Earth is approximately spherical in shape like all planets and stars. Earth is composed mostly of rock. Three-fourths of its surface is covered by a relatively thin layer of water (some of it frozen), and the entire planet is surrounded by a relatively thin blanket of air.
The digestive enzyme that hydrolyzes lipids, acts as catalyst for the hydrolysis of lipid, aids emulsification of fat, and keeps tiny fat droplets suspended in the aqueous content of the gut is LIPASE. This enzyme is a subclass of esterases that breakdown fats to fatty acids and glycerol and other alcohols.
