People with diseases that result in the malabsorption of which nutrient are at risk for a vitamin d deficiency?
grigory [225]

Inadequate dietary vitamin D or its deficiency leads to malabsorption of calcium. Nutritional disorder leads to the rare disease rickets, which causes bones to become soft and bend in children. In adults, vitamin D deficiency leads to osteomalacia, which causes weak bones, bone pain and muscle weakness.

The body needs vitamin D to properly absorb calcium and phosphorus from the diet. However, keeping the right quantities of calcium and phosphorus in bones is challenging when vitamin D levels are low.

The two sources of vitamin D are-

  • Natural sunlight
  • Foods such as fish oil, Egg yolk and fatty fishes like salmon and mackerel

There are other disease conditions which lead to poor absorption of vitamin D-

  • Inflammatory bowel disease
  • Celiac diseases
  • Kidney problems

Explain the meaning of the symbols as they are used in this expression.
Dmitrij [34]

Answer:

  • A, B, C and D are: elements or molecules
  • A and B are: reactants
  • C and D are:  products

Explanation:

The expression "A + B <--> C + D" represents a chemical equation. A chemical equation represents the "mixture" of molecules or elements that will react and form other molecules and elements, so we can say that A, B, C and D represent molecules or elements.

But not only that. In a chemical equation, the elements and molecules that are before the symbol "<-->" represent the reagents in the equation. Therefore, A and B are the reagents. The elements or molecules found after the symbol "<-->" are the products of the reaction. Therefore, C and D are the products.
