carbohydrates Flashcards
sugars are a source of stored energy and are called what?
carbohydrates
glucose is a type of simple sugar called a what?
monosaccharide
where is glucose found? what is glucose involved in?
glucose is found in almost every cell and is involved in every chemical reaction that produces energy in living organisms
what is an example of a disaccharide?
table sugar
how is a disaccharide formed?
formed when 2 monosaccharides, glucose and fructose, are covalently bonded
how are disaccharides broken down?
via hydrolytic reactions
what do hydrolytic reactions use water to do?
to break the covalent bonds between monomers
what are polysaccharides?
large polymers built by linking many monosaccharides together
process of forming table sugar
2 monosaccharides are joined by a covalent bond to form a disaccharide
dehydration reactions link monomers, with the release of a water molecule
hydrolytic reactions break monomers apart, with the addition of a water molecule
monosaccharides can bond together to form what?
disaccharides
glucose and fructose are sugar monomers that, when linked by a covalent bond, form what?
the disaccharide sucrose, or table sugar
cellulose and starch are both found in what? what are they made from? how do cellulose and starch differ?
both found in plants and made from glucose, but differ in the way the monosaccharides are linked
what is glycogen? what does glycogen store?
a highly branched polysaccharide that stores energy in animal cells for rapid release when needed
monosaccharides can bond together to form what?
polysaccharides
cellulose, starch, and glycogen are all polymers built from what?
glucose subunits
