A gluten allergyânot to be confused with gluten sensitivity or celiac diseaseâis caused by gliadin, a glycoprotein that, along with glutenin (another protein), helps to form the gluten protein. Gluten is found in wheat and other related grains such as barley, oats, and rye.Gliadin is also one of the major allergens associated with wheat allergies and a trigger for celiac disease, a serious autoimmune disorder of the small intestine.Unlike a gluten allergy, in which small amounts of gluten may be tolerated, a patient with celiac disease cannot tolerate any gluten at all.liadin is also one of the major allergens associated with wheat allergies and a trigger for celiac disease, a serious autoimmune disorder of the small intestine.

The first vertebrates to come onto land were fish-like animals that developed lungs and could thus stay on land for extended periods.These evolved into terrestrial amphibians â¦ (although many amphibians require water in which to lay eggs, and some are aquatic).he common name for aquatic vertebrates are fish. The group of vertebrates that are terrestrial (land-dwelling) are called tetrapods. The first tetrapods evolved in the late Devonian.
THE DEVONIAN PERIOD (about 410 to 360 million years ago) THE FIRST LAND ANIMALS EVOLVE. The ancestry of all land animals, including the dinosaurs, can be traced back over 400 million years to the Devonian Period. During this period some animals moved to land from the water. The reason for this is that the land had food resources that had not been exploited.
