This microspectrophotometric (MSP) study has confirmed that goldfish, acclimated under a certain light and temperature regimen, possess mixtures of porphyropsin and rhodopsin in their rod outer segments. Moreover, the MSP spectra from the red, green and blue cones of these acclimated goldfish also shifted to shorter wavelengths from spectra of pure 3-dehydroretinal based visual pigments. Thus, ...

Cinerarin, the anthocyanin isolated from the blue flowers of garden cineraria, S. cruentus by Yoshitama et al. [1, 2], was identified as dicaffeylated delphinidin 3,7,3'-triglucoside on the basis of the chemical evidences and its extraordinary sta­ bility in a neutral aqueous solution was also point­ ed out. Goto et al. [3] established its complete structure as malonyltricaffeyl delphinidin-tet...

PURPOSE To describe unusual macular abnormalities in a family with blue cone monochromacy (BCM, or X-linked incomplete achromatopsia) and deletion of about 9.5 kb comprising part of the red pigment gene and the region upstream of the red pigment gene. METHODS The molecular structure of the red and green pigment genes and the locus control region (LCR) upstream of the red gene were studied for...

Red pigments with bright colors were widely used in ancient Chinese painted pottery, books, antiques, calligraphy, and paintings. Herein, red of traditional paper notes investigated by non-invasive optical technology order to enrich the historical knowledge base. The results laser Raman spectroscopy tests on five clearly identified inorganic mineral including ocher cinnabar. Infrared measuremen...

1. It was found that when hanging drops of whole blood, drawn from a rabbit, were subjected to irradiation from certain light sources, a striking degeneration of the white and of the red cells occurred. In this degeneration of the red cells there was (a) a preliminary period of 15-30 minutes during which no effect was noted; (b) following this, there was a period during which the cells swelled ...

Chlorophyll can be chosen as the fundamental pigment of life. Related to it is protoheme, the red pigment of blood. These substances are found to be biosynthesized from the same parent substance called uroporphyrinogen-III. This paper covers research over a period of 19 years, which has gradually revealed the details of Nature's pathway to uroporphyrinogen-III.

The secretion from the hippopotamus’ skin changes its color from colorless to red, and then brown by polymerization of its pigments. The responsible pigments for the coloring reaction were isolated and denoted as hipposudoric acid (the red pigment) and norhipposudoric acid (the orange pigment). The syntheses of these pigments and the related derivatives were performed, and the latter were of us...

In this article, we report original data on the designation of the primers for full-length cDNA amplification and the internal cDNA amplification of red color-related pigment-binding protein derived from shrimp shell. Data on the color shifts of different soluble proteins under 100 °C 10 min heat treatment and the effects of heating temperatures (from 30 to 100 °C) on the color changes of crude...

Monascus spp. namely Monascus sanguineus was isolated from pomegranate (Punica granatum). In this study, the isolated M. sanguineus was compared with M. purpureus MTCC410 procured from MTCC Chandigarh, India for optimising the red pigment yield. It was observed that both strains had produced maximum red pigment on the 16 day of incubation (21.9 CVU/ml for M. sanguineus & 16.9 CVU/ml for M. purp...

Abstract: Auto-ignited gel combustion process has been used for producing a red hematite-zircon based pigment. The combustible mixtures contained the metal nitrates and citric acid as oxidizers and fuel, respectively. Sodium silicate (water glass) was used as silica source for producing zircon phase. X-Ray Diffractometery, Electron Microscopy and Simultaneous Thermal Analysis were used for ...
