Over 97% of dietary protein is absorbed as amino acids in the intestine, highlighting the critical need for tight metabolic control. The regulation of amino acids is a complex, multi-layered process that ensures cellular homeostasis, coordinates protein synthesis and degradation, and allows the body to adapt to fluctuating nutritional conditions.

Over 50% of the body's total glucose is stored in the form of glycogen, a highly branched polysaccharide found mainly in the liver and muscles. This critical biological process provides a compact, safe, and readily accessible form of energy, addressing significant challenges that would arise from storing glucose in its free, monomeric form.

In a healthy adult weighing around 70 kg, approximately 4 grams of glucose, a simple sugar, is consistently circulating in the bloodstream. This small but critical amount is the body's lifeblood for energy, and its regulation is essential for metabolic homeostasis.
