What do we mean by crystalline?

What are crystallins in the eye?
Crystallins are the predominant structural proteins in the lens that are evolutionarily related to stress proteins. They were first discovered outside the vertebrate eye lens by Bhat and colleagues in 1989 who found alphaB-crystallin expression in the retina, heart, skeletal muscles, skin, brain and other tissues.
What does the protein crystallin do?
a-Crystallin is a major lens protein, comprising up to 40% of total lens proteins, where its structural function is to assist in maintaining the proper refractive index in the lens. In addition to its structural role, it has been shown to function in a chaperone-like manner.
What causes protein deposits in the eye?
Protein deposits that are visible to the naked eye are most often a result of denaturation. While even a visibly clean lens may still have protein deposits, only denatured deposits increase the possibility of clinical symptoms associated with contact lens deposits.
What is crystalline salt?
Sodium chloride crystals are cubic in form. Table salt consists of tiny cubes tightly bound together through ionic bonding of the sodium and chloride ions. The salt crystal is often used as an example of crystalline structure. When viewed under strong magnification, all sodium chloride is crystalline.
Do skin cells have crystallin?
The crystallin gene is not present in skin cells. Skin cells have the crystallin gene but do not express it. Skin cells use different DNA for their genes.
Are eye floaters protein?
Most floaters are small flecks of a protein called collagen. They’re part of a gel-like substance in the back of your eye called the vitreous. As you age, the protein fibers that make up the vitreous shrink down to little shreds that clump together. The shadows they cast on your retina are floaters.
How does the body produce crystallin?
αA-Crystallin apparently originated from the multigene small heat shock proteins (HSPs). The HSPs are induced upon stress and evolved in all eukaryotes by gene duplication and the subsequent sequence divergence that allows adaptation to novel functions, such as lens constituent.
How do I get rid of protein deposits in my eye?
Protein buildup on contact lenses can cause blurred vision and discomfort. Proper handling of contact lenses and using an enzymatic cleaner on your lenses can eliminate protein deposits. For contact lens users who have continued problems with protein buildup, daily disposable lenses may be the solution to the problem.
What causes cataract in your eyes?
Most cataracts develop when aging or injury changes the tissue that makes up the eye’s lens. Proteins and fibers in the lens begin to break down, causing vision to become hazy or cloudy. Some inherited genetic disorders that cause other health problems can increase your risk of cataracts.
