What are the classification of vitamins?
Vitamins are generally classified as water-soluble vitamins and fat-soluble vitamins.
- Fat-Soluble Vitamins. Vitamin A, D, E and K are fat-soluble.
- Water-Soluble Vitamins. Vitamins in B-group and vitamin C are water-soluble and cannot be stored in our bodies as they pass with the water in urine.
What is vitamins and write its classification?
Vitamins can be classified into two groups. This classification is on the basis of the vitamins solubility in water or fat. These are the vitamins that are soluble in fat and oils but are completely insoluble in water. Examples of these vitamins are Vitamins A, D, E, and K.
What are the classification of vitamins and minerals?
Vitamins and minerals are micronutrients required by the body to carry out a range of normal functions. However, these micronutrients are not produced in our bodies and must be derived from the food we eat. Vitamins are organic substances that are generally classified as either fat soluble or water soluble.
Who vit a classification?
The different eye signs of vitamin A deficiency (VAD) in children, as graded by the WHO, are: Night blindness (XN) Conjunctival xerosis (X1A) Bitot’s spots (X1B)…Conjunctival xerosis.
| Grade of xerophthalmia | X3A |
|---|---|
| Corneal ulcer/ <1/3 cornea | |
| Peak age group (years) | 1–4 |
| Type of deficiency | Severe acute deficiency. Blinding |
What are the classification of vitamin A deficiency?
Vitamin A deficiency can be defined clinically or subclinically. Xerophthalmia is the clinical spectrum of ocular manifestations of vitamin A deficiency; these range from the milder stages of night blindness and Bitot spots to the potentially blinding stages of corneal xerosis, ulceration and necrosis (keratomalacia).
What are the 2 classifications of minerals?
There are two kinds of minerals: macrominerals and trace minerals. You need larger amounts of macrominerals. They include calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur. You only need small amounts of trace minerals.
What functional groups are in vitamin A?
Vitamin A exists in three forms that differ in the oxidation state of the terminal functional group: the stable alcohol retinol, the aldehyde retinal, and retinoic acid. All three compounds have important biological functions.
What are the properties of vitamin A?
Vitamin A (retinol, retinoic acid) is a nutrient important to vision, growth, cell division, reproduction and immunity. Vitamin A also has antioxidant properties.
What are the properties of vitamins?
Some vitamins are fat-soluble; the others are water-soluble. The water-soluble vitamins (C, thiamin, riboflavin, pyridoxine, biotin, pantothenic acid, folate, B12) tend to have one or more polar or ionizable groups, whereas the fat-soluble vitamins (A, D, E, and K) have predominantly aromatic and aliphatic characters.
How are vitamins classified name the vitamin responsible for the coagulation of blood?
Vitamin K is responsible for the coagulation of blood.
What are the 5 classifications of a mineral?
The broadest divisions of the classification used in the present discussion are (1) native elements, (2) sulfides, (3) sulfosalts, (4) oxides and hydroxides, (5) halides, (6) carbonates, (7) nitrates, (8) borates, (9) sulfates, (10) phosphates, and (11) silicates.
What are the main mineral groups and how are they classified?
Minerals are grouped by their chemical composition. Silicates, oxides, sulfates, sulfides, carbonates, native elements, and halides are all major mineral groups.
