Grapefruit IntegroPectin is a new and innovative type of citrus pectin obtained from grapefruit peels, a by-product of the agri-food industry, through hydrodynamic cavitation. It is characterized by a high content of bioactive compounds, such as terpenes and flavonoids, known for their antioxidant and anti-inflammatory effects, as this pectin also preserves the structure of the RG-I domain. This suggests that this biopolymer may exert a variety of positive effects on different biological targets; therefore, the aim of this study is to evaluate the bioactive properties and structural characteristics of IntegroPectin through complementary experimental and computational approaches. Its ability to modulate specific signaling pathways, along with its antioxidant, anti-inflammatory, and antiproliferative properties, makes IntegroPectin a promising bioactive molecule for further investigation aimed at developing new therapeutic and nutraceutical strategies. This thesis fully aligns with the goals of sustainable development, exploring the valorization of agricultural by-products in various applications.
Grapefruit IntegroPectin è una nuova e innovativa tipologia di pectina di agrumi ottenuta dalle scorze di pompelmo, sottoprodotti dell’industria agroalimentare, tramite cavitazione idrodinamica. È caratterizzata da un elevato contenuto di composti bioattivi, come terpeni e flavonoidi, noti per i loro effetti antiossidanti e antinfiammatori, poiché questa pectina preserva anche la struttura del dominio RG-I. Ciò suggerisce che questo biopolimero possa esercitare una molteplicità di effetti positivi su diversi target biologici; pertanto, lo scopo di questo studio è valutare le proprietà bioattive e le caratteristiche strutturali dell’IntegroPectin attraverso approcci sperimentali e computazionali complementari. La sua capacità di modulare specifici pathway di segnalazione, insieme alle proprietà antiossidanti, antinfiammatorie e antiproliferative, rende l’IntegroPectin una promettente molecola bioattiva per ulteriori indagini finalizzate allo sviluppo di nuove strategie terapeutiche e nutraceutiche. Questa tesi si colloca pienamente negli obiettivi dello sviluppo sostenibile, esplorando la valorizzazione dei sottoprodotti agricoli in diverse applicazioni.

Abstract
Grapefruit IntegroPectin is a new and innovative type of citrus pectin obtained from grapefruit peels, a by-product of the agri-food industry, through hydrodynamic cavitation. It is characterized by a high content of bioactive compounds, such as terpenes and flavonoids, known for their antioxidant and anti-inflammatory effects, as this pectin also preserves the structure of the RG-I domain. This suggests that this biopolymer may exert a variety of positive effects on different biological targets; therefore, the aim of this study is to evaluate the bioactive properties and structural characteristics of IntegroPectin through complementary experimental and computational approaches. Its ability to modulate specific signaling pathways, along with its antioxidant, anti-inflammatory, and antiproliferative properties, makes IntegroPectin a promising bioactive molecule for further investigation aimed at developing new therapeutic and nutraceutical strategies. This thesis fully aligns with the goals of sustainable development, exploring the valorization of agricultural by-products in various applications.| File | Dimensione | Formato | |
