What protein, necessary for proper calcium deposition into bone matrix, is activated by Vitamin K found in kale?
Answer
Osteocalcin
Vitamin K functions as a crucial cofactor in the skeletal system by enabling the body to properly utilize calcium. Specifically, Vitamin K is necessary for the activation of osteocalcin, a protein that plays an essential role in bone mineralization. Without sufficient activated osteocalcin, the body cannot effectively deposit calcium into the bone matrix, which can compromise bone density over time. Given that a single cup of raw kale supplies many times the daily requirement of Vitamin K, its consumption is strongly linked to proactive maintenance of skeletal health, surpassing the contribution of staples like milk or eggs in this specific nutrient.
