There are two class of protein based on their structure namely fibrous and globular. Globular proteins form a globe like spherical structure in contrary to rod like fibrous proteins (collagen). They are soluble in water and the structure is rendered by its three dimensional arrangement of amino acids in solution. Most of the enzymes, soluble hormones and factors fall into this class of proteins.
Receptor proteins, recognition proteins, transport proteins, and enzymatic proteins.
Foods contain proteins, carbohydrates and lipids which are three different types of macromolecules. However, there are far more than three types of macromolecules, some of which are also found in food.

Embedded in the semi-permeable cell membrane are many different types of carrier proteins or channel proteins. These globular proteins allow the transport of specific substances from the outside of the cell into the cell or vice versa.Specific means each protein can only transport one type of substance across. For example, Protein A can transport Substance X but not Substance Y. Substance Y has to be transported by Protein B which cannot transport Substance X. The specific nature of these globular proteins mean it is easier for these molecules to be transported.

There are two main types of proteins namely; simple proteins and conjugated proteins. Simple proteins only contain amino acids while conjugated proteins contain organic and inorganic groupings in addition to amino acids.

There are three types of proteins that are found in the plasma of blood. They are albumin, globulins, and fibrinogens.

They have different structure types. Hemoglobin is a globular protein, where it has a globular shape from the folding of amino acids by the hydrophobic effect. alpha-Keratin (the protein in hair), on the other hand, has a helical structure, with a repeating pattern of amino acids. Hemoglobin does not have a continuous repeating pattern of amino acids.
Foods can be grouped in various ways according to their nutritional content, source, or type. For example the three main types of foods are proteins, carbohydrates, and fats. Then there are the micronutrients like vitamins and minerals. Some of the best sources of vitamins and minerals are found in fruits and vegetables.
