There are 9 water-soluble vitamins in the Vitamin B Complex: (examples: B6 and B12). Also, there are only 4 lipid - soluble (fat or oil - soluble) vitamins: A, D, E, and K.
Vitamin C and B complex are both water soluble (ie hydrophilic), which is why a daily dose is recommended. Your body only uses what it needs in a day, and any excess in your body will be dissolved in water and excreted (this is why your urine is very yellow after taking a B complex, it's the excess B2 - riboflavin that is naturally yellow.) Vitamins A, D, E, and K are all fat soluble (ie hydrophobic). The excess which is not used is stored in adipose tissue (fat cells) until needed. This is where people started saying you'll turn orange if you eat too many carrots: carrots contain beta-carotene which the body turns into vitamin A with bile salts. So it is possible to get too much of the A, D, E, and K (though none are toxic at high levels except vit D - so watch out), but it is silly to take tablets with large amounts of vitamins B and C because you'll just excrete it!
Water-soluble vitamins dissolve easily in water and, in general, your body can readily excrete them in urine. Because you can't readily store them, you need to consume them more consistently. Bacteria synthesize many types of water-soluble vitamins.
vitamins are divided into two classesFat-Soluble VitaminsFat-soluble vitamins include vitamin A, D, E and K. Because fat-soluble vitamins are stored for long periods, they are not needed every day in the diet. However, they are very necessary for important functions, such as blood clotting and calcium absorbency. If you are concerned about getting too much A, D, E or K, remember that relying on a healthy diet as your source of consuming vitamins can ensure healthy intake levels. Water-Soluble VitaminsWater-soluble vitamins are vitamin B1--thiamin, B2--riboflavin, B6, B12, C, folic acid and niacin. Many people worry about cooking out vitamins in vegetables. Often, those vitamins are the water-soluble type. They are easily destroyed through certain storage conditions and cooking techniques. These vitamins are found commonly in many foods, such as grains, meats, greens, legumes and beans. These vitamins are not stored within your body, so you need daily replenishment.
Vitamins are classified into two main categories: water-soluble vitamins and fat-soluble vitamins. Water-soluble vitamins include the B-complex vitamins and vitamin C, which dissolve in water and are not stored in the body. Fat-soluble vitamins include vitamins A, D, E, and K, which are stored in the body's fatty tissues and liver. This classification helps in understanding their absorption and storage in the body.
Vitamins are typically divided into two categories: water-soluble vitamins (such as Vitamin C and B-complex vitamins) and fat-soluble vitamins (such as Vitamins A, D, E, and K). Water-soluble vitamins are not stored in the body and need regular intake, while fat-soluble vitamins are stored in the body's fatty tissues and liver.

2 classes. Water soluble and Fat soluble
Fat soluble vitamins travel in fats within the body. This means that high amounts of them which are not used are stored within your fat reserves. If this happens you can have poisoness effects over time. Water soluble vitamins leave the body through excretion.
Vitamins are classified as either water-soluble or fat-soluble. In humans there are 13 vitamins: 4 fat-soluble (A, D, E, and K) and 9 water-soluble (8 B vitamins and vitamin C). Water-soluble vitamins dissolve easily in water and, in general, are readily excreted from the body, to the degree that urinary output is a strong predictor of vitamin consumption. Because they are not readily stored, consistent daily intake is important. Many types of water-soluble vitamins are synthesized by bacteria. They remain active because vitamins are a certain set of compounds that the body converts to what it needs once ingested. If you care about being healthy do yourself a favour and don't drink Vitamin Water at all. It has almost as much sugar in it as coca cola (and is made by them too). Drink tap water and get your vitamins from eating fresh fruit and vegtables. If you really feel the need to take vitamin supplements buy soem from a pharmacy.
Animal fats are formed by triglycerides. Lipids include many things including fats, waxes, vitamins that are fat-soluble, and are responsible for storing energy.
Fats
There are many compounds that are soluble in oil but not water. These compounds include alkanes and other organic molecules that are mostly nonpolar. Even long-chain alcohols are soluble in oil but not water, though one part of the molecule is polar.
