Since many centuries, whey has been used for the treatment of numerous ailments. Briefly elaborate upon the scientific relevance of it.
Show Hint
Whey proteins are classified into three types: Whey Concentrate (contains some fat/lactose), Whey Isolate (highly purified, over $90%$ protein), and Whey Hydrolysate (pre-digested for rapid absorption).

Solution and Explanation
Step 1: What is Whey?
Whey is the liquid bi-product of cheese production, separated from the curd during milk coagulation. For centuries, it has been used as a traditional folk remedy for various digestive and inflammatory conditions.
Step 2: High Nutritional Quality
Whey is rich in highly digestible proteins, including $\beta$-lactoglobulin, $\alpha$-lactalbumin, bovine serum albumin, and immunoglobulins. These proteins contain a complete profile of essential amino acids, particularly branched-chain amino acids (BCAAs) like leucine, which stimulate muscle protein synthesis and recovery.
Step 3: Immunomodulatory Properties (Glutathione Synthesis)
Whey proteins contain high concentrations of the amino acid cysteine. Cysteine is the rate-limiting precursor for the synthesis of glutathione (GSH), the body's primary intracellular antioxidant. Higher glutathione levels boost immune function, protect cells from oxidative stress, and assist in liver detoxification, explaining whey's effectiveness in aiding recovery.
Step 4: Bioactive Peptides
Enzymatic digestion of whey proteins releases short, bioactive peptides (such as lactokinins). These peptides exhibit several therapeutic benefits:
1. Antihistaminic & Antihypertensive: Inhibit ACE enzymes to help lower blood pressure.
2. Antimicrobial: Whey contains lactoferrin, an iron-binding protein that inhibits pathogenic bacterial growth.
Final Answer: Whey's therapeutic value is based on its rich concentration of immunoglobulins and cysteine, which are crucial for synthesizing glutathione, the master antioxidant that boosts immune function. It also contains bioactive peptides that lower blood pressure and combat microbes.
