There is a person with Albinism. This individual does not produce melanin. Melanin allows for people to be protected from the sun. Since Albinos do not produce this protein they are prone to getting sunburns.What type of molecule is melanin?
A
Carbohydrates
B
Lipids
C
Proteins
D
Nucleic Acids
Explanation: 

Detailed explanation-1: -Several genes give instructions for making one of several proteins involved in producing melanin. Melanin is made by cells called melanocytes that are found in your skin, hair and eyes. Albinism is caused by a change in one of these genes.

Detailed explanation-2: -A small pilot clinical study at the National Eye Institute (NEI) suggests that the drug nitisinone increases melanin production in some people with oculocutaneous albinism type 1B (OCA-1B), a rare genetic disease that causes pale skin and hair and poor vision.

Detailed explanation-3: -Albinism is a genetic disorder, and there is currently no cure. Treatment focuses on getting proper eye care and monitoring skin for problems. Your care team may include your primary care provider, a specialist in eye care called an ophthalmologist and a specialist in skin care called a dermatologist.

Detailed explanation-4: -Oculocutaneous albinism is an autosomal recessive disease caused by the complete absence or decrease of melanin biosynthesis in melanocytes.
