Mono
GLUCOSE
Body’s main source of energy
most common ms found in nature
plants created at photosynthesis
Glucose
Most concentrated whole food source of glucose
Honey
Fruit sugar
Fructose
is the sweetest naturally occurring cho and is 1.2 - 1.8 times sweeter than sucrose (table sugar)
Their metabolism does not require insulin and has a low impact on blood glucose levels.
Ms
Fructose
Found by itself in the diet.
lactose
MS
Galactose
Molecules formed by two monosaccharides joined
by a glycosidic bond
Disaccharides
Glucose + galactose = DS
Lactose
Milk sugar
only found naturally in the milk of mammals
Lactose
Glucose + Glucose
Maltose
A product of the hydrolysis of starch
Maltose
Glucose + fructose
Sucrose
Table sugar
Sucrose
It can be in plants, fruits and veggies
And also in candy, cereals, soda, etc
Sucrose
Molecules formed by large amounts of MS connected by glycosidic bonds
Polysaccharides
Mainly: Amylose and amylopectin
Large number of glucose molecules
Starch
is manufactured in the leaves of plants from excess glucose produced during photosynthesis and serves the plant as a reserve food supply
Starch
Stored in chloroplasts
Starch
Most of the nutritional value of food comes from
Starch
This stored form of glucose is made up of many connected glucose molecules.
It is found in greatest abundance in liver and muscle cells
Glycogen
Many connected glucose
Glycogen
