Chapter 5, Problem 11PIAT
Summary Introduction
To review:
The type of glycosidic bond linking monosaccharides α-glucose and β-fructose in disaccharide, sucrose.
Introduction:
Sucrose is a disaccharide made up of monosaccharides α-d-glucose and β-d-fructose. The two monosaccharides of the sucrose are joined by an ether bond called the glycosidic bond. The bond is formed by the condensation reaction in which a molecule of water is released.

- If both cellulose and starch are just polymers of glucose, why can we only get glucose from starch, while cellulose cannot be digested by our bodies? What is missing for cellulose?arrow_forwardA polysaccharide is a polymer of (choose the best answer) sugars, and they could be made of 3-carbon, -5-carbon, or 6-carbon rings or chains O nucleic acids, and because of that, they contain the directions for making proteins fatty acids, and as such are critical for the formation of cell membranes none of the answers are correct amino acids, and as such, their function depends on their 3D shapearrow_forwardHow important are lipids in our body?

What are two possible interpretations of this result? (Hint: Think about the possibility that, before digestion, milk contains either a disaccharide or a monosaccharide.)arrow_forward
- Why is it important to include cellulose in a healthy diet even though we do not digest it?arrow_forwardAll cells in your body contain glycoproteins (proteins with short oligosaccharide chains attached, Chapter 18) as part of the cell membrane. The carbohydrate part of a glycoprotein extends out of the membrane into the intercellular fluid and is the signaling part of the molecule. Red blood cells have specific glycoproteins that we use to specify the different blood types. Which sugars and sugar derivatives are found in all blood types?
