Two of these molecules make up one molecule of maltose.
Hemoglobin can react with this molecule to form a protein known as Hb A1C ("H B A one C"). PEP carboxy-kinase is required for a pathway used to produce this molecule in the liver. Levels of this molecule are reduced in the blood by activation of the transporter GLUT4 to help cells absorb it. Two of these molecules make up one molecule of maltose. This molecule is the most common substrate of hexokinase, which phosphorylates it to form G6P. Blood levels of this molecule are usually reduced by insulin, so levels of this molecule can grow unchecked in diabetes mellitus. For 10 points, name this six-carbon sugar that is broken down in glycolysis.
