Individual fat cells/adipocytes store excess dietary fat and energy (triglycerides) in the adipose tissue. Adipocytes and triglycerides are unloaded when lipoprotein lipase on lipid (containing lipoproteins) is sent out from the liver and into the adipose tissue. Circulating lipoproteins also transport lipids in the blood stream. Adipose tissue can also store excess energy, this comes from an over consumption of carbs. Body fat will increase when this happens for several days. Glucose will enter the adipose tissue where it is under the influence of insulin. Then it is stored as triglycerides when synthesised into fat. However, this is more likely when insulin levels are increased. Most glucose is taken into the tissues which is used as fuel and then the glucose will enter the adipose tissue and contribute to the storage of fat. The distribution of the adipose tissue can be influenced by gender, genetics and also hormonal dominance.
Right... that's it!
Seriously, I'm achy all over and done ridiculous amounts of revision which has made my M.E. worse - just hope I can function in the morning. Apologies for the frequent posting, it will now stop!
Good night all x

Nutrition - Vitamins
There are a group of organic compounds containing carbon that vitamins consist of. These are needed for normal metabolism and normal growth. Eating some animal products/plants are ways to to obtain vitamins in your diet as all vitamins are made by plants.
From the action of bacteria in our GI tract, we can synthesise some B vitamins and some K vitamins ourselves. B vitamins include riboflavin and biotin.
There are also inactive vitamins (pro-vitamins e.g. beta-carotene) that can help our bodies to assemble small amount of certain vitamins. Beta-carotene cane be found in dark green and yellow vegetables. In the right circumstances, our bodies can make vitamin A. However, vitamin A needs to be found from elsewhere as the vitamin A in beta-carotene doesn't produce enough.
Fat soluble vitamins can only be absorbed, transported and used when fat is there. These vitamins are A, D, E and K. There is a large lack of fat-soluble vitamins when a diet is low in fat which can result in a person becoming ill. Any lack of vitamin A means the body will not be able to produce hormones that are necessary such as oestrogen, cortisol and testosterone.
Water soluble vitamins are absorbed, transported and used in water. These vitamins are B and C. They have an effect in the cells as they are absorbed along the digestive tract however, these vitamins can't be stored in the body in large amounts. These vitamins are essential for our daily diets to avoid becoming ill. Deficiency will occur when refined simple carbs are a large part of our daily diets. This is because it leads to an excess of sucrose.
Next up will be the purposes and sources of all the vitamins. :)
