group. Starch is formed by a-1,4 linkages between two glucose unit which is broken down during its digestion. It exists in two forms known as amylose and amylopectin. Amylose is a linear poly-D-glucose in which the monosaccharides are connected by alpha 1, 4 linkages. WebbVerified questions. health.
