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.
The next broad category of proteins we will consider are the carrier molecules or transport proteins. These transport proteins are often globular proteins. They are generally tightly packed with polar side groups on the outside to enhance their solubility in water. They typically have nonpolar side groups folded to the inside to keep water from getting in and unfolding them. Serum albumin is one example.
