MALDI-MS argininyl bufadienolide esters fingerprint from parotoid gland secretions of Rhinella arenarum: Age, gender, and seasonal variation
In many amphibians, the granular glands can be grouped in special regions forming macroglands. This is the case of toads, characterized by the presence of a pair of parotoid macroglands, strategically located to give protection by poison release in case of attacks. The product secreted consists of a...
