starch molecules
Glucose Glucose units come together to form large cellulose and starch molecules.
glucose glucose units come together to form large cellulose and starch molecules.
The subunits that polymerize to form starches are glucose molecules. Glucose molecules link together through glycosidic bonds to form starch polymers. Starch is composed of two types of polymers: amylose, which is a linear chain of glucose molecules, and amylopectin, which is a branched chain of glucose molecules.
a polymer
The backbone of carbon in a carbohydrate comes from simple sugar molecules like glucose. These sugar molecules link together in chains to form the structure of a carbohydrate.
Fifteen molecules of glucose can be used to form polysaccharides, specifically starch or glycogen, through a process called polymerization. In this process, the individual glucose molecules undergo dehydration synthesis, where water is removed to link them together. The resulting macromolecule will consist of a long chain of glucose units, serving as an energy storage form in plants (starch) or animals (glycogen).
The most common monomer for polysaccharides is glucose. Glucose molecules link together to form long chains in polysaccharides like starch, cellulose, and glycogen.
maltose The boding of two glucose units forms maltose. The glycosidic link joins the number carbon of one glucose to the number 4 carbon of the second glucose. Joining the glucose monomers in a differnet way would result ina differnet disaccharide.
Glucose in animals is stored as glycogen. Glycogen is a polymer of glucose subunits attached with alpha (1-4) glycosidic linkages to link the individual glucose molecules, and alpha (1-6) linkages to create branch points for larger branched molecules. It is very similar to plant's energy reserve macromolecule - starch.
Sucrose is a disaccharide composed of an alpha-glucose and an alpha-fructose. It has an alpha 1-2 glycosidic linkage between the two molecules.
Glycogen is made through a process called glycogenesis, which involves converting excess glucose molecules into glycogen for storage in the liver and muscles. This process is facilitated by enzymes such as glycogen synthase, which link glucose molecules together to form glycogen chains. Glycogen can be broken down back into glucose through a process called glycogenolysis when the body needs energy.
Carbohydrates are made up of molecules called monosaccharides, which are simple sugars such as glucose, fructose, and galactose. Monosaccharides can link together to form larger carbohydrates like disaccharides (e.g. sucrose, lactose) and polysaccharides (e.g. starch, glycogen, cellulose).
