• are a major source of energy for living organisms. The process of photosynthesis uses carbon dioxide (CO2) and water (H20) to produced sugar-glucose and oxygen using sunlight as energy. They can be micro molecule-monosaccharide and macromolecule- disaccharide and polysaccharide.

  Carbohydrates
• are the simplest carbohydrates and the only sugar that can be utilized and absorbed by the body. The common examples of monosaccharides are glucose, galactose, and fructose.

  Monosaccharides
• is the most abundant monosaccharide. It is found in the bloodstream and provides immediate energy for the body.

  Glucose
• is a monosaccharide found in milk but unlike glucose, they are not found freely in nature because the body needs to break down

  Galactose
• is found in fruits and is considered the sweetest monosaccharide.

  Fructose
• consist of two monosaccharides bonded together by a covalent bond called glycosidic linkage. Sucrose, Lactose, and Maltose are examples

  Disaccharides
• Sucrose is a disaccharide composed of one glucose and one fructose molecule. Sugar cane is one of the sources of sucrose.


  Sucrose
• is also referred to as milk sugar.It is composed of one glucose and one galactic sugar


  Lactose
• is composed of two glucose sugars. It is used in making beer


  Maltose
• consist of ten or more units of monosaccharides. Glycogen, starch, and cellulose are __________

  polysaccharides
• Is a stored sugar in animals, human liver, and muscles.

  Glycogen
• is a stored sugar in plants.. It has a structure of B-glucose (beta glucose) polymer.

  Starch
• is a polysaccharide that is also found in plants unlike starch its function is for the structure in plants' cell walls. It cannot be digested by humans. It has a structure of ß-glucose (beta glucose) polymer.

  Cellulose
• function as a source of energy, for protection and insulation and it is also a major component of the cell membrane. They are hydrophobic, meaning they are insoluble in water but with nonpolar solvents. Lipids can be dissolved such as acetone. Lipids are classified from simple: steroids to complex: triglycerides, phospholipids, and waxes.

  lipids
• One of the examples of this is the cholesterol (C27H460). It is the bases of other steroid such as the male and female hormones, and vitamin D. it is stored and released by the liver to meet the energy needed by the body.


  Simple Lipids: Steroids
• are found in plants and animals together with the cholesterol it is mostly found in the blood. They can be in solid or liquid form.Solid triglycerides are called fats while liquid triglycerides are oils.


  Complex Lipids: Triglycerides
• are the major components of the cell membrane. It has two parts the phosphate head and hydrophobic tail. It is responsible for controlling the material that passes through inside and outside of the cell.

  Phospholipids
• are solid lipids with a low-melting point. They usually act as protective shields on plants and animals. An example of this is the beeswax.The excesscarbohydrates will be stored in the body's cells as triglyceride and will be ready whenever there is a need for energy.
