convert peptones to polypeptides.
IN THE INTESTINES — Intestinal enzyme peptidase converts peptones,
polypeptides and dipeptides into amino acids.

Fats (Lipids) and their MetabolismFats are one of the “Big Three” componants that all foods have to some
degree. Proteins (amino acids), carbohydrates (sugars) and fats (essential fatty
acids) are the main building blocks, fuels and carriers that your body requires
to keep itself healthy. Fats are vital to your body in numerous ways:
Fats are used as storage units for energy (triglycerides).
Fats provide “padding” or “cushioning” as protection for your internal
organs.
Fats assist with the utilization of fat-soluble vitamins (including A, D and
E).
Fats are used as part of your body’s mechanism to insulate your internal
components and vital organs from environmental conditions (like cold
weather).
Fats guard against internal heat loss.
Fats combine with certain proteins creating diglyceride phospholipids,
which are a part of every cell membrane wall.
Fats serve as anti-inflammatory mediators.As we noted earlier, all components of life, including all foods, are made
up of the four basic elements of oxygen, hydrogen, carbon and nitrogen.
Each component will contain varying amounts of some or all four of these
elements. Water—H 2 0—for example, has two atoms of hydrogen (H 2 )
combined with one atom of oxygen (O). Fats are comprised of mainly carbon
(C), hydrogen (H) and oxygen (O), and are insoluble in water but soluble in
ether and other solvents. Fats are divided up into two basic types, saturated
and unsaturated, and are comprised of fatty acids and glycerol (an alcohol).
Fatty acids are the building blocks of fats, just as amino acids are the
building blocks of proteins. Fatty acids form “chains” through their carbon
bonding. These carbon chains attract hydrogen to them. When each bonding
