Determining the Amino Acid Composition of a Protein

Determining the Amino Acid Composition of a Protein

In this web cast and the three that follow we’re going to take a look at the chemical analysis and synthesis of polypeptide chains. Today, we take for granted the idea that a naturally occurring polypeptide like insulin has a unique chemical composition and a specific arrangement of amino acids along the chain. That’s its […]

Protein Transport into Mitochondria

Protein Transport into Mitochondria

Hello frnds in this videos we will be discussing abt Protein Transport into Mitochondria……….. we know Most of the proteins destined for mitochondria are synthesised in the cytosol and then these proteins are transported into the mitochondria … and for this transport to occur the Proteins contain Signal Sequences , where to get transported in […]

Is Our Food Becoming Less Nutritious?

Is Our Food Becoming Less Nutritious?

Is our food becoming less nutritious? Many people claim that the nutrient content in our food has been decreasing over the decades. But is this really true, and should we be worried? A study published in 2004 looked at 43 different common garden crops, and how their nutritional value had changed between 1950 and 1999. […]

Proteins and Nucleic Acids

Hey folks, this is going to be our second screencast on the big four molecules, and this time we’re going to talk about proteins and nucleic acids. So when we talked about carbohydrates and lipids, we mostly used carbon hydrogen oxygen and nitrogen, but today we’re going to add phosphorus and sulfur into the mix […]

Biomolecules: The Proteins

Biomolecules: The Proteins

Welcome to Biomolecules: The Proteins. Proteins do most of the work in cells including DNA replication, transportation of molecules, and providing structure to cells. They’re also some of the largest biomolecules because they’re made up of long chains of building blocks, called amino acids. Proteins comprise ten to thirty percent of cell mass, and have […]
