β-Casomorphin, human, is primarily studied for its potential effects on the human body, particularly in the context of digestion and neurological responses. It is believed to interact with opioid receptors, which may influence pain perception and mood. Researchers are exploring its role in conditions like autism and schizophrenia, as well as its impact on gastrointestinal functions, such as motility and secretion. Additionally, it is being investigated for its possible involvement in immune system modulation and its effects on infant development, particularly in relation to breastfeeding. However, its exact mechanisms and clinical applications remain under active research.
