2 In the discussion of digestion of carbohydrates; nouns ending in the suffix -ose usually
indicate a sugar, such as lactose. Nouns ending in the suffix -ase indicates the enzyme that
will break down the sugar, such as lactase. Enzymes usually begin with the substrate
(substance) they are breaking down. For example: maltose, a disaccharide, is broken down
by the enzyme maltase (by the process of hydrolysis), resulting in a two glucose molecules,
a monosaccharide.
3 Swallowing, known scientifically as deglutition, is the reflex in the human body that makes
something pass from the mouth, to the pharynx, into the esophagus, with the shutting of
the epiglottis. If this fails and the object goes through the trachea, then choking or
pulmonary aspiration can occur. For a more detailed representation of swallowing, see

5 Denaturation is the major change in protein or nucleic acid structure by application of
some external stress for example, treatment of proteins with strong acids or bases, high
concentrations of inorganic salts or organic solvents (e.g., alcohol or chloroform), heat,
which results in improper functioning of cell activity. Denatured proteins can exhibit a
wide range of characteristics, from loss of solubility to communal aggregation. Proteins are
very long strands of amino acids linked together in specific sequences.
6 An emulsion is a mixture of two immiscible (unblendable) substances. One substance (the
dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions
include butter and margarine, milk and cream, espresso, mayonnaise, the photo-sensitive
side of photographic film, and cutting fluid for metal working. In butter and margarine, a
continuous liquid phase surrounds droplets of water (a water-in-oil emulsion). In milk and
cream, oil is dispersed within a continuous water phase (an oil-in-water emulsion).
Emulsification is the process by which emulsions are prepared. See

33 Glycemic index (also glycaemic index, GI) is a ranking system for carbohydrates based
on their effect on blood glucose levels. It compares available carbohydrates gram for gram
in individual foods, providing a numerical, evidence-based index of postprandial (postmeal)
glycemia. The concept was invented by Dr. David J. Jenkins and colleagues in 1981
at the University of Toronto. Carbohydrates that break down rapidly during digestion
have the highest glycemic indices. Carbohydrates that break down slowly, releasing
glucose gradually into the blood stream, have a low glycemic index. A lower glycemic
index suggests slower rates of digestion and absorption of the sugars and starches in the
foods and may also indicate greater extraction from the liver and periphery of the products
of carbohydrate digestion. A lower glycemic response is often thought to equate to a lower
insulin demand, better long-term blood glucose control and a reduction in blood lipids.
