Abstract:

Abstract Carotenoid pigmentation in birds' plumage is considered an honest indicator of phenotypic quality, and thus a target of sexual selection. But carotenoids also fulfill essential physiological functions, and therefore, carotenoids should only appear in plumage if they are in excess of those needed physiologically. We explored the presence of carotenoid-based plumage coloration in columbids and its association with diet and sexual dichromatism using a comparative analysis. We found that carotenoid plumage pigmentation appeared three times independently in doves, and that these events wer

Abstract:

Abstract Birds that use carotenoids to color their feathers must ultimately obtain these pigments from the diet, but they are also capable of metabolically transforming dietary carotenoids into alternate forms that they use as plumage colorants. The genetic and enzymatic control mechanisms underlying carotenoid metabolism are poorly understood. We investigated carotenoid pigments present in the feathers of an aberrantly colored yellow Northern Cardinal (Cardinalis cardinalis) to determine how metabolic pathways may have been altered. Normal red cardinals display four primary keto-carotenoids i

The objective of the present study was to determine the content and bioaccessibility of carotenoids in 104 maize hybrids available at the market. Lutein, zeaxanthin, α- and β-cryptoxanthin, and β-carotene were determined in whole grains and micelles produced during standardized INFOGEST digestibility analysis, and their bioaccessibility was calculated as the ratio of micellar and grain carotenoids. Tested hybrids varied in total carotenoid content, with 34% having total carotenoid content in the range of 15–20 µg/g dry matter (DM) and 41% in the range of 20–25 µg/g DM. The amount of bioaccessi

Abstract:

Cherry tomatoes are rich sources of carotenoids. The carotenoids are known to be precursors of vitamin A and also act as an antioxidant. It is important to visually judge the tomato surface color for higher β carotene content since this is the major provitamin AA carotenoid. Estimation of carotenoids by HPLC (High Performance Liquid Chromatography) and spectrophotometric methods in tomatoes are very expensive and time consuming. Therefore, colorimeters can be used to describe the color and determine the carotenoid content in a relatively easy and inexpensive manner. The objective of this study

Abstract:

A complete determination of the carotenoid composition of the edible aril and mesocarp of Cionosicyos macranthus fruit is reported for the first time. The carotenoids present in the fruit were identified and quantified using high-purity carotenoid standards. The fruit contained several rare carotenoids like zeaxanthin, β-cryptoxanthin, and cryptocapsin epoxides. Various keto-κ end-ring carotenoids, derivatives of their corresponding epoxides, ie cryptocapsin, capsanthin, capsanthin 5,6-epoxide, and capsoneoxanthin, were also identified. The total carotenoid contents for the aril and mesocarp w

Abstract:

The evolutionarily persistent and widespread use of carotenoid pigments in animal coloration contrasts with their biochemical instability. Consequently, evolution of carotenoid-based displays should include mechanisms to accommodate or limit pigment degradation. In birds, this could involve two strategies: (i) evolution of a moult immediately prior to the mating season, enabling the use of particularly fast-degrading carotenoids and (ii) evolution of the ability to stabilize dietary carotenoids through metabolic modification or association with feather keratins.

Abstract:

Carotenoids are lipid-soluble compounds that are present in nature, including plants and microorganisms such as fungi, certain bacteria, and algae. In fungi, they are widely present in almost all taxonomic classifications. Fungal carotenoids have gained special attention due to their biochemistry and the genetics of their synthetic pathway. The antioxidant potential of carotenoids may help fungi survive longer in their natural environment. Carotenoids may be produced in greater quantities using biotechnological methods than by chemical synthesis or plant extraction. The initial focus of this r

Carotenoids are natural isoprenoid pigments that provide leaves, fruits, vegetables and flowers with distinctive yellow, orange and some reddish colours as well as several aromas in plants. Their bright colours serve as attractants for pollination and seed dispersal. Carotenoids comprise a large family of C40 polyenes and are synthesised by all photosynthetic organisms, aphids, some bacteria and fungi alike. In animals carotenoid derivatives promote health, improve sexual behaviour and are essential for reproduction. As such, carotenoids are commercially important in agriculture, food, health
