2007 AP Question 1 A) Three macromolecules that are very important components of the Cell Membrane of Eukaryotic organisms include molecules such as phospholipids‚ cholesterol and Glycoproteins all of which contribute to the continued functioning of the cell membrane. Phospholipids Structure: form the majority of the cell membrane‚ two layers of phospholipids combine to form the phospholipid bilayer‚ the phospholipids are made of two fatty acid tails attached to a phosphate head‚ the phosphate

Macromolecules are molecules that are large and essential for life. They consist of carbohydrates‚ nucleic acids‚ proteins‚ and lipids. Carbohydrates are molecules that are composed of monosaccharaides. Carbohydrates include cellulose‚ starches‚ and sugars. Two tests may be used to determine the presence of the carbohydrates. Those tests are the Benedict’s test and Lugol’s Iodine Test. Proteins are another category of macromolecules. The protein is a type of macromolecule that carry out many processes

Abstract: We tested five common food items to determine which macromolecules were present. We tested for the macromolecules of simple and complex carbohydrates (sugars and starch)‚ lipids‚ and proteins. The foods tested were coconut milk‚ karo syrup‚ potato chips‚ peanut butter‚ and banana baby food. We hypothesized that coconut milk would contain all four types of macromolecules‚ karo syrup would only contain simple sugars which are monosaccharides and/or disaccharides‚ potato chips would contain

Macromolecule is a very large molecule which can get collected in the kidneys. Generally‚ the molecular weight of the macromolecular vehicle is bigger than that of the prodrugs and so this kind of system can achieve the objective. Pro-drugs have the capability to select the goal in the kidney because it can release the active drug by the action of renal enzymes

BIOL 130 Lab Report Identifying Two Macromolecules - Carbohydrates and Proteins 9/26/2013 [Type the company name] INTRODUCTION As the name suggests‚ macromolecules are large molecules that make up more than 90% of the total cell mass. These biological macromolecules vary greatly in size - from several hundred to several hundred million molecular weight units - and are made up of monomer units. There are four major classes of biological macromolecules: proteins‚ carbohydrates‚ lipids‚
