Detailed explanation-1: -Bile aids in the digestion of lipids, primarily triglycerides, through emulsification. Emulsification is a process in which large lipid globules are broken down into several small lipid globules.
Detailed explanation-2: -Emulsification: In the small intestine lipids are emulsified by bile salts. Bile salts (bile salts = conjugation of bile acids with taurine or glycine) are polar and water soluble and function as detergents whereby they emulsifies larger fats into smaller droplets.
Detailed explanation-3: -In the small intestines bile emulsifies fats while enzymes digest them. The intestinal cells absorb the fats. Long-chain fatty acids form a large lipoprotein structure called a chylomicron that transports fats through the lymph system.
Detailed explanation-4: -Bile enters the duodenum emulsifying fats into smaller globules, which can then be broken down further by lipase enzymes. Metabolic wastes and drug products may form part of the bile which can then be excreted from the body through the digestive tract in the faeces.
