What are polysaccharides quizlet?
Polysaccharides are polymers of monosaccharaides linked together by dehydration reactions. they are long chains of sugar units that may function as storage molecules or as structural compounds.
What is a monosaccharide quizlet?
Monosaccharide. a simple sugar that is the basic subunit of a carbohydrate.
How are monosaccharides and polysaccharides different quizlet?
Carbohydrates are made up of saccharides, and proteins are made up of amino acids. What are the major differences between mono-, di-, and polysaccharides? Monosaccharides have one monomer, disaccharides have two, and polysaccharides have three or more.
What does polysaccharide mean in biology?
: a carbohydrate that can be decomposed by hydrolysis into two or more molecules of monosaccharides especially : one (such as cellulose, starch, or glycogen) containing many monosaccharide units and marked by complexity.
What are the three main components of polysaccharides quizlet?
Starch, Cellulose and Glycogen are all polysaccharides composed entirely of glucose subunits joined by glycosidic linkages. Glycerol is the molecule that is attached to fatty acids in triacylglycerols.
What is polysaccharide found in?
One example of a polysaccharide found in foods is starch. This is the main carbohydrate source for plant seeds and tubers, or vegetables that grow in the ground. Starch food sources often are referred to as “starchy carbohydrates” and include foods like corn, potatoes and rice.
What are nucleotides quizlet?
Nucleotides. The building blocks of nucleic acids, DNA and RNA, which allow for the expression of genetic traits by specifying the production of proteins. An important class of molecules that are involved in the cell’s use of energy as well as comprising the building blocks of every organism’s genetic material.
What are monosaccharides used for quizlet?
Monosaccharides are used to make larger molecules that are built with repeating units; these are known as polymers, while building blocks are (monosaccharide) monomers. An example of a monosaccharide; molecular formula is C6H12O6.
What do disaccharides and polysaccharides have in common quizlet?
What do disaccharides, such as sucrose, and polysaccharides, such as starch, have in common? -They are lipids made of fatty acids.
What is polysaccharide made of?
Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. Three important polysaccharides, starch, glycogen, and cellulose, are composed of glucose. Starch and glycogen serve as short-term energy stores in plants and animals, respectively. The glucose monomers are linked by α glycosidic bonds.
What is the function of polysaccharide?
Polysaccharides generally perform one of two functions: energy storage or structural support. Starch and glycogen are highly compact polymers that are used for energy storage. Cellulose and chitin are linear polymers that are used for structural support in plants and animals, respectively.
What are the two examples of polysaccharides quizlet?
Terms in this set (4)
- starch. long chains of glucose monomers.
- glycogen. polysaccarides of glucose that animals store.
- cellulose. a polymer of glucose, but its monomers are linked in different orientation.
- chitin. is a structural polysaccharide used by insects and crutsceans to build their exoskeleton.
