'A' is a protein. Proteins are essential for growth and repair of body tissues. There are 20 different types of amino acids which can be combined to form different stuctures. Each structure determines the function of the protein. Proteins act as enzymes, messengers, are involved in structural support, body movement and helps build defence against germs. Pepsin and lactase are enzymes whereas haemoglobin is a messenger protein. Folic acid on the other hand, is a pro-vitamin.
