This contains important things you must know about amino acids for biochemistry. This material is essential for understanding proteins and amino acids. I also added some nutritional aspects of each amino acid. Word count (15273).Included free is an 875 Word vocabulary list.
The following is a small part of what you will find.
The Beta pleated sheet differs markedly from the rod like alpha helix. A polypeptide chain in a beta pleated sheet, called a beta strand is almost fully extended rather than being tightly coiled as in the alpha helix. The axial distance between adjacent amino acids is 3.5A, in contrast with 1.5A for the alpha helix. Another difference is that the beta pleated sheet is stabilized by H bonds between NH and CO groups in different polypeptide strands, whereas in the alpha helix the H bonds are between NH and CO groups in the same strand.
