The Many Types of Proteins. (1:00)
Transcript
Linus Pauling: Proteins are very important substances. I think that a human being may well have
in his body as many as a hundred thousand different kinds of proteins. For example,
fingernail is a protein, hairs is a protein, the skin is composed of proteins and
some other substances, muscle is protein, in the saliva there are proteins that help
in digesting food, in the stomach there are proteins such as a pepsin that help in
digesting food, in the tears there is a protein lysozyme that helps to protect the
eyes against infection, in the blood inside the red corpuscles there is a very important
protein, hemoglobin. There are a hundred million molecules of hemoglobin in every
red cell in the human body. These are the substances we are trying to learn more
about now in order to understand the functioning of the human body.
