L-Methionine
L-Methionine, an essential sulfur-containing amino acid, cannot be endogenously synthesized by humans and most monogastric animals (e.g., chickens, pigs) and must be obtained through dietary intake, nutritional supplements, or fortified products. Its sources are primarily categorized into natural dietary sources, industrial production (for additives), and specialized nutritional formulations. L-methionine sources range from natural foods (animal-derived as primary, plant-based as secondary) to industrial production (chemical synthesis and biofermentation for additives) and specialized nutritional products. The choice of source depends on dietary preferences, physiological needs, and application scenarios (human nutrition vs. animal feed).
