Amino acid structure of proteins

Proteini su velike organske molekule neophodne za pravilno funkcioniranje živog organizma. Njihova važnost očituje se u enzimskoj katalizi, prijenosu živčanih impulsa, osiguravanju energije i pravilnog rada imunosnog sustava, a neki od proteina služe za transport malih molekula i iona. U sastavu proteina pronalazimo dvadeset standardnih α-aminokiselina međusobno povezanih peptidnim vezama. Kako svojstva proteina, poput topljivosti, ovise o aminokiselinskom sastavu cilj je ovog završnog rada analizirati aminokiselinski sastav deset polarnih proteina koristeći se informacijama o primarnoj strukturi proteina.Proteins are polymeric organic compounds necessary for proper functioning of living organisms. They have important role in enzyme catalysis, neurotransmission, membrane transport, as well as in immune system. Twenty α-amino acids are building blocks of proteins, where amino acid are linked by peptide bonds. Since solubility of proteins depend on amino acid composition, the aim of these undergraduate thesis was to give information on amino acid composition of ten polar proteins whose primary structure was extracted from literature references
