Detailed explanation-1: -The diversity of proteins is caused due to the varying sequence resulting from alternating proportions of amino acids. An indefinite variety of protein sequences are formed due to highly fluctuating combinations of amino acids.
Detailed explanation-2: -Proteins come in a wide variety of shapes, and they are generally between 50 and 2000 amino acids long. Large proteins generally consist of several distinct protein domains-structural units that fold more or less independently of each other, as we discuss below.
Detailed explanation-3: -The chief characteristic that allows proteins’ diverse functions is their ability to bind specifically and tightly with other molecules. We cannot make all the amino acids we need to synthesize our own proteins, so we must obtain some of them from proteins in the foods we consume.
Detailed explanation-4: -Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective; they may serve in transport, storage, or membranes; or they may be toxins or enzymes.
