Biomolecules chart

In Biology, in the past few classes, we’ve been studying and learning about some of the most important biomolecules: carbohydrates, proteins and lipids. Then, we had to confiscate a chart comparing these 3. I worked with Rochi Hartmann and Bauti Olaizola.

Carbohydrates Lipids Proteins
Chemical elements Carbon, hydrogen and oxygen Carbon, hydrogen and oxygen Carbon, nitrogen, hydrogen and oxygen
Bonds Glycosidic bonds Ester bonds Peptide Bond
Components Monosaccharides, disaccharides and oligosaccharides Fatty acids + glycerol Aminoacids
Solubility All solubles except from oligosaccharides that are not soluble Insoluble Some are soluble (ex: haemoglobin) and others are not (ex: keratin)
Functions Provide energy to respire, regulate blood glucose and use proteins in other beneficial ways Act as insulators, a source of energy and also are used as storage for energy Help cell growth and makes new ones. It’s a source of energy. Proteins also repair tissues and produce enzymes
Chemical Tests Benedict solution. We have to test for reducing sugars. We carry out this test by adding the benedict reagent to a food sample and then heat it up. If sugars are present then an orange/red colour will appear. Ethanol emulsion. We first chop the food sample and put it into a test tube. We then add ethanol and shake it up. If a milky emulsion appears at the top of the mixture, then lipids are present. Biuret Solution. We add some drops of the biuret reagent to our food sample and if a purple color appears then proteins are present, if not the mixture will remain the same.
Sources Bread, sugar, pasta Oil, avocado and butter Egg, meat and soya

We also had to search for a definition for HYDROLYSIS and we came up with this:

Definition: Hydrolysis is the break-down of a component because of its reaction to water.
– Hydrolysis is the opposite of condensation. In the last one, two molecules join together into a larger one and eject a water molecule. Hydrolysis adds water to break down, whereas condensation builds up by removing water.
