Which one of the following can be synthesized by Liver ? A)Vitamin – A B)Vitamin – E C)Vitamin – D D)Vitamin – K
Option D) Vitamin K is a group of structurally similar, fat-soluble vitamins that are needed for the posttranslational modification of certain proteins required for blood coagulation and in metabolic pathways in bone and other tissue. This group of vitamins includes two natural vitamers: vitamin K1 and vitamin K2. Populations with an increased prevalence of vitamin K deficiency include those who suffer from liver damage or disease (e.g. alcoholics), cystic fibrosis, or inflammatory bowel diseases, or have recently had abdominal surgeries. The vitamin K - dependent coagulation proteins are synthesised in the liver and comprise factors II, VII, IX, and X, which have a haemostatic role.
