Abstract

Carotenoids are a group of natural pigments, consisting of more than 750 compounds. They are mostly yellow, orange, or red in color, due to the system of conjugated double bonds. This structural element is also responsible for the good antioxidant properties of many carotenoids. Carotenoids have shown numerous biological activities (not only as provitamin A), e.g., preventive properties of fruits and vegetables. As lipophilic compounds, their uptake and storage in the body are dependent on various conditions. In vitro and in vivo data showed stimulating and inhibitory effects of matrix compounds on bioaccessibility and bioavailability of carotenoids.

Abstract

Carotenoids are a group of approximately 600 compounds synthesized by photosynthetic organisms. These pigments are abundant in fruits and vegetables, as well as in certain animal products such as eggs and salmon, being responsible for their colorful appearance. The bioactive properties of certain carotenoids in human health are clear, as some of these compounds have antioxidant properties and serve as the only precursors of vitamin A in nature. The aim of this Special Issue entitled “Carotenoids and Human Health” is to provide the scientific community with an updated perspective of this exciting and growing research area. We compiled 19 papers from some of the most prominent scientists in the carotenoid field, including seven literature reviews and 12 original publication, covering topics such as cancer, obesity, vision, cognitive function, and skin health.

Abstract

Alternative and renewable energy sources already play a very decisive role in the development of human society, helping to fulfill increasing energy demands from both industrialized and underdeveloped countries, as well as economic needs, which must comply with a decarbonized economy, decreasing the energy impact on the global environment. Among these alternative energy sources, fuels such as biodiesel, methanol, and methane are good examples of how the previous design can be achieved, as these fuels can be obtained from renewable sources, used in applications such as transportation systems, electricity generation, fuel conversion, and even for electricity storage, with reduced impact on air emissions. This Special Issue includes papers on new and innovative technical developments or approaches, reviews, case studies, as well as assessment, papers from different disciplines, which are relevant to the optimization of biodiesel, methane/methanol production systems, simultaneously resulting in air quality improvement.
