If you take a long strand in your palm, stretch it out to the tip of your index finger, loop it to your middle finger, then back to your palm, then out to your ring finger, back to your palm and out to your little finger, you form a type of beta sheet
We believe that the beta helix is a primitive or simple beta sheet
," says MIT biologist Jonathan King.
The chain folds back and forth on itself to create a structure, called a beta sheet
, that resembles accordion pleats.
Whereas a single alpha-helix consists of an elegant spiral of 15 to 20 amino acids, the beta sheet
requires 60 to 70 amino acids.
Weak links connect these strands into a pleated structure called a beta sheet
(SN: 5/15/93, p.
As he did this, he began to realize that rather than forming an alpha helix, peptides with this amino acid sequence can arrange into a different protein structure known as a beta sheet
The molecule has two different features: a series of slats called a beta sheet
(a structure commonly found in proteins) and regions of complicated loops.
consist of beta strands (also [beta]-strand) connected laterally by at least two or three backbone hydrogen bonds, forming a generally twisted, pleated sheet.
In figure-4, positions of alpha helices and beta sheets
have been mentioned.
Through a process that remains mysterious, these bundles of beta sheets
then turn dangerous.
