1 contribute to the mechanical structure of animals, including humans, e.g. keratin in hair and fingernails, and fibrous proteins such as collagen in tendons. 2  enable animals to move, e.g. myosin in muscle.  facilitate transport of smaller molecules around animals' bodies, e.g. haemoglobin.
Membrane Protein Types and Structures. The structure of membrane proteins often determines their function. This, in turn, is the way we classify the type of membrane protein. In general, integral proteins are embedded within the hydrophobic layer of the membranes. Peripheral proteins are not embedded within the hydrophobic region of the membrane. Instead, they are associated with the hydrophilic heads or with an integral membrane protein.
