How are glucose sucrose and starch related?
Glucose, sucrose, and starch are all carbohydrates made up of sugar molecules. Glucose is a simple sugar that is a building block for both sucrose (a disaccharide made of glucose and fructose) and starch (a polysaccharide made of multiple glucose units). They are all sources of energy for living organisms.
Why do you suppose the monosaccharide glucose is circulated in the blood of humans rather than a disaccharide such as sucrose which is the transport sugar found in plants?
Glucose is circulated in the blood of humans because it is a monosaccharide that can be rapidly and easily utilized by cells for energy. Its simple structure allows for quick absorption and immediate use, which is essential for maintaining blood sugar levels and providing energy to tissues. In contrast, sucrose, a disaccharide, must be broken down into monosaccharides before it can be utilized by cells, making it less efficient for rapid energy needs in humans. Additionally, glucose plays a critical role in regulating metabolism and hormonal responses in the human body.
What is the bonds of raffinose?
Raffinose is a trisaccharide composed of three sugar units: galactose, glucose, and fructose. The bonds in raffinose include an α-1,6-glycosidic bond connecting galactose to glucose, and an α-1,2-glycosidic bond linking glucose to fructose. This structure makes raffinose a non-reducing sugar, which is not easily digested by humans, often leading to fermentation in the gut and causing gas production.
What polysaccharide cannot be digested by humans?
Cellulose is a polysaccharide that cannot be digested by humans due to the lack of necessary enzyme, cellulase, in our digestive system. It passes through the gastrointestinal tract intact and provides bulk to aid in digestion and promote overall gut health.
What enzyme converts starch to glucose in the mouth of humans?
The enzyme amylase converts starch to glucose in the mouth of humans. Amylase breaks down large starch molecules into smaller glucose molecules that can be absorbed by the body for energy.
Which of the following cannot be digested by humans-sucrose maltose cellulose or fructose?
Cellulose cannot be digested by humans.Cellulosecellulosehumans cannot digest cellulosecelluloseCelluloseCellulose (aka Fiber) can not be digested by humans because, we don't have the bacteria needed to break down cellulose. Sucrose, Maltose, and Fructose are all disaccharides (carbohydrates/sugars) and are all able to be broken down to glucose in the body.

They are all sources of energy for living organisms.
What kind of polysaccharide cannot be digested by human beings?
Humans cannot break down cellulose because it contains beta glucose and the enzymes that humans have cannot break down beta glucose.
Which of these sugars are made by humans glucose fructose mannose starch vitamin c sucrose maltose lactose galactose?
Humans make glucose, fructose, and galactose, as these are monosaccharides that our bodies can produce. The others listed are not made by humans but are consumed through diet or supplementation.

What type of carbohydrate can only be digested by ruminants and not humans by?
cellulose which is present in grass can be digested by ruminants but cannot be digested by humans
What glucose polymers cannot be digested by humans?
cellulose can not be digested by humans..because in human body there is no beta 1-4 glucosidase present.these beta glucosidase cleaves or degrade the glucosidic bond. though termites and cows can digest it and some symbiotic bacteria can digest it.

Can glycogen be digest?
Glycogen can be digested by humans. Chitin and Cellulose, also knows as fiber, can not be digested by humans.
What type of glycosidic bond humans can digest?
Humans can digest α-glycosidic bonds found in starch and sucrose, which are broken down by enzymes like amylase and sucrase.β-glycosidic bonds, found in cellulose and some oligosaccharides, cannot be digested by humans as they lack the necessary enzymes like cellulase.
In humans and other animals where does this glucose come From?
In humans and other animals, glucose primarily comes from the breakdown of carbohydrates in the diet, such as grains, fruits, and vegetables. When these carbohydrates are digested, they are converted into glucose, which is then absorbed into the bloodstream. Additionally, the liver can produce glucose through a process called gluconeogenesis, where it converts non-carbohydrate sources, like amino acids and glycerol, into glucose, especially during fasting or low-carbohydrate intake. This glucose is vital for providing energy to cells throughout the body.
Where is cellulose digested in humans?
Humans can't digest cellulose.
