In fact, this butt-sniffing action is just one of many examples of chemical communication in the animal kingdom .. Of course, a dog's sense of smell is famously acute--10,000 to 100,000 times more acute than our own, according to the video.he answer to that question is a bit more complicated than you might imagine. According to a new video from the American Chemical Society (above), it's all about one canine literally sniffing out important information about the other--its gender, emotional state, diet, and more.
Valine. L-valine is a branched-chain amino acid (BCAA) . Other branched chain amino acids are isoleucine and leucine. Valine is an aliphatic amino acid that is closely related to leucine and isoleucine both in structure and function. Valine differs from threonine by replacement of the hydroxyl group with a methyl substituent.
The name carbohydrate reveals the chemical make up of this nutrient class. Indeed, carbo means carbon, while hydrate means water, a combination of hydrogen and oxygen molecules. All carbohydrates, including sugar, therefore contain the same three elements: carbon, hydrogen and oxygen. Different arrangements of these elements form single units to make different types of carbohydrates. Glucose, for instance, is a single-unit carb with six carbon atoms, 12 hydrogen atoms and six oxygen atoms.
