Quizplus · Accepted Answer

Glucose is a source of energy for the body and can be used to synthesize pentoses, which are important for DNA and RNA synthesis. Tyrosine is used to produce thyroid hormone, which regulates metabolism. Cholesterol is a precursor for the synthesis of cortisol, which plays a role in stress response. Glycine is an amino acid that is used in the synthesis of adenine, a component of DNA and RNA. However, glucose is not a precursor for arachidonic acid, which is a fatty acid that is important for the synthesis of inflammatory molecules.
