This Unit studies 'proteins'. Starting with a simple analysis of the molecular make up, the Unit moves on to look at the importance of protein and how they are digested and absorbed
After studying this course, you should be able to:
- understand that the human body, and everything else, is made up of atoms and that there are about 26 different sorts of atom in the human body, combined into numerous different sorts of molecules
- understand that amino acids contain carbon, nitrogen, oxygen and hydrogen atoms, some contain an atom of sulphur and that there are about 20 different amino acids, with different side-chains (R groups)
- understand that amino acids are linked via peptide bonds to make polypeptides and proteins
- understand that each protein molecule can be hundreds of amino acids long and the amino acids must be joined in a precise order, which is specified by a code in the DNA in the chromosomes
- understand that the side-chains (R groups) of the amino acids can interact with one another to fold the protein into a particular shape which is essential for the protein to function correctly.
