There are four biological marcomolecules essential to the function of a cell: lipids‚ proteins‚ carbohydrates and nucleic acids. Proteins are made up of amino acids that have a carbon in the center of the structure with four chemical groups attached to the sides. Traditionally protein is understood to assist in the development of muscle in athletic people‚ but it actually functions as structural support‚ cell adhesion‚ transport for molecules‚ and cellular communication. Through dehydration synthesis

Introduction The objective of this experiment is to identify if the 12 provided solutions contain starch‚ glycogen‚ reducing sugars or proteins. The four major biological macromolecules are carbohydrates‚ lipids‚ proteins and nucleic acids. Abundant elements in the world such as carbon and nitrogen bond in different ways to form many different molecules. The functional groups are what determine their characteristics. During the experiment‚ there will be 3 test. The iodine test is completed to

The primary objective of this experiment is to determine the stress that various alcohols have on biological membranes. Membranes within cells are composed mainly of lipids and proteins and often serve to help maintain order within a cell by containing cellular materials. Different membranes have a variety of specific functions. One type of membrane-bound vacuole found in plant cells‚ the tonoplast‚ is quite large and usually contains water. In beet plants‚ this membrane-bound vacuole also contains

Is health a biological or social issue? Changes in society‚ of how people live‚ have ultimately led to a ‘medical model’ of health. Trends of human evolution have led to urbanisation and industrialisation. Beginning over 12000 years ago (Halliday & Davey 2010) when ancestral humans began settlements and left their nomadic lifestyles behind reaching a climax sometime during 2006-2007 when for the first time in human history more people were living in cities and urban environments than in the
