Macronutrients

Carbohydrates

r

Very important source of quick energy.Most abundant biomolecules on Earth.Serve as important structural components.

Monosaccharides

r

Simple sugars.They are the smallest unit that make up carbohydrates. They are the building blocks.

ex: Glucose

ex: Fructose

ex: Galactose

Disaccharaides

r

Made up of 2 monosaccharides

ex: Maltose

r

2 glucose molecules stuck together.

Oligosaccharides

r

Short chain of monosaccharidesLess than 20 monosaccharides linked together.A disaccharide can be referred to as an oligosaccharide.

ex: Maltotriose

r

Contains 3 glucose molecules.

Polysaccharides

r

More than 20 monosaccharides with 20 bonds, it becomes a Polysaccharide.Most carbohydrates in nature are found as polysaccharides.Known as Glycans

Homopolysaccharides

r

Contains only a single type of monosaccharide. ex: only glucose molecules linked together.Can be unbranched or branched.

ex: Starch

r

Storage for monosaccharides in plants. It is the main carbohydrate in the human diet.Only made up of glucose.Unbranched = AmyloseBranched = Amylopectin

ex: Glycogen

r

Unbranched = AmyloseBranched = AmylopectinBranch points occur more frequently in Glycogen

ex: Cellulose

r

Structural components in plants. They make up the cell wall.

ex: Dextron

r

Structural components in bacteria and yeast.

Heteropolysaccharides

r

Contains 2 or more types of different monosaccharides. ex: a long chain of fructose and glucose molecules.can be unbranched or branched.
