Proteins Structure Function In Your Diet Enzymes and Proteins in the Cell

- Proteins are made of monomers called Amino Acids. - Amino Acids are simple hydrocarbons that have functional groups on either end: a Carboxyl group and an Amino group. - When the Carboxyl of one joins with the Amino of another through condensation, it is called a peptide bond. Polypeptides (many peptides) are called proteins. PROTEIN SYNTHESIS: ~ DNA passes genetic information to RNA. ~ The RNA finds a Ribosome in the cells and they bond. ~ The Ribosome finds the Endoplasmic Reticulum of the cell and builds the protein with bases in the cell cytoplasm based on the information provided by the RNA. ~ The Endoplasmic Reticulum twists the protein into the shape that it must be in order to do its job. Shape determines the function of most proteins. Structure of Proteins

Functional Groups in Proteins Proteins are made up of amino acids. And the only way to determine if a molecule is an amino acid is by its functional group. This is because the only similarity between all amino acids is that they have the same functional group. The way that these amino acids combine into a protein is also dependent on functional groups. As seen above, the amino acids only bond because the functional group on the end bonds to similar functional groups.

Proteins Proteins are a necessary part of the developmental process that each person goes through in life. Proteins help to develop muscles that are used to help a person to move and function. Proteins are found in meats, eggs, dairy products, of course fruits and vegetables and other foods. Proteins, in conjunction with a healthy diet and exercise, can help a person become strong and healthy.

-Antibodies of the human immune system are proteins -Proteins carry many vital substances throughout the body, for example, the protein Hemoglobin in red blood cells carries Oxygen. -They also transmit or express all hereditary characteristics that are controlled by genes.
