fats are phospholipids, phosphatids, and lipoproteins. Phospholipids is a fat that
contains a phosphate group and is found in cell membranes. Phosphatides are
compounds consisting of fats, phosphates, and choline. While lipoproteins are
compounds that are composed top fats and proteins. The derived fats are
compounds resulting from the fat hydrolysis process. For example, fatty acids,
steroids, glycerol, and cholesterol.
Based on the degree of saturation, fatty acids as one of the derived fats can
be divided into two types, including fatty acids saturated and unsaturated fatty
acids. Saturated fatty acids are fatty acids that can be synthesized in the body, so
they are non-essential it is usually found in animal fats with a solid form.
Examples are stearic acid, palmitic acid, and butter. Meanwhile, unsaturated fatty
acids are fatty acids that are not can be synthesized in the body, so its properties
are essential. Fatty acids unsaturated is abundant in vegetable fats and generally
takes the form of liquid. For example, oleic acid, ilnoleic acid, arachhidonic acid,
oil corn, and soybean oil.

Figure 4. Classification of fats

Food sources containing fats

include animal fats and vegetable fats.

Vegetable fats are fats derived from

herbs such as palm oil, coconut oil, and

peanut. While animal fats are fats

derived from animals, for example, fat

on meat, butter, milk, and egg yolk.

Every 1 gram of fat can produce energy
of 9.3 calories.
