Description

Application

• Gut microbiota-bile acid crosstalk and metabolic fatty liver in spotted seabass (Lateolabrax maculatus): The role of a cholesterol, taurine and glycine supplement.: This study investigates the use of glycine in dietary supplements to modulate gut microbiota and bile acid metabolism, which significantly impacts liver health and fat metabolism in marine species, providing insights into nutritional strategies for aquaculture (Song et al., 2024).
