Bio Chemistry Lesson of the Day


Last night I was talking with a friend and I told her how I am learning that I avoid situations or work quickly to lessen any experience that would get my adrenalin pumping. I don't like drama. I don't like exercise. I have never had this thought before. So being the dutiful researcher that I am I started reading about adrenaline.

Adrenaline is a natural hormone that your body is constantly producing in small doses. Adrenaline is produced in the adrenal glands that are located above the kidneys. In addition to the adrenaline, another hormone very similar to it is also released from the adrenal glands. Nonadrenaline accounts for 20% of the total hormone secreted from the adrenal glands while, the more dominate adrenaline accounts for 80% of the secreted hormones. Together these hormones work to try ot prepare the body to make it more alert and ready for when extra energy and exertion is needed. Once these hormones are released from the adrenal glands and are working their way through the body several things will occur. The adrenaline is in charge of making soem of the smaller blood vessels close up while it makes the blood in the liver and the skeletal muscles wider. By making the less important blood vessels smaller, and opening up the more important blood vessles, a better blood flow is create. With this better blood flow towards the skeletal muscles and liver, the muscles and liver will be able to functin to their highest ability due to the increase in oxygen that they are receiving. Adrenaline is also responsible for the collapse of glycogen to glucose. This chemical change occurs in the liver and with this happening, the sugar level in the blood increases. The nonadrenaline constricts blood vessels too. The difference between the two is that the nonadrenaline constricts almost all the blood vessels while the adrenaline only constricts the less important ones. The two hormones work together to increase the contractions of the heart, which creates a better and stronger blood flow. Another duty in which these two hormones team up to do is increase the amounts of flowing free fatty acids. With these acids just moving free throughout the body, the body can use them anytime it needs to.

What are fatty acids? I hear the word fatty and I associate it with "bad".

Fatty acids are acids produced when fats are broken down. They are considered “good fats.” These acids are not highly soluble in water, and they can be used for energy by most types of cells. They may be monounsaturated, polyunsaturated, or saturated. They are organic, or in other words, they contain both carbon and hydrogen molecules.

Fatty acids are found in oils and other fats that make up different foods. They are an important part of a healthy diet, because the body needs them for several purposes. Fatty acids help move oxygen through the bloodstream to all parts of the body. They aid cell membrane development, strength, and function, and they are necessary for strong organs and tissue.

Fatty acids can also help keep skin healthy, help prevent early aging, and may promote weight loss by helping the body process cholesterol. More importantly, they help rid the arteries of cholesterol build up. Another purpose of fatty acids is to assist the adrenal and thyroid glands, which may also help regulate weight.

There are different types of fatty acids. You have most likely heard of certain types, such as Omega 3. Omega-3 is considered an “essential” fatty acid, as is Omega-6. There is one other, Omega-9, but this type can be readily produced by the body, while the other two types cannot.

Omega-3 and Omega-6 fatty acids are found in fish and certain plants. Since they cannot be produced in the body, they must be ingested in the form of foods or natural supplements. However, it is important to discuss all supplements with your healthcare provider before you begin taking them.

Essential fatty acids are required to retain healthy lipid levels in the blood. They are also necessary for proper clotting and regulated blood pressure. Another important function is controlling imflammation in cases of infection or injury. Essential fatty acids can also help the immune system to react properly. While we tend to think of all forms of “fats” as bad or unhealthy, it is important to realize that certain fats, namely fatty acids, are essential for optimum health.

What is Cholesterol?

Cholesterol is a soft, waxy substance found in all parts of the body. Your body makes some cholesterol, and some cholesterol comes from the food you eat.

Your body needs a little bit of cholesterol to work properly. But too much cholesterol can clog your arteries and lead to heart disease

Cholesterol helps the body produce hormones, bile acid, and vitamine D. Cholesterol moves through the bloodstream to be used by all parts of the body.
