Vit B1

About Vit B1

Physiological functions: Thiamine pyrophosphate is a coenzyme and the active form of vitamin B. It functions as coenzyme in decarboxylation of a-keto acid and in Hexose Monophosphate shunt.
Deficiency symptoms: In severe vitamin B1 deficiency beriberi develops. It is of two types:
a) Wet beriberi
b) Dry beriberi
Wet beriberi: In this the symptoms are related to the cardiovascular system and they are palpitations, tachycardia, dyspnoea, ECG changes, oedema, and high output cardiac failure.
Dry beriberi: The symptoms and signs are related to the Nervous system. The main features are peripheral neuritis, hyperaesthesia (localized areas) or anaesthesia, there is gradual loss in muscle strength, wrist drop, poor memory, depression, lack of initiative and anorexia.
Mechanism of Action of Vit B1
Thiamine exerts it`s action by influencing carbohydrate metabolism. It combines with ATP to form thiamine pyrophosphate in the body. Thiamine pyrophosphate acts as a coenzyme for carbohydrate metabolism, decarboxylation of ketoacids, and hexose monophosphate shunt. It also have plays some role in neuromuscular transmission.
Pharmacokinets of Vit B1
Absorption: Well absorbed orally.
Distribution: Widely distributed in the body. It is also distributed in to breast milk.

About Vit B2
N/A
Mechanism of Action of Vit B2
Riboflavin exerts it`s action by influencing metabolic reactions. Riboflavin functions in the forms of flavin adenine dinucleotide (FAD), and flavin mononucleotide (FMN) which are coenzymes for flavoproteins involved in many oxidation-reduction reactions. Both FMN and FAD play a vital metabolic role in numerous tissue respiration systems. Riboflavin also directly involves in maintaining erythrocyte integrity.
Pharmacokinets of Vit B2
Absorption: Well absorbed orally; bioavailability increases when administer along with food.
Distribution: Widely distributed in the tissues and limited amount is stored in the liver, spleen, kidneys, and heart. It crosses the placenta and also secreted in to the breast milk.
Metabolism: Phosphorylated in the intestine, liver and other tissues to FMN and metabolized in to FAD the liver.
Excretion: Larger doses are excreted unchanged in urine.

Vit B3

About Vit B3
N/A
Mechanism of Action of Vit B3
Niacin refers to Nicotinic acid as well as Nicotinamide which exerts it`s action by influencing metabolic reactions. It is converted in to coenzymes Ncotinamide adenine dinucleotide (NAD) and it`s phosphate Ncotinamide adenine dinucleotide phosphate (NADP) involved in oxidation reduction reactions. These pyridine nucleotides act as hydrogen acceptors in the electron transport chain in tissue respiration, glycolysis, and fat synthesis. Nicotinic acid in high doses has vasodilator effects and also improves lipid profile; reduces serum cholesterol, raises HDL level, lowers VLDL, and LDL levels.
Pharmacokinets of Vit B3
Absorption: Well absorbed orally, Distribution: Widely distributed in the body, and also secreted in to breast milk, Modest amounts are stored in liver, Metabolism: Metabolized in to active metabolites in liver, Excretion: Extra drug is excreted through urine.
