(d) 'f' carbon of glucose and 'f ' carbon of fructose.

 

Insulin is a globular proteins.

Ionisation enthalpy increases in a period. Z dominates over screening effect (s) in a period as Z_eff. increases.

Histidine is an essential amino acid

Lactose is a disaccharide which is formed by forming C? -C? glycosidic linkage between D-galactose and D- glucose.
Lactose - (Hydrolysis)-> D - galactose + D - glucose
