5 Questions
What are the major roles of fat at the cellular level?
Fat plays important roles at the cellular level as it is an essential part of cell membranes. Complex glycolipids, phospholipids, and cholesterol are major components of biological membranes. Some fatty acids are related to the response to inflammation and control gene expression in the cell.
Explain the importance of fat in the human diet and body?
Fat is essential in the diet as it provides energy, cushions organs, insulates for temperature regulation, and facilitates absorption of fat-soluble vitamins in the small intestine. It is also a major storage form of metabolic energy in animals and an essential part of cell membranes.
What is the significance of cholesterol in the body?
Cholesterol is a precursor of the steroid hormones and bile salts. It is also a major component of biological membranes and plays a role in the synthesis of important signaling molecules such as prostaglandins, thromboxanes, and leukotrienes.
How does the human body utilize the fat depot during times of starvation?
The fat depot can be used for energy during times of starvation. Triacylglycerols, the major storage form of metabolic energy in animals, are mobilized to provide energy when food intake is limited.
What are the functions of arachidonate, a C20 unsaturated fatty acid?
Arachidonate is the precursor of the prostaglandins, thromboxanes, and leukotrienes, which are potent inflammatory mediators and play important roles in immune responses and other physiological processes.
