canito leaf extracts were used for silver nanoparticles synthesis. In this study utterly revealed the best milli molar concentrations of silver nanoparticles synthesis in diverse solvents such as aqueous‚ ethanol‚ methanol‚ chloroform and petroleum ether‚ but the excellent silver synthesized solvents only chosen for further more characterization studies. The aqueous and ethanol solvents sample and chemically synthesized oxalic acid silver synthesis got excellent wavelength in ultra-visible spectroscopy

consuming fats and proteins. According to the Mayo Clinic‚ the main goal of this diet created by Robert C. Atkins in 1972‚ was to maintain a balanced amount of carbohydrates and fats and proteins for ideal health and weight loss. When the Atkins diet was first introduced‚ it was believed that consuming too many carbohydrates led to blood sugar imbalances‚ cardiovascular complications‚ and weight gain. The main idea of restricting levels of carbohydrates consumed and increasing fats and proteins has evolved

conclusion‚ the four major macromolecules are important to growth and development because they produce and store energy‚ create muscle to build a repair the body‚ create fat when it gets cold‚ and to tell when to release amino acid to build certain protein. Macromolecules are very important and will be needed throughout life. Lipids are a macromolecule that has two functions: to protect and warm the body and to store energy. Lipids protect the body by keeping a layer of fat

continue for 3‚000 to 5‚000 glucose units. Starch is a polysaccharide comprising glucose monomers joined in α 1‚4 linkages. Glucose compounds are joined together in a chain of molecules by a process of dehydration synthesis. Dehydration refers to the removal of that water molecule. Synthesis refers to the building or "putting together" process. Through this process‚ hydrogen (H) and hydroxide (OH) ends are removed and joined separately to make water. Multiple bonds of hundreds of glucose can form complex
