	Peptide - Wikipedia, the free encyclopedia
		A polypeptide is a single linear chain of amino acids.
		A protein is one or more polypeptides more than about 50 amino acids long.
		An oligopeptide or (simply) a peptide is a polypeptide less than 30-50 amino acids long.

	Proteins
		The primary structure of a segment of a polypeptide chain or of a protein is the amino-acid sequence of the polypeptide chain(s), without regard to spatial arrangement (apart from configuration at the alpha-carbon atom).
		The alpha-helix and beta-structure conformations for polypeptide chains are generally the most thermodynamically stable of the regular secondary structures.
		However, unlike alpha-helices which are composed of residues from a continuous polypeptide segment (i.e., hydrogen bonds between CO of residue I and NH of residue I+3), beta-sheets are formed from strands that are very often from distant portions of the polypeptide sequence.

	Polypeptide Conformations 4-6
		In polypeptide chemistry the term "conformation" should be used, in conformity with current usage, to describe different spatial arrangements of atoms produced by rotation about covalent bonds; a change in conformation does not involve the breaking of chemical bonds (except hydrogen bonds) or changes in chirality (see Cahn et al.
		On the other hand in polypeptide chemistry the term "configuration" is currently used to describe spatial arrangements of atoms whose interconversion requires the formal breaking and making of covalent bonds (note: this usage takes no account of the breaking or making of hydrogen bonds).
		The secondary structure of a segment of polypeptide chain is the local spatial arrangement of its main-chain atoms without regard to the conformation of its side chains or to its relationship with other segments.
