carbohydrate molecules that are used for cell recognition and cholesterol to provide membrane stability. Phospholipid molecules are the most abundant component found in the plasma membrane. Phospholipids molecules are composed of a phosphate head and a lipid tail; the structure of a cell membrane is a double layer of these phospholipid molecules. The heads face out into the water solutions both inside and outside of the cell. Proteins found within the membrane can be attached to either the inside

What conditions are necessary for digestion of lipids‚ carbohydrates‚ protein? Certain conditions are required for digestion. I will find that enzyme is required for digestion of lipids‚ carbohydrates‚ protein. There are many conditions that are necessary for digestion of lipids‚ carbohydrates‚ protein such as pH and enzyme and substrate. The test tube that digestion of lipids occurs in was test tube 1‚3‚4‚ test tube 2 there was no digestion because there was no enzyme. Test tube 1 was the fastest

What am I Eating Anyway? Question: Are the Biomolecules Sugar‚ Starch‚ Protein‚ and Lipids present in the foods Turkey Gravy‚ Peas‚ and Applesauce? Background Information: Learning experience 4 teaches the understanding of how to identify a small sample of Biomolecules within a wide variety of substances. The specific biomolecules that were observed in the lab were Sugar‚ Starch‚ Protein‚ and Lipids. These 4 Biomolecules were tested within the foods applesauce‚ peas‚ and turkey gravy. These

into four main categories which each have there own structure. These structures are the key to the macromolecules functions as each of them do a specific task in the body. Macromolecules are grouped into carbohydrates‚ nucleic acids‚ proteins‚ and lipids. In most cases macromolecules are polymers‚ which is a long molecule which are made by linking together a large number of small‚ similar compounds called monomers. Polymers are formed by a dehydration reaction‚ this happens by the -OH group being

Macromolecules The four macromolecules that are essential to life are Carbohydrates‚ Lipids‚ Proteins‚ and Nucleic Acids. Carbohydrates Carbohydrates are made up of carbon‚ hydrogen‚ and oxygen. It provides energy for the body‚ especially the brain and the nervous system. The food sources are in sugar and grains. Lipids Lipids are made up of hydrogen‚ carbon and oxygen. It provides Energy storage‚ acting as structural components of cell membranes‚ and hormone production

BIOLOGY LAB REPORT PRACTICAL M1 TESTING FOR MACROMOLECULES Title : Testing for Macromolecules Abstract : To test for macromolecules (carbohydrates‚ lipids‚ nucleic acids‚ and proteins)‚ iodine solution‚ alcohol‚ aceto-orcein stain and copper sulfate solution are used. The conclusions for all of the tests are positive. Introduction: A) Carbohydrate (starch) Carbohydrates are chemical compounds that contain oxygen‚ hydrogen‚ and carbon atoms. They consist of monosaccharide
