Carbohydrates Flashcards
compounds composed of
carbon, oxygen, and hydrogen arranged as
monosaccharides.
Originally called saccharides (a Greek word,
meaning sugars)
Carbohydrates
1 sugar unit
monosaccharides
2 sugar units
disaccharides
3 to 10 sugar units
Oligosaccharides
More than 10 sugar units
Polysaccharide
sugar, starches, dextrin and glycogen
Digestible
galactogens, mannosans,
inulin and pentosan
Partially digestible
cellulose and hemicellulose only
digestible carbohydrates supply energy upon
complete hydrolysis (1 gram yields 4 kcal)
Indigestable
Are simple sugar units that compromise the
general formula in a single ring. In this case,
they form the structure. It is divided by their
arrangements of atoms that may counter the
level of sweetness: glucose, fructose, and
galactose.
Monosaccharides
also known as dextrose or grape sugar or
physiologic sugar or blood sugar
most important sugar in human metabolism
Glucose
Also known as Fruit Sugar
Sweetest of all sugars
Fructose
Also known as milk sugar
hydrolyzed from lactose or milk sugar
Galactose
Five-carbon chains of monosaccharides found
in nucleic acids of meat and seafood’s in bound
form
* In the body, they are important components
of nucleic acids and some co-enzymes
Pentose
pairs of monosaccharides
linked together. Types of disaccharides are the
following: maltose, sucrose, and lactose.
Disaccharide
Also called malt sugartwo glucose units that are produced from
starch digestion
found mostly in grains such as barley
Maltose
