Artificial sweeteners give you the sweet taste of sugar without its calories and without raising your blood glucose levels. Depending on the brand used, one packet will usually give the same sweetness as two teaspoons of table sugar. There are two classes of artificial sweeteners: noncaloric (non-nutritive) and caloric (nutritive). Non-caloric sweeteners, such as aspartame, acesulfame-K, sucralose, and saccharin, do not raise blood glucose. Caloric sweeteners, such as sorbitol, mannitol, and xylitol, are sugar alcohols. They have calories and are absorbed into the blood, although more slowly.
Coesite is a very rare mineral that forms in unique ultra high metamorphism usually as a result of meteorite impacts. It was named after American chemist Loring Coes, Jr. (1915-1978), who first synthesized Coesite in 1953 before it was naturally discovered in Barringer Crater in 1960.
A coelom (pronounced seal-um) is a fluid-filled body cavity found in most animals. It is located in the mesoderm, the middle germ layer only found in triploblastic (three-layered) organisms. Simpler animals like cnidarians (jellyfish, coral, etc.) and sponges are diploblastic and monoblastic respectively, lacking a coelom.
