Oleinska kislina

titracijske krivulje in tvorba dvoplasti

Lena Trnovec (Author), Ksenija Kogej (Mentor)

Abstract

Oleinska kislina s formulo C18H34O2H sodi med omega-9 maščobne kisline. Med naravnimi maščobnimi kislinami je najbolj razširjena. Sodeluje pri proizvodnji celične energije in drugih metabolnih funkcijah, zato je bistvena za človeško telo. Zelo pomembna je v prehrani, saj jo povezujejo z zmanjševanjem možnosti za krvno-žilne bolezni in poročajo celo, da preprečuje raka. Oleinska kislina lahko v določenih pogojih tvori lipidne vezikle, pri tem pa je ključno razmerje med njeno ionizirano in neionizirano obliko. V tem diplomskem delu bom pregledala obstoječo literaturo na te (in druge) teme. V laboratoriju pa bom določila titracijsko krivuljo za oleinsko kislino in pogledala, kakšen je njen vpliv na stabilnost lipidnih veziklov.

Secondary title:	Oleic acid: titration curves and bilayer formation
Secondary abstract:	Oleic acid is an omega-9 fatty acid with the formula C18H34O2H. It is the most common of the natural fatty acids. It is involved in the production of cellular energy and other metabolic functions and is therefore essential for the human body. It is very important in the diet because it reduces the risk of cardiovascular disease, and it was even reported to prevent cancer. Under certain conditions, oleic acid can form lipid vesicles, where the ratio between its ionized and non-ionized forms is the key factor. In this thesis, I will review the existing literature on these (and others) topics. In the laboratory, I will determine the titration curve for oleic acid and investigate its effects on the stability of lipid vesicles.
