Question

The linkage between the two monosaccharide units in lactose is (A) C1 of β-D-glucose and C4 of β-D-galactose (B) C1 of β-D-galactose and C4 of β-D-glucose (C) C1 of α-D-galactose and C4 of β-D-glucose (D) C1 of β-D-galactose and C4 of α-D-glucose

Tardigrade Admin · Accepted Answer

C-1 of β-D-galactose and C-4 of β-D-glucose. In lactose, β-D-gaiactose is joined to C-4 of β-D-glucose.

Q. The linkage between the two monosaccharide units in lactose is

$C_{1}$ of $β - D -$ glucose and $C_{4}$ of $β - D -$ galactose

$C_{1}$ of $β - D -$ galactose and $C_{4}$ of $β - D -$ glucose

$C_{1}$ of $α - D -$ galactose and $C_{4}$ of $β - D -$ glucose

$C_{1}$ of $β - D -$ galactose and $C_{4}$ of $α - D -$ glucose

$C_{1}$ of $α - D -$ glucose and $C_{4}$ of $β - D$ -glucose

C-1 of $β$ -D-galactose and C-4 of $β$ -D-glucose. In lactose, $β$ -D-gaiactose is joined to C-4 of $β$ -D-glucose.
