Question
"hello!
sir!
is there any salvary amylase in the saliva(i.e mouth) of herbivore
our teacher has said that there is no amylase in the saliva of herbivore and if it is present that is in stomach of little quantity."pleeeeeeeeees solve
Thanks for using AllExperts. So far as I am aware, the saliva of herbivores does indeed contain salivary amylase; it is essential for herbivores, whose diet consists entirely of plants (and thus is heavily composed of carbohydrates). Salivary amylase (a type of alpha amylase) begins the digestion of carbohydrates by cleaving large-chain polysacchardies. The digestion is completed in the small intestine, where pancreatic amylase digests the remaining small polysaccharides and disaccharides into monosaccharides that can then be absorbed. Perhaps your teacher made a simple mistake: salivary amylase is absent from strict carnivores, which makes sense--they have no use for it. Herbivores do have salivary amylase, which is what you would intitutively expect.

I will answer all biology-related questions through the undergraduate level. I will explain unclear concepts and suggest approaches to solving problems, but would prefer not to completely solve homework problems for you. If you are completely stumped on homework, tell me what you already know and I will help you as much as possible. Please do not ask me for ideas on school research projects; part of research is determining a suitable area of investigation, and that's not a task that should be completed by someone else. Please don't simply send me your homework for solutions. If you are having difficulty after you have started an analysis, I will be happy to direct your thinking; in particular, I would prefer to not simply solve pedigrees for students, but I will be happy to assist in solving pedigrees that you have already started. If you don't understand how to analyze a pedigree, I'd highly recommend watching this video, in which a biology professor explains the basic concepts of pedigree analysis: http://www.youtube.com/watch?v=HbIHjsn5cHo
