Hey everyone. I know last weeks blog was very short and boring. I was tired when I did my post and I am sorry. OK so we did a lab this week, and I took a test on which I got a 95%. The lab was on differrent types of macromolecules and which solutions help to find them. I really enjoed this lab because we got to use chemicals. I really need to work on asking question on tests because I have gotten bad grades on several tests because I didn’t ask questions about things I didn’t understand.

Here are some definitions.

Lipids- Lipids are a wide-ranging group of organic compounds found in all living organisms, including humans, plants, and animals. Lipids are the body's reserve supply of energy. Unlike other organic compounds, lipids are soluble in alcohol, ether, and other organic substances but not in water.

Proteins- Proteins are compounds composed of carbon, hydrogen, oxygen, and nitrogen, which are arranged as strands of amino acids. They play an essential role in the cellular maintenance, growth, and functioning of the human body. Serving as the basic structural molecule of all the tissues in the body, protein makes up nearly 17 percent of the total body weight. To understand protein's role and function in the human body, it is important to understand its basic structure and composition.

Carbohydrates- Carbohydrates are compounds that consist of carbon, hydrogen, and oxygen, linked together by energy- containing bonds. There are two types of carbohydrates: complex and simple. The complex carbohydrates, such as starch and fiber, are classified as polysaccharides. Simple carbohydrates are known as sugars and they are classified as mono- or disaccharides, depending on the number of sugars present. Monosaccharides consist of only one sugar; disaccharides have two sugar molecules bonded together.

Glucose-Glucose is a carbohydrate, and is the most important simple sugar in human metabolism. Glucose is called a simple sugar or a monosaccharide because it is one of the smallest units which has the characteristics of this class of carbohydrates. Glucose is also sometimes called dextrose. Corn syrup is primarily glucose. Glucose is one of the primary molecules which serve as energy sources for plants and animals. It is found in the sap of plants, and is found in the human bloodstream where it is referred to as "blood sugar". The normal concentration of glucose in the blood is about 0.1%, but it becomes much higher in persons suffering from diabetes.
