Vitamin B5: Functions and Sources

Vitamin B5 is a water soluble vitamin, also known as pantothenic (Greek: pantos- everywhere) Acid. It is one of the most widely distributed vitamins found in plants and animals. Pantoic acid and beta-alanine combine together to form pantothenic acid.

Functions of Vitamin B5 The functions of B5 are exerted through coenzyme A or CoA. Coenzyme A is a central molecule involved in all the metabolisms (carbohydrate, lipid and protein). Like other B vitamins, it is involved in chemical reactions of energy production.
Important roles of vitamin B5 in body Synthesis of fatty acidsRed blood cells formationFormation of stress and sex related hormone in adrenal glandMaintaining health of the nervous systemHelps in the utilization of Riboflavin ( vitamin B2)Maintaining healthy digestive tractLowers cholesterol levelsRecommended dietary allowance of vitamin B5 Up to 6 months of age, 1.7 mgFor 7-12 months, 1.8 mgFor 1-3 years of age, 2 mgFor 4-8 years of age, 3 mgFor 9-13 years of age, 4 mgAbove 14 ye…

Vitamin B12 is a water soluble vitamin. It is known as cobalamin because it contains mineral cobalt. it is a unique vitamin, synthesized by only microorganisms and not by animals and plants. It is required for Red blood cell formation, myelin synthesis around neurons, DNA synthesis, and energy production.

How Much Vitamin B12 Required? Up to age of 6 months 0.4 mcgFor 7-12 months of age, 0.5 mcgFor 1-3 years of age, 0.9 mcgFor 4-8 years of age, 1.2 mcgFor 9-13 years of age, 1.8 mcgIn adults (14+) 2.4 mcgFor pregnant female 2.6 mcgAnd for lactating mother 2.8 mcgSources of Vitamin B12 Foods of animal origin are the only natural sources of vitamin B12.

Vitamins: Definition, Classification, Types, Functions and Sources

Definition:  Vitamins are a group of organic nutrients, required in small quantities for a variety of biochemical functions that, generally, cannot be synthesized by the body and must, therefore, be supplied in the diet.

Classification On the basis of solubility, vitamins are classified into two categories-
1. Lipid soluble vitamins Vitamin AVitamin D (Calciferol)Vitamin EVitamin K 2. Water soluble vitamins Vitamin B1 (Thiamine)Vitamin B2 (Riboflavin)Vitamin B3 (Niacin)Vitamin B5 (pantothenic acid)Vitamin B6 (Pyridoxine)Vitamin B7 (Biotin)Vitamin B9 (Folic acid)Vitamin B12 (Cyanocobalamin)Vitamin C (Ascorbic acid) Lipid soluble vitamins are stored in the body but, water soluble vitamins are eliminated through urine and require high dietary supplementation.
All B vitamins are known together as B complex.

Types and Their Sources 1. Vitamin A There are two types of vitamin A Retinoids and provitamins (Carotenoids). Retinoids comprise retinol, retinaldehyde, retinoic acid (preformed vitamin A…
