Which two of the four macromolecules, do you believe to be the most important for life? Give evidence to support your suggestion (include a full description of the macromolecules) Describe both in terms in structure and function.

From my study of macromolecules I decided to choose proteins and carbohydrates as my main two macromolecules. To me they are the most important two. Carbohydrates are important because they are a source of immediate energy and controls structure of cells such as cell wall etc. Without this source of energy the animal body could not carry out the functions properly so this is why carbohydrates are so important. Now proteins have many uses for example enzymes and transport proteins. Proteins provide support for example keratin which gives structure to hair and nails. From the information I have gathered it will show you my point of view and my reason why I believe these are the two most important

Glucose (C6H12O6) which is the most common monosaccharide. The molecule has a carbonyl group and multiple hydroxyl group. Depending on the location of the carbonyl group, a sugar is either an aldose or a ketone. Glucose is an aldose fructose is a structural isomer of glucose is a ketone monosaccharides, particularly glucose are major nutrients for cells. The process of cellular respiration, cells extract the energy stored in the glucose molecule (Campbell & Reece, 2005). The molecule is a sugar that provides major fuel for cellular to work. But the carbon skeleton works on the row material for synthesis of all different verities of small organic molecules. For example amino acids and fatty acids. Such sugar molecules that are not immediately used are incorporated into disaccharides and polysaccharides. Glucose which is a monosaccharide has a structure of rings. To form a glucose ring, carbon 1 bonds to the oxygen which is attached to carbon
