Bone exclusively with red marrow or hematopoietic marrow, but as the child ages the hematopoietic fraction decreases in quantity and the fatty/ yellow fraction called marrow adipose tissue (MAT) increases in quantity. In adults, red marrow is mostly found in the bone marrow of the femur, the ribs, the vertebrae and pelvic bones. Bone is a metabolically active tissue composed of several types of cells. These cells include osteoblasts, which are involved in the creation and mineralization of bone tissue, osteocytes, and osteoclasts, which are involved in the reabsorption of bone tissue. Osteoblasts and osteocytes are derived from osteoprogenitor cells, but
Furan fatty acids specifically trap hydroxyl radicals. It is therefore believed that this is in different biological systems their main function. They also inhibit the singlet oxygen-induced hemolysis of red blood cells (red blood cell disintegration). Plants and algae produce furan fatty acids during the biosynthesis from polyunsaturated fatty acids (PUFA). These are seemingly used in these organisms as protection against free radicals generated by sunlight. Occasionally it is speculated that the health-promoting properties originally attributed to omega-3 fatty acids may not be based on themself, but on the furan fatty acids also present in the fish.
