4 Main Organic Compounds

Why do athletes consume protein shakes / powders after a workout? • PROTEIN DOES NOT GIVE YOU ENERGY!!! This is why it is consumed AFTER a workout, not before! • Protein is the basic building material for living things – that includes muscles. • After a workout, there are tiny microscopic tears in the muscles. . . a meal in protein will help rebuild those muscles!

II. A. How does synthesis provide important organic macromolecules using six essential elements? Carbohydrates Monosaccharides are organic compounds made of carbon, hydrogen, and oxygen in a 1: 2: 1 ratio. Many monosaccharides bond together forming a larger compound chain called a carbohydrate (polysaccharide).

II. A. How does synthesis provide important organic macromolecules using six essential elements? Carbohydrates In plants the monosaccharide called glucose (C 6 H 12 O 6) bonds with other glucose molecules again and again to form starch or cellulose. Cracker

II. A. How does synthesis provide important organic macromolecules using six essential elements? Carbohydrates The plant can use starch as food (like the “white” or a potato) and cellulose to build the stem and leaves.

II. How does synthesis provide important organic macromolecules using six essential elements? A. Carbohydrates In animals excess glucose bond together to form a compound (similar to starch) called glycogen which is used for short-term energy storage (or long -term energy use). Glycogen is found in the liver and muscles.

Examples: n Monosaccharide ¨ Glucose ¨ Fructose (in fruit) ¨ Galactose n Disaccharide ¨ Sucrose (table sugar) ¨ Lactose (milk sugar) n Polysaccharide ¨ Starch (in plants) ¨ Cellulose (in plants) ¨ Glycogen (in animals)

Functions of carbohydrates 1. Energy is released when carbohydrates are digested. This is because glucose is used for cellular respiration.

Functions of carbohydrates Monosaccharides (simple sugars) provide an immediate energy source (short-term energy use) Starch and glycogen are considered short term energy storages (or long-term energy use) because these chemicals can be broken down over a period of minutes, hours or days to provide glucose for energy.

Functions of carbohydrates 2. Some carbohydrates are very stable and can be used for structure and support in the cell and body (cellulose in the cell wall of plant cells).

Functions of carbohydrates 3. Carbohydrate chains on the surface of cell membranes are used as identifiers (like name tags).

How does synthesis provide important organic macromolecules using six essential elements? B. Lipids There are several types of lipids, but all contain subunits of glycerol and fatty acids made of carbon, hydrogen, and oxygen. It is different from a carbohydrate because of the ratio and because the smaller units do not link together to form a chemical chain

How does synthesis provide important organic macromolecules using six essential elements? B. Lipids Fats can be saturated (usually solid at room temperature) or unsaturated (usually liquid). Phospholipids also contain a phosphate group and make up most of the cell membrane. Steroids are lipid rings and help regulate the organism through cell communication (act as hormones)

Functions of lipids 1. Because of the numerous bonds and the way the body stores lipids, they can be used as very long-term (weeks, months) energy sources. (energy storage) Ex. Bears accumulate a layer of fat before winter (when food will be less available)

Functions of lipids 2. Fats stored in the body act as insulation and protection for internal organs.

Functions of lipids 3. Some hormones are composed of lipids (steroids).

II. How does synthesis provide important organic macromolecules using six essential elements? A. Nucleic Acids Nucleotides are compounds made up of carbon, hydrogen, oxygen, nitrogen and phosphorus. Many nucleotides bond together to make up a long chain called a nucleic acid. There are two basic types of nucleic acids:

II. How does synthesis provide important organic macromolecules using six essential elements? DNA is a double chain of nucleotides found in all living cells. RNA is a single chain of nucleotides that provides the structures needed for the cell to make proteins.

Functions of nucleic acids 1. DNA makes up the genes. Genes determine traits, such as hair color. Genes are passed from parent to offspring.

Functions of nucleic acids 2. DNA controls cellular activities by controlling the production of proteins in response to hormones and other cellular signals.

Functions of nucleic acids 3. RNA is used in the production of proteins.

II. How does synthesis provide important organic macromolecules using six essential elements? D. Proteins (made of CHON) All six essential elements may be used in the production of small subunits called amino acids. There are 20 different amino acids, each with a specific side chain of chemicals. Amino acids bond to other amino acids to form a long chain called a protein. These chains of amino acids fold into a particular shape. The shape of a protein will determine its function.

II. How does synthesis provide important organic macromolecules using six essential elements? Hemoglobin is a protein shaped to hold oxygen for transport through the bloodstream.

II. How does synthesis provide important organic macromolecules using six essential elements? A group of proteins called enzymes are shaped to fit and react with specific molecules.

Functions of proteins 1. Some proteins, called pigments, absorb and reflect light. They also create color by reflecting light. ¨ Ex. Chlorophyll absorbs light to gather energy for photosynthesis, and reflects the color green

Functions of proteins 2. Some proteins are constructed by cells to bind with and inactivate foreign particles in the body. These are called antibodies.

Functions of proteins 3. Proteins may form structures in an organism – such as keratin (a protein) in hair and nails. Protein also makes muscle

Functions of protein 4. Some proteins are used for transport through the cell membrane or in the bloodstream (ex. hemoglobin)

Functions of protein 5. Some proteins are used for communication between cells. These may be hormones (insulin) or neurotransmitters. Insulin is secreted by the pancreas and is required by the cells of the body in order for them to remove and use glucose from the blood. Insulin can be used to treat diabetes.

Functions of protein 6. Enzymes (a special class of protein) act to speed up chemical reactions, helping to maintain homeostasis.
