glucose
is mainly created in
the body from starch digestion and stored by the lover and muscle cells

the only simple sugar that can provide energy for the brain, other nerve cells, and developing red
blood cells.
glucose
the sweetest of simple sugar
fructose
found in honey, most fruits, and some vegetables
fructose
a simple sugar that can be converted into glucose in the body
fructose
not found in foods but produced from lactose (milk sugar) by digestion and is converted into glucose in the body
galactose
a 2 sugar unit
disaccharide
what are the sugars under disaccharide (SLM)
- sucrose
- lactose
- maltose
ordinary table sugar-granulated, powdered or brown
sucrose
processed from cane and beet sugar
sucrose
composed of glucose and fructose.

found in milk and milk products except cheese
lactose
converted into glucose and galactose in
digestion and is less soluble and less sweet than sucrose
lactose
remain in the intestine longer than other sugars and encourages the growth of certain useful bacteria
Lactose
a 2 unit sugar that can not be found free in foods

major food sources include cereal grains,
potatoes and other root vegetables, and legumes
starch
more converted entirely into glucose upon
digestion
starch
more complex than sugars; and requires a longer time to digest, supplying energy over a longer period of time
starch
are not found free in foods and are formed as intermediate products in the
breakdown of starch
dextrin
forms the framework of plants found in unrefined grains, vegetables, and fruits. It is non- digestible by humans
cellulose
no specific enzyme is present and provides
important bulk in the diet which **helps move digestive food ** mass along and stimulates peristalsis
cellulose
main sources are stems and leaves of vegetables,
seed and grain coverings, skins, and hulls
cellulose
_____ are structural parts of plants which are non-digestible because digestive enzymes are unable to break them down
fibers
what are the 2 classification under cellulose

- insoluble
found in fruits and legumes, barleys,
and oats which delay gastrointestinal transit and glucose absorption, and lower blood cholesterol
cellulose soluble
found in wheat bran, corn brans, whole grain bead, cereals, and vegetables which
accelerate gastrointestinal transit, increase fecal weight, slow down starch hydrolysis, and delay
glucose absorption
cellulose insoluble
are non-digestible, colloidal polysaccharides having a gel quality
pectin
sources include mostly fruits and are often used as base for jellies
pectin
are used to treat diarrhea as they absorb toxins and bacteria in the intestine.
pectin
are formed from glucose and stored in liver and muscle tissues

triglycerides
______ & ____ in foods are mostly in the form of triglycerides
Fats, oils
are combination of fats with other components.
compound lipids
they are important part of the cell membrane structure
phospholipids
serve as emulsifiers (allow fat & water to mix by breaking fat globules into small droplets) to
keep fats dispersed in body fluid;
phospholipids
an emulsifier that is most widely distributed and carries fat & cholesterol away from plaque deposits in the arteries.
lecithin
an emulsifier that is needed to form thromboplastin for the blood-clotting process
cephalin
are found in the brain and other nerve tissues as components of
myelin sheath
sphingomyelin
are compounds of fatty acids combined with carbohydrates and
nitrogenous bases
glycolipids
They are lipids combined with proteins. They are insoluble in water and are combined in protein complex for their transport and activity in aqueous medium. They contain cholesterol, neutral fat, and fatty acids.
lipoprotein
also known as bad cholesterol as they carry cholesterol throughout the body.
LDL- low density lipoprotein
it is the “good cholesterol” since they remove cholesterol from the cell and bring it to liver for disposal
HDL - high density lipoprotein
- are simple derivatives from fat digestion
derived lipids
what are the categories of derived lipids
