Of the three groups of biopolymers, protein have the most diverse function. Most of its molecular weights are much larger. Their shaps cover a range from the globular protein to the helical coils of a α–keratin. But all proteins have common features. Proteins are polyamides and their monomeric units are about 20 different α-amino acids
The nucleic acids, deoxyribonucleic (DNA) and ribonucleic (RNA) , are, respectively , the molecules that preserve hereditary information and that transcribe and translate it in a way that allows the synthesis of all the varied proteins of the cell 25.2 NUCLEOTIDES AND NUCLEOSIDES
