preventing the digestion and subsequent absorption of protein. For
example, Bowman–Birk trypsin inhibitor is found in soybeans. Lipase
inhibitors interfere with enzymes, such as human pancreatic lipase, that
catalyze the hydrolysis of some lipids, including fats. For example, the
anti-obesity drug orlistat causes a percentage of fat to pass through the
digestive tract undigested.
inhibitors prevent the action of enzymes that break the glycosidic bonds
of starches and other complex carbohydrates, preventing the release of
simple sugars and absorption by the body. Amylase inhibitors, like lipase

magnesium, iron, copper, and zinc. This results in precipitation, making
the minerals unavailable for absorption in the intestines. Phytic acids

broccoli, brussel sprouts, cabbage and cauliflower. Excessive intake of
required nutrients can also result in them having an anti-nutrient action.
Excessive intake of fiber can reduce the transit time through the
intestines to such a degree that other nutrients cannot be absorbed.
Because calcium, iron, zinc and magnesium share the same transporter
within the intestine, excessive consumption of one of these minerals can
lead to saturation of the transport system and reduced absorption of the
other minerals. Some proteins can also be antinutrients, such as the
trypsin inhibitors and lectins found in legumes. These enzyme inhibitors
interfere with digestion. Another particularly widespread form of
antinutrients are the flavonoids, which are a group of polyphenolic
compounds that include tannins. These compounds chelate metals such as
iron and zinc and reduce the absorption of these nutrients, but they also
inhibit digestive enzymes and may also precipitate proteins. Saponins in
plants may serve as anti-feedants.

Sense of Taste
Sweet - Salty - Sour - Bitter
is one of the five traditional
that belongs to
the gustatory system. Taste is the sensation produced when a substance in
the mouth reacts chemically with taste receptor cells located on taste
buds in the oral cavity, mostly on the tongue. Taste, along with smell
(olfaction) and trigeminal nerve stimulation (registering texture, pain,
and temperature), determines flavors of food or other substances. Humans
have taste receptors on taste buds (gustatory calyculi) and other areas
including the upper surface of the tongue and the epiglottis.

(i.e., pleasure) provided by foods or fluids that are agreeable to the
"palate", which often varies relative to the homeostatic satisfaction of
nutritional, water, or energy needs. The palatability of a food or fluid,
unlike its flavor or taste, varies with the state of an individual: it is
lower after consumption and higher when deprived. Palatability of foods,
however, can be learned. It has increasingly been appreciated that this
can create a hedonic hunger that is independent of homeostatic needs.
is a muscular organ in the mouth of most vertebrates that manipulates food
for mastication, and is used in the act of swallowing. It is of importance
in the digestive system and is the primary organ of taste in the gustatory
system. The tongue's upper surface (dorsum) is covered in taste buds
housed in numerous lingual papillae. It is sensitive and kept moist by
saliva, and is richly supplied with nerves and blood vessels. The tongue
also serves as a natural means of cleaning the teeth. A major function of

contain the taste receptor cells, which are also known as
gustatory cells. The taste receptors are located around the small
structures known as papillae found on the upper surface of the tongue,
soft palate, upper esophagus, the cheek and epiglottis. These structures
are involved in detecting the five elements of taste perception: salty,
sour, bitter, sweet and umami; through the combination of these elements
we detect "flavors." A popular myth assigns these different tastes to
different regions of the tongue; in reality these tastes can be detected
by any area of the tongue. Via small openings in the tongue epithelium,
called taste pores, parts of the food dissolved in saliva come into
contact with the taste receptors. These are located on top of the taste
receptor cells that constitute the taste buds. The taste receptor cells
send information detected by clusters of various receptors and ion
channels to the gustatory areas of the brain via the seventh, ninth and
tenth cranial nerves. On average, the human tongue has 2,000–8,000 taste
is a type of receptor which facilitates the sensation of taste. When food
or other substances enter the mouth, molecules interact with saliva and
are bound to taste receptors in the oral cavity and other locations.
Molecules which give a sensation of taste are considered "sapid". Taste
receptors are divided into two families: Type 1, sweet, first
characterized in 2001: TAS1R2 – TAS1R3. Type 2, bitter, first
characterized in 2000: TAS2R1 – TAS2R50, and TAS2R60. Combinations of
these receptors in dimers or other complexes contributes to different
perceptions of taste. Visual, olfactive, “sapictive” (the perception of
tastes), trigeminal (hot, cool), mechanical, all contribute to the
perception of taste. Of these, transient receptor potential cation channel
subfamily V member 1 (TRPV1) vanilloid receptors are responsible for the
perception of heat from some molecules such as capsaicin, and a CMR1
receptor is responsible for the perception of cold from molecules such as
menthol, eucalyptol, and icilin.

Scents - Smells
The Power of Smell
"The human nose can distinguish at least 1 trillion different odours?"
is the sense of smell. This sense is mediated by specialized
of the nasal cavity of vertebrates, which can be considered analogous to
sensory cells of the antennae of invertebrates. In humans, olfaction
occurs when odorant molecules bind to specific sites on the olfactory
receptors. These receptors are used to detect the presence of smell. They
come together at the glomerulus, a structure which transmits signals to
the olfactory bulb (a brain structure directly above the nasal cavity and
below the frontal lobe).
is the part of the sensory
used for smelling (olfaction). Most mammals and reptiles have a
main olfactory system and an accessory olfactory system. The main
olfactory system detects airborne substances, while the accessory system
senses fluid-phase stimuli. The senses of smell and taste (gustatory
system) are often referred to together as the chemosensory system, because
they both give the brain information about the chemical composition of
objects through a process called transduction.
Smelling is a chemical sense
that is stimulated by substances such as
irritant solutions or vapours capable of exciting receptors in mucous
membranes of the nose, mouth, eyes, and respiratory tract. Your ability to
smell comes from specialized sensory cells, called olfactory sensory
neurons, which are found in a small patch of tissue high inside the nose.
These cells connect directly to the brain. Each olfactory neuron has one
odor receptor. Once the neurons detect the molecules, they send messages
to your brain, which identifies the smell. There are more smells in the
environment than there are receptors, and any given molecule may stimulate
a combination of receptors, creating a unique representation in the brain.
These representations are registered by the brain as a particular smell.
Smells reach the olfactory sensory neurons through two pathways. The first
pathway is through your nostrils. The second pathway is through a channel
that connects the roof of the throat to the nose. Chewing food releases
aromas that access the olfactory
the second channel. If the channel is blocked, such as when your nose is
stuffed up by a cold or flu, odors can’t reach the sensory cells that are
stimulated by smells. As a result, you lose much of your ability to enjoy
a food’s flavor. In this way, your senses of smell and taste work closely
together. Without the olfactory sensory neurons
familiar flavors such as chocolate or oranges would be hard to
distinguish. Without smell, foods tend to taste bland and have little or
no flavor. Some people who go to the doctor because they think they’ve
lost their sense of taste are surprised to learn that they’ve lost their
sense of smell instead. Your sense of smell is also influenced by
something called the common chemical sense. This sense involves thousands
of nerve endings, especially on the moist surfaces of the eyes, nose,
mouth, and throat. These nerve endings help you sense irritating
substances—such as the tear-inducing power of an onion—or the refreshing
coolness of menthol.

responsible for a compound's different detection threshold is not well
understood. As such, odor thresholds cannot be accurately predicted.
Rather, they must be measured through extensive tests using human subjects
in laboratory settings. Optical isomers can have different detection

is the inability to perceive odor or a lack of functioning olfaction—the
loss of the sense of smell. Anosmia may be temporary, but some anosmia
(including traumatic anosmia) can be permanent. Anosmia is due to a number
of factors, including an inflammation of the nasal mucosa, blockage of
nasal passages or a destruction of one temporal lobe. Inflammation is due
to chronic mucosa changes in the paranasal sinus lining and the middle and
is the temporary, normal inability to distinguish a
particular odor after a prolonged exposure to that airborne compound. For
example, when entering a restaurant initially the odor of food is often
perceived as being very strong, but after time the awareness of the odor
normally fades to the point where the smell is not perceptible or is much
weaker. After leaving the area of high odor, the sensitivity is restored
with time. This is one of the reasons why we can't tell how bad we smell
because we adapt to smells very quickly.
is an olfactory dysfunction that is characterized by the inability of the
brain to properly identify an odor's "natural" smell. What happens
instead, is that the natural odor is transcribed into what is most often
described as an unpleasant aroma, typically a "'burned,' 'rotting,'
'fecal,' or 'chemical' smell." There are instances, however, of pleasant
odors. This is more specifically called euosmia (Gk.).
