Secreted
glycoproteins
(not to scale)
Monosaccharides
Found in the cytosol and in organelles
Use for energy production and in biosynthesis
Simple polysaccharides
Glycogen and starch polymers of glucose
Glycogen in granules in cytoplasm in muscle and liver cells
Glycosoaminoglycans
GAGs
Linear,
unbranched
polysaccharide with
dissacharide
repeat of a hexose and
hexosamine
monsacharide
Highly charge with carboxyl and sulfate groups
Properties (high viscosity, low compressibility) useful for joints
Glycolipids
Found in cell membrane
Involved in signaling across the membrane
Recognition sites for ligands
Secreted proteoglycans
GAGS covalently attached to protein core
components of the extracellular matrix
Involved in cell signaling and cell binding
