Characterizing the composition, metabolism and physiological functions of the fatty liver in Rana omeimontis tadpoles

Frontiers in Zoology, 2019
Background Fat storage is required for the life cycle of many organisms. The primary fat depot for most vertebrates is white adipose tissue. However, in primitive vertebrates (e.g., agnathan group and elasmobranchs), the liver is usually responsible for ...
