Critical Reviews in Food Science and Nutrition
|August 5, 2022
Summary
Fish and shellfish are vital sources of beneficial carotenoids, offering potent antioxidants like astaxanthin. Further research is needed to understand their bioavailability for human health.
Area of Science:
- Marine Biology
- Nutritional Science
- Biochemistry
Background:
- Carotenoids, natural pigments, offer significant health benefits.
- While plants are a common source, aquatic animals like fish and shellfish provide unique carotenoids.
- Existing research on carotenoids in seafood is extensive but disorganized.
Approach:
- This paper reviews scientific literature on carotenoid content and composition in fish and shellfish.
- It synthesizes data to clarify the current research status and identify future study directions.
- The review focuses on summarizing evidence related to specific research questions.
Key Points:
- Fish and shellfish are rich in complex carotenoids such as astaxanthin, fucoxanthin, fucoxanthinol, and lutein.
- These compounds exhibit strong antioxidant properties, effectively neutralizing reactive oxygen species.
- Carotenoid levels are influenced by factors including genetics, environment, and processing methods.
Conclusions:
- Seafood carotenoids possess potent antioxidant and health-promoting properties.
- Limited data on bioavailability hinders understanding their full health impact.
- This review guides dietary choices and aquaculture for natural carotenoid production.

Red Algae
123
Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...

Osmoregulation in Fishes
50.3K
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Poisson's Ratio
529
Poisson's ratio is a material property that indicates their stress response. It explains the connection between the elongation or compression a material undergoes in the direction of an applied force and the contraction or expansion it experiences perpendicular to that force. When a slender bar is loaded axially, it stretches in the direction of the force and contracts laterally. Poisson's ratio is the negative ratio of this lateral contraction to the axial elongation. The negative sign...

Protein Transport to the Thylakoids
2.3K
Thylakoids are membrane-bound sac-like structures within the chloroplast that serve as sites for photosynthesis. Thylakoid lumen contains many electron transport proteins and is enclosed by a thylakoid membrane rich in the light-harvesting complex. Proteins targeted to the thylakoids are transported as precursors and are sorted by the general TOC/TIC import pathway. Once the precursor reaches the stroma, stromal processing peptidases remove their transit signal and expose thylakoid signal...

Channel Rhodopsins
2.6K
Most organisms use photoreceptors to sense and respond to light. Examples of photoreceptors include bacteriorhodopsins and bacteriophytochromes in some bacteria, phytochromes in plants, and rhodopsins in the photoreceptor cells of the vertebral retina. The light-sensitive property of these receptors is because of the bound chromophores, such as bilin in the phytochromes and retinal in the rhodopsins.
Rhodopsins belong to the family of cell surface proteins called G-protein coupled receptors,...

Photoreceptors and Plant Responses to Light
23.5K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.
