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.
Carbohydrates have the general molecular formula CH 2 O, and thus were once thought to represent hydrated carbon. However, the arrangement of atoms in carbohydrates has little to do with water molecules. Starch and cellulose are two common carbohydrates.
