These methods were based on the helix- or sheet-forming propensities of individual amino acids, sometimes coupled with rules for estimating the free energy of forming secondary structure elements. The first widely used techniques to predict protein secondary structure from the amino acid sequence were the Chou–Fasman method [ 17 ] [ 18 ] [ 19 ...
The beta sheet (β-sheet, also β-pleated sheet) is a common motif of the regular protein secondary structure. Beta sheets consist of beta strands ( β-strands ) connected laterally by at least two or three backbone hydrogen bonds , forming a generally twisted, pleated sheet.
In biochemistry, a Ramachandran plot (also known as a Rama plot, a Ramachandran diagram or a [φ,ψ] plot), originally developed in 1963 by G. N. Ramachandran, C. Ramakrishnan, and V. Sasisekharan, [1] is a way to visualize energetically allowed regions for backbone dihedral angles ( also called as torsional angles , phi and psi angles ) ψ ...
Story structure or narrative structure is the recognizable or comprehensible way in which a narrative's different elements are unified, including in a particularly chosen order and sometimes specifically referring to the ordering of the plot: the narrative series of events, though this can vary based on culture.
This is a list of human anatomy mnemonics, categorized and alphabetized.For mnemonics in other medical specialties, see this list of medical mnemonics.Mnemonics serve as a systematic method for remembrance of functionally or systemically related items within regions of larger fields of study, such as those found in the study of specific areas of human anatomy, such as the bones in the hand ...
A plot summary is a retelling, a summary, or an abridged or shortened précis of the events that occur within a work of fiction. The purpose of a plot summary is to help the reader understand the important events within a work of fiction, be they of the work as a whole or of an individual character.
The cell is the basic structural and functional unit of all forms of life.Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function.
The series was re-released in 2003 on DVD as Acland's DVD Atlas of Human Anatomy. The series uses unembalmed human specimens to illustrate anatomical structures. [3] Intended for use by medical, dental and medical science students, the video teaching aid uses simple language and high quality images.
