Glycogen is
a polymer of β-D-glucose units
a structural polysaccharide
structurally very much similar to amylopectin
structurally similar to amylopectin but extensively branched
D.
structurally similar to amylopectin but extensively branched
Glycogen (C6H10O5)n is condensation polymer of α-D-glucose. Glycogen 1s also called animal starch because it structure is similar to that of amylopectin. Amylopectin chains consist of about 20-25 D-glucose urnts but glycogen chains are much shorter i.e they consist ofabout 10-14 glucose units. In other words glycogen is more highly branched than amylopectin.
The glycosidic linkage present in sucrose is between
C-1 of -β- glucose and C-4 of α- glucose
C-1 of α- glucose and C-4 of β-fructose
C-1 of α- glucose and C-4 of α- glucose
C-1 of α- glucose and C-2 of β-fructose
Cheilosis and digestive disorder are due to the deficiency of
thiamine
ascorbic acid
riboflavin
pyridoxine
Hormones are secreted by ductless glands of human body. Iodine containing hormone is
Adrenoline
Thyroxine
Testosterone
Insulin
Sucrose is not a reducing sugar since
it contains no free aldehyde or keto group adjacent to, -CHOH group
it is built up of a fructose unit
it is optically active
it is chemically stable
The statement that is not correct is
Aldose or ketose sugars in alkailne medium do not isomerise
Carbohydrates are optically active
Pentaacetate of glucose does not react with hydroxylamine
Lactose has glycosidc linkage between C4 of glucose and C1 of galactose unit.
