Question
Which best describes bond #1?
[1,6]
[2,4]
[1,6]
None of these choices is a proper description.
[2,4]
2. Choose all of the statments which correctly describe glycoproteins.
Glycoproteins:
are synthesized only in labs, not by cells.
contain one or more monosaccharides.
are used to store energy in cells.
are used for cell-cell recognition at the cell membrane.
contain amino acids.
contain only beta-linked carbohydrates.
3.
The cyclic form of sugars
has one more chiral center (the anomeric carbon) than the open-chain form.
loses a chiral center compared to the open-chain form.
is not usually found in nature.
has one more carbon atom than the open-chain form.
has one less carbon atom than the open-chain form.
4.
Glycosaminoglycans play a major role in:
storing energy for animal cells
storing energy for plant cells
catalyzing chemical reactions at the cell membrane.
connective tissues at joints.
forming a helical structure to support the cell membrane.
