Explain the relationship between polypeptides and proteins .
Hatshy [7]

Peptide bonds, and proteins. Amino acids are the monomer building blocks of proteins. When two are joined together in a peptide bond, they form proteins.A polypeptide is amino acids that bond to each other one at a time to form a long chain held together by peptidebonds

.Polypeptides and proteins are natural and essential organic compounds of a cell. They are both composed of amino-acids. Amino-acids are naturally occurring compounds which link together to form peptides, polypeptides, and proteins. Each amino-acid contains one amine (-NH2) and one hydroxyl (-COOH) group, as well as a specific side chain (R group). The side chain group varies in size, shape, charge, and reactivity, and is therefore unique to each amino-acid. There are 20 types of monomeric amino-acids capable of linking together in different combinations, thus conferring polypeptides and proteins with a high diversity.

A polypeptide is a polymer with a defined sequence of amino-acids linked together through covalent peptide bonds. A peptide bond is the result of a condensation reaction between two amino-acids: the carboxyl group of one amino-acid reacts with the amino group of an adjacent amino-acid, releasing a molecule of water (H2O).  

Proteins are structurally and functionally complex molecules. The term protein is used to describe the three-dimensional structure formed by the folding of one or more polypeptides. Proteins present four levels of structural organization, with the polypeptide being the primary structure. A protein has a secondary structure when polypeptide chains form α helices and β sheets.

Ludmilka [50]
Photosynthesis is when plants turn light from the sun into food (energy). The light from the sun is turned into energy by using chlorophyll. Chlorophyll absorbs blue and red light to turn Co2 and H2o into glucose.
