which components keeps the soft skin and supple and lubricate joints
Answers
Answer:
Explanation:
Protein
Your body turns the proteins you eat into building blocks called amino acids and reuses them to make other proteins, including the collagen and keratin that form the structure of skin. Amino acids also help slough off old skin.
Some amino acids are antioxidants that protect skin cells against UV rays and from "free radicals" made when your body breaks down certain foods or is around cigarette smoke.
Vitamin A
Both the upper and lower layers of skin need vitamin A. It seems to prevent sun damage by interrupting the process that breaks down collagen. Since it's an antioxidant, it may give your skin some protection against sunburn (although not as much as wearing sunscreen). It helps the oil glands around your hair follicles work and may also help cuts and scrapes heal, especially if you're taking steroids to reduce inflammation.
Without enough vitamin A, your skin might get dry and itchy or bumpy.
Vitamin C
Think "C" for collagen: This vitamin helps the twisted web of protein hold its shape. It's also a powerful antioxidant, protecting you from free radicals and possibly lowering your chance of skin cancer. Low levels of vitamin C can cause easy bruising and bleeding gums, as well as slower-healing sores.
