Review Worksheet for next two problems
|
-----------------------------
|
- The sugar ________ is attached to a steroid and it affects heart rhythm.

- Sugar amines are basic building blocks for ______________ (heparin, etc).
|
- Oubain
- Sugar ester
- Glycosaminoglycans
|
- Glycolipids and glycoproteins are found in what 2 places generally?
- Give an example of each type.
- List the functions of oligosaccharides.
- What is the role of Sialic acid?

Worksheet 7B ------ hemiacetal, hemiketal
|
- Glycoproteins: Secreted by proteins aqueous environment; Glycolipids: Found in cell membrane.
- Glyoproteins: Immunoglobins and Transport Proteins; Glyolipids: Glycophorin
- Protects from degraduation, allows attachment and solubility of proteins, Helps proper folding (steric crowding), Recognition(cell signaling)
- If one of Sialic acids is lost then the protein it was attach to gets degraded by the liver.
- For lysoenzymes to move to lysosomes.
