It is a strongly coloured pigment found in plants and fruits. Examples of these foods are carrots, pumpkin, sweet potato, and spinach It is also available as a dietary supplement as pro-vitamin A. The average human intake is between 2 and 7 mg per day. The common results of excess B Carotene is a conspicuous tint of orange in the skin

Structure of keratin?
Alpha keratin has alpha helix structure and beta keratin has beta pleated sheet structure.
What is Alpha and beta keratin in hairdressing?
Keratin is a tough, fibrous protein. There are two types of keratin: alpha- and beta-keratin. Alpha-keratin is softer and is found only in mammals.
What does term beta keratin mean?
Beta keratin is a type of structural protein found in the skin, feathers, and scales of reptiles and birds. Unlike alpha keratin, which is present in mammals' hair and nails, beta keratin has a more rigid and stable structure, contributing to the protective and water-resistant properties of these animals' integumentary systems. This protein plays a crucial role in the evolutionary adaptations of reptiles and birds to their environments.
Carotene and keratin are same?
No. Carotene is a pigment. Beta-carotene is a form of Vitamin A. Keratin is a protein which makes up hair and fingernails. http://en.wikipedia.org/wiki/Keratin
B physical effects of styling long hair?
In the natural unstretched state the hair is Alpha Keratin and when the hair has been styled in the unnatural state it is beta keratin. When blow drying for example the keratin in the alpha keratin is changed to beta keratin, causing the hair to temporarily in its new shape. Once the hair takes in moisture from the atmosphere or becomes wet, it reverts back to the normal state
How do you beat Beta Keratin in Mario and Luigi Bowser's inside story?

How does styling techniques affect the hair structure including beta keratin and alpha?
Styling techniques, such as heat application and chemical treatments, can alter the hair structure by affecting the protein composition, including alpha-keratin and beta-keratin. Alpha-keratin, which is more prevalent in human hair, provides elasticity and strength, while beta-keratin contributes to the hair's rigidity and structure. Excessive heat or harsh chemicals can denature these proteins, leading to weakened hair, increased porosity, and potential damage. Proper care and protective styling can help maintain the integrity of these keratins and overall hair health.
Which of these proteins in mammals show only primary and secondary structures?
Collagen and keratin are examples of proteins in mammals that primarily exhibit only primary and secondary structures. Collagen is known for its triple helix structure, while keratin is a fibrous protein that forms alpha-helices and beta-sheets.
How does heat affect alpha and beta keratin?
Heat can denature keratin proteins, altering their structure and function. This can lead to changes in the physical properties of the hair or skin, such as reduced strength and elasticity. Excessive heat exposure can also break down keratin bonds, causing damage to the integrity of the hair or skin.
Is Minecraft beta out yet?
It depends on what you mean. If you mean when beta is finished, it will be somewhere near 11/11/2011. But if you mean the beta 1.7.3 (that's the beta version when this was answered), then yes.
What does it mean when it say beta full?
full beta
What does alpha keratin mean?
alpha can be translated as the letter "A" in the greek alphabet, but also used as first. keratin are a family of fibrous structural protein
