Describe lipid digestion



In the mouth and stomach: Little fat digestion takes places
In the Small Intestine: Digestive enzymes accomplish most fat digestion (in small intestine). There, bile emulsifies fat, making it available for enzyme action. The enzymes cleave triglycerides into three fatty acids, glycerol, and monoglycerides.
The Intestinal Lining: The parts are absorbed by the intestinal villi. Glycerol and short-chain fatty acids enter directly into the bloodstream.
The cells of the intestinal lining convert large lipid fragments, such as monoglycerides and long-chain fatty-acids, back into triglycerides and combine them with protein, forming chylomicrons (a type of lipoprotein) that travel in the lymph vessels to the bloodstream.
In the large intestine: A small amount of cholesterol trapped in fiber exits with the feces.

Why do firms need to invest in net working capital? Answer: - Short-term financial planning is concerned with the management of the firm's short-term, or current, assets and liabilities.

The most important current liabilities are bank loans and trade payables. - The difference between current assets and current liabilities is called NET WORKING CAPITAL (NWC).
