We conducted some experiments to test the presence of biomolecules Ex: 1. Starch test We had to see which food doesn’t have any starch from: bread, potato, orange, and apple. We dropped three drops of iodine solution. Results showed that orange doesn’t have any starch. 2. Protein test We had to see which food had the most protiens out of : egg white solution, milk, soda. We conducted an experiment to see which food had the most protein. Our result was egg white solution. 3. Glucose test. Which food has the most glucose: water, soda, milk, oil. Our experiment was about which food has the most glucose. We said that soda had the most glucose. 4. Lipids test We had to figure out which food had to have the most lipids out of: water, soda, milk, and oil. We had to figure out what food had the most precentage of lipids. Oil was our answer. 5. Extended questions We answered some extra questions about our experiment.

We conducted a lab experiment on water properties. Water is everywhere, each molecule of water is made up of 2 hydrogen atoms and 1 oxygen atoms Water is polar because the oxygen molecule has a slightly negative charge and the hydrogen molecule has a slightly negative charge. In one of the experiments we conducted it was about capillary action we used a beaker of blue water, an empty beaker, paper towel, narrow and wide drinking straws a beaker of green water than we Place the beaker of blue-colored water beside the empty beaker and made a simple paper towel bridge to connect the beakers. The results were the colored water moved from the first beaker to the other
Saturated It has no double bonds (C=C) in the fatty acids. The structure has the maximum number of hydrogens. It has long straight chains It has solid at room temperature Contribute to cardiovascular disease as they can increase the bad cholesterol LDL. Found in many animal products such as butter, cheese, whole milk, ice cream, cream and fatty meats. Unsaturated It has one double bond (C=C) in the fatty acids. The structure has fewer hydrogens. It has bent chains. It is liquid at room temperature. Healthier than saturated fats because they can help lower blood cholesterol unless they are trans fats in that case it is not healthy. It is found in avocados peanut butter, nuts, seeds and vegetable oils such as olive oil, canola oil, peanut oil, sesame oil and sunflower oil.
Difference between good and bad cholesterol: Cholesterol belongs to the steroid family of lipid. Cholesterol is the most abundant steroid in the body. The cholesterol in your blood comes from two sources: the foods you eat like meat and dairy products and your liver. Your liver makes all the cholesterol your body needs. HDL is the good cholesterol and it’s job is to help keep your arteries clear and free of plaques LDL is the bad cholesterol and it forms plaques in your arteries causing them to harden and narrow
Carbohydrates What is carbohydrates? It is a biomolecule consisting of carbon, hydrogen and oxygen atoms. What is the importance of carbohydrates in your diet? Any food that has a high carbohydrates are important part of a healthy diet. What are the benefits of carbohydrates? They provide your body with glucose that is converted to energy used to support bodily functions and physical activity. What are the characteristics of carbohydrates? They contain elements of carbon, hydrogen and oxygen and that their combustion will yield carbon dioxide plus one or more molecules of water. What are the benefits of carbohydrate? It is one of the main nutrients in our diet.
Phosphorus, nitrogen, sulfur, and oxygen are occasionally found in lipids, which are primarily made of carbon, hydrogen, and oxygen atoms. The monomers of lipids are fatty acids and glycerol. Because lipids often contain nonpolar molecules (i.e., bonds between carbon and hydrogen atoms are not polar), they are hydrophobic and insoluble in water Types Of Lipids 1. Triglycerides (Fats- oils) 2. Phospholipids (phosphatidic acid) 3. Steroids (hydrocortisone-prednisone) 4. Waxes (beeswax) Why do we need to eat lipids? They are important in the diet as energy sources and as sources of essential fatty acids and fat soluble vitamins, which tend to associate with fats. How much lipids should we eat daily? No more than 35% Lipids functions 1.Lipids can be used as long-term energy storage. 2. Lipids are the main component of the cell membrane. 3. Lipids act as waterproof coverings. 4. Lipids act as thermal insulators. 5. Steroids, such as hormones, serve as chemical messengers
Large biomolecules and macromolecules known as proteins are made up of one or more extended chains of amino acid residues. Among the many tasks that proteins carry out in living things include catalysing metabolic processes, replicating DNA, reacting to stimuli, giving cells and organisms structure, and moving molecules from one place to another. The primary way that proteins differ from one another is in the order of their amino acids, which is determined by the nucleotide sequence of their genes and typically causes a protein to fold into a certain 3D structure that controls its activity. Your body requires protein as a food in order to function properly and to help cells grow and repair. You may get protein in a variety of foods, so it's crucial that you include a sufficient amount of protein in your diet each day. The amount of protein you require in your diet depends on your weight, gender, age, and state of health. Eating a variety of foods will help you meet your protein d...
What is water? Its the liquid that descends from the clouds as rain, forms streams, lakes, and seas, and is a major constituent of all living matter. Water Structure: A water molecule consists of two hydrogen atoms and one oxygen atom . ( H₂O ) Water Properties: - Surface Tension - Density - Polarity - Adhesion - Cohesion - Viscosity - Heat of Vaporization - Boiling Point - Specific Heat Capacity Importance of W ater: Getting enough water every day is important for your health. Drinking water can prevent dehydration, a condition that can cause unclear thinking, result in mood change, cause your body to overheat, and lead to constipation and kidney stones. Characteristics: - Water is polar - Water is an excellent solvent - Water has high heat capacity - Water has high heat of vaporization - Water has cohesive and adhesive properties - Water is less dense as solid than liquid Benefits of drinking water: - Promotes weight loss - Flushes out toxins - Improves skin co...
