Using three antibodies to visual pigments (monoclonal antibodies COS-1 and OS-2, and a polyclonal anti-opsin serum), four different types of cone cells could be distinguished in the red area (dorsoposterior part with the highest density of cones) of the pigeon retina. Both members of the double cone and the single cone with the red oil droplet were labelled with our monoclonal antibody COS-1 (t...

In this article, the effect of potassium on structure and anticorrosion properties of zinc phosphate pigments has been investigated. The co-precipitation method was selected as synthesis method of potassium zinc phosphate pigment. Then the synthesized pigment was characterized by x-ray diffraction XRD, Fourier transform infrared FTIR and Raman spectroscopy. Morphology of the powders was investi...

Monascus purpureus is known to produce pigment molecules. The pigments were extracted from M. fermented rice. In-vitro antioxidant effects of observed and presumed alleviate oxidative stress related atherosclerosis effect in rats fed with high fat diet (HFD) for 14 weeks. formation lipid peroxide due the oxidation serum was higher HFD. While, feeding rice (groups III-V) significantly lowered (2...

A variety of vegetable and fruit derived food oils are considered beneficial for human health due to their content functional components including positive effects in cardiovascular system. In addition the favorable ratio unsaturated versus saturated fatty acids, some these include also other compounds such as vitamins, minerals, pigments, enzymes phenolic compounds. Particularly polyphenols ha...

Marine algae have gained substantial attention from various scientific and commercial fields. The reason behind its importance is due to the rich source of bioactive compounds like proteins, carbohydrates, lipids, other pigments. algae-derived carrageenans polysaccharides are used in food, medicine, cosmetic items, gelling, emulsifying, stabilizing agents. carrageenan has also photoprotective a...
