,Adipose tissue
• It is the connective tissue in which fat-storing cells or
adipocytes predominate.
• Adipocytes could be found:
• Isolated
• In small groups within loose or dense irregular connective tissue
• In large aggregates in adipose tissue or “fat” in many organs and body regi
• 15%-20% of the body weight in men, somewhat more in women.
, Why do we store fat as triglycerides
• Insoluble in water. Thus, lipids can be
concentrated with no adverse osmotic
effects on cells.
• The caloric density of triglycerides (9.3
kcal/g) is twice that of proteins or
carbohydrates, including glycogen,
making these simple lipids the most
efficient means of storing calories.
Adipocytes specialize in concentrating triglycerides as lipid droplet(s),
other cells normally accumulating relatively little lipid.
