lipofuscins
8 January 2006Lipofuscin is the name given to brown pigment granules composed of lipid-containing residues of lysosomal digestion.
Lipofuscin pigment granules represent undigested material derived from intracellular lipid peroxidation.
Aging
It is considered one of the aging or "wear and tear" pigments. Lipofuscin deposits are found in the liver, kidney, heart muscle, adrenals, nerve cells, and ganglion cells. "Liver spots" commonly associated with aging are superficial dermal lipofuscin deposits. (...) -

mucin-like glycoproteins
7 February 2006Mucin-like glycoproteins, such as heparan sulfate, serve as ligands for the leukocyte adhesion molecule called CD44. These glycoproteins are found in the extracellular matrix and on cell surfaces.
Examples
GlyCAM-1
PSGL-1 (SELPLG)
ESL-1 (GLG1)
CD34
heparan sulfate

cetone bodies
2 June 2004The acetyl-CoA produced by mitochondrial beta-oxidation of fatty acids enters the Kreb’s cycle to produce energy, but that is not the only fate of acetyl-CoA.
In liver mitochondria, some acetyl-CoA is converted to acetoacetate, beta-hydroxybutyrate, and acetone, collectively called ketone bodies.
Ketone bodies are transported to other tissues such as brain, muscle or heart where they are converted back to acetyl-CoA to serve as an energy source.
The brain normally uses only glucose for (...) -
