Vitamin K: Importance and Deficiency Vitamin K is a fat-soluble vitamin necessary for blood coagulation. It can be obtained from green leafy vegetables, liver, and gut bacteria. Vitamin K deficiency can lead to bleeding disorders.
Metabolism of Vitamin K "Carbohydrate polysaccharides monosaccharides" are broken down into "proteins polypeptides amino acids", which are then metabolized into triglycerides in the pancreas. Malabsorption syndrome can hinder the absorption of triglycerides and fat-soluble vitamins like vitamin K.
Clinical Uses of Vitamin K Vitamin K can be used to treat bleeding diathesis caused by vitamin K deficiency. It also helps boost bone calcification and prevent soft tissue calcification. Vitamin K is a cofactor for carboxylation and oxidative phosphorylation.
Molecular Biology Basics "DNA replication" refers to the process of going from DNA to another DNA, while "transcription" is the process of going from DNA to RNA. Reverse transcription occurs when going from RNA back to DNA, which is not present in humans but found in HIV virus. Translation involves converting RNA into proteins, followed by post-translational modifications such as trimming or adding/removing components. Examples include collagen modification and gamma carboxylation facilitated by vitamin K.
