Beta skeleton

In computational geometry and geometric graph theory, a β-skeleton or beta skeleton is an undirected graph defined from a set of points in the Euclidean plane. Two points p and q are connected by an edge whenever all the angles prq are sharper than a threshold determined from the numerical parameter β. (Wikipedia).

Bones: Structure and Types

We've got the skin covered, so now let's take a look at bones! These give structure to the body. Bone is a type of tissue, but an actual complete bone is an organ, because there is lots of stuff inside besides bone. What else is in there? Find out here! Watch the whole Anatomy & Physiolog

Protein Structure - Primary, Secondary, Tertiary, & Quarternary - Biology

This biology video tutorial provides a basic introduction into the four levels of protein structure - primary, secondary, tertiary and quarternary structure. The primary structure of a protein is based on the sequence of amino acids. The secondary structure is based on localized shapes s

A Level Biology Revision "Protein Structure 1"

In this video we start looking at the first two levels of protein structure. These are called the primary structure and the secondary structure. We start by looking at how the primary structure and how this is critical for the function of a protein. We then explore what is meant by seconda

Protein Structure

Everyone has heard of proteins. What are they on the molecular level? They're polymers of amino acids, of course. They make up most of your body, so we have to understand their structure very well! Check this out to learn the hierarchy of protein structure so that we can later learn all ab
