Study Notes
Sources of Fat in Adipocytes
- Fat stored in adipocytes primarily comes from dietary intake, de novo lipogenesis (conversion of carbohydrates to fat), and re-esterification (re-formation of triglycerides from free fatty acids and glycerol).
Factors Influencing Fat Deposition and Utilization
- The rate of fat deposition and breakdown within adipose tissue is influenced by hormonal signals (insulin, glucagon), energy balance (caloric intake vs. expenditure), and enzyme activity (lipoprotein lipase, hormone-sensitive lipase).
Distribution of White Adipose Tissue
- White adipose tissue is primarily distributed in subcutaneous areas (under the skin), around internal organs (visceral fat), and within bone marrow.
Functions of Adipose Tissue
- Main functions include energy storage, insulation to maintain body temperature, cushioning for organs, and endocrine roles by secreting hormones like leptin and adiponectin, which regulate metabolism and appetite.
Blood Supply in Adipose Tissue
- Adipose tissue generally has a rich blood supply, which is essential for delivering nutrients, hormones, and oxygen, as well as facilitating the removal of metabolic waste.
