8 Questions
Which nutrient is mostly found in combination with oxygen as phosphate and is a major component of bone structure and soft tissues?
Phosphorus
What is the recommended dietary allowance (RDA) for phosphorus in milligrams per day for individuals 18 years and older?
550-950
What are some food sources of phosphorus?
Milk, yogurt, cheese, egg, beef, chicken, turkey, salmon, whole grain bread, white bread
What are some metabolic functions of phosphorus in the body?
Structural role in bone and phospholipids, DNA component, pH maintenance, energy storage, activation of enzymes
Explain the role of phosphorus in the body's metabolic functions and structure.
Phosphorus occurs as hydroxyapatite in bone, is a major component of most biological membranes, important for lipid transport, helps maintain pH balance, acts as a source of energy storage in ATP, and is involved in the activation of enzymes through phosphorylation.
What are the functions of phospholipids in the body and where are they found?
Phospholipids are a major component of most biological membranes and are important for lipid transport.
What is the passive and active regulation involved in the absorption and metabolism of phosphorus in the body?
Passive regulation involves concentration-dependent absorption, while active regulation is vitamin D-dependent absorption.
What are some potential effects of phosphorus deficiency and toxicity in the body?
Phosphorus deficiency is rare but can lead to hypophosphatemia, while toxicity can have adverse effects on the body.
