Pigment

test is a blood test which reveals the average blood glucose levels over a period of about 8 to 12 weeks or 2 to three months, which is the lifetime of a average red blood cell. Haemoglobin is the color pigment in the red blood cells that carries oxygen around the body. Glucose attaches to this pigment to make a "glycosylated haemoglobin" molecule called haemoglobin A1C or HbA1C. Due to this fact, the higher the haemoglobin A1C or HbA1c percentage, the higher the glucose in the blood.on…

teeth to be stained faster due to the dentin being exposed. Wine may have really nice benefits for your body, like relaxation and benefits for one’s heart, but wine has no benefits whatsoever for the teeth. There are pigments called “anthocyanin” in wine and grape juice. These pigments allow the wine and/or grape juice to really leave a mark on teeth if someone were to drink often. However, anthocyanin has also been proved to be quite beneficial to the human body. Berries, slushies, popsicles,…

emitted by the sun. All bands of UV radiation damage collagen fibers and accelerate aging of the skin. Both UVA and UVB destroy vitamin A in skin, which may cause further damage. UVB light can cause direct DNA damage. In defense, our body releases a pigment called melanin, which is produced by cells in our skin called melanocytes. Melanin absorbs ultraviolet light and dissipates it as heat. According to Gary Chuang, assistant professor of dermatology at Tufts University School of Medicine says,”…

particles. By making the fat into smaller particles, the fat can be digested. Bile has a composition of: cholesterol, triglycerides, phospholipids, an assortment of electrolytes, water, bile salts, and bile pigments. (Bile salts are mainly cholic and chenodeoxycholic acids while bile pigment consists mostly of bilirubin.) Some accessory organs associated with the small intestine play a role in bile production, storage, and concentration. The livers digestive function is to produce bile for…

Pottery was generally made of clay found in the Nile River. In upper Egypt, people used marl clay to create pottery. One of the types of pottery made were covered in a substance called red ochre, an iron oxide coloring known as a pigment that was naturally found in Egypt. They would crush the red ochre to a powder form and use it as a coloring for the pottery. Sometimes it covered the entire item and sometimes they used it for decorations. They also used other crushed minerals, mixed…

Mercury Sulfide (Cinnabar) was used as a bright red pigment to Palaeolithic painters, this was to decorate caves in spain and France the metal fascinated people because it was a liquid that would dissolve gold. The ancients used in on a large scale to extract alluvial gold from the sediment of rivers. The…

expected to be eluted after Yellow-Orange Carotene pigments. And the other pigments such as Xanthophylls, which are more polar due to their hydroxyl group, are strongly attracted to Alumina, which would be eluted after Lycopene band. The column should be covered by aluminum foil to prevent Isomerisation of Lycopene by light. A clear orange layer of Lycopene band formed at the beginning of the separation; however there were not enough pigments for collection. The band became more blurred when…

The laser can zap small surface veins to reduce discoloration from excess blood vessels. It can also resurface the skin to get rid of wrinkles and excess pigmentation unless the pigment is too deep under the skin. Bleaching is an alternative treatment your dermatologist might want to try. The bleaching solution is applied to the skin to lighten it when it is dark from excess pigmentation on the surface. Your dermatologist will…

This disease doesn’t just occur on the skins surfaces, but it can appear on the scalp causing spots of white blotches being seen in hair. Vitiligo occurs when there is damage to the melanocytes, which are cells that produce melanin. Melanin is the pigment…

Colour is one of the most pervasive qualities in our human environment and one of the qualities that humans could not live without. Colour is used to be able to allow humans to interact with; such as taking note of the colours chosen for clothes, to check the traffic lights when driving, to choose colours when painting a picture, or to be able to distinguish the food that humans eat by looking at the colour of the food. However, humans who have the capability to see colour; tend to perceive…
