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
Short-chain fatty acid colon health because it is the primary energy source for colonic cells. Short-chain fatty acid Short-chain fatty acids (SCFAs), also referred to as volatile fatty acids (VFAs), are fatty acids with less than six carbon atoms. Free SCFAs can cross the blood-brain barrier via monocarboxylate transporters. Short-chain fatty acids are produced when dietary fiber is fermented in the colon. Short-chain fatty acids and medium-chain fatty acids are primarily absorbed through the portal vein during lipid digestion, while long-chain fatty acids are packed into chylomicrons and enter lymphatic capillaries, and enter the blood first at the subclavian vein. Short-chain fatty acids
