T. e. " molecular structure of nucleic acids: a structure for deoxyribose nucleic acid " was the first article published to describe the discovery of the double helix structure of dna, using x ray diffraction and the mathematics of a helix transform. it was published by francis crick and james d. watson in the scientific journal nature on pages.

Paper Molecular Model Of The Alpha Helix September 1954 Pu In 1954 he became a nobel laureate in chemistry for his ground breaking work on chemical bonds and the structure of molecules and crystals. in early 1953 he had published a paper where he proposed a triple helical structure for dna. watson and crick had also previously worked out a three helical model, in 1951. but their theory was wrong. A molecule's constitution, i.e. which atoms are part of the molecule and how these atoms bond together, is usually represented by the building blocks of molecular model kits: atom models. in ball. A helix is a curve on a cylinder surface such that the angle between the curve and a plane perpendicular to the axis is constant — the distance from the axis for a point moving along the helix. Abstract. pnas papers by linus pauling, robert corey, and herman branson in the spring of 1951 proposed the alpha helix and the beta sheet, now known to form the backbones of tens of thousands of proteins. they deduced these fundamental building blocks from properties of small molecules, known both from crystal structures and from pauling's.

Abstract. pauling first described the alpha helix nearly 50 years ago, yet new features of its structure continue to be discovered, using peptide model systems, site directed mutagenesis, advances in theory, the expansion of the protein data bank and new experimental techniques. helical peptides in solution form a vast number of structures. Linus carl pauling was born in portland, oregon, on february 28, 1901, and died at his ranch at big sur, california, on august 19, 1994. in 1922 he married ava helen miller (died 1981), who bore him four children: linus carl, peter jeffress, linda helen (kamb), and edward crellin. pauling is widely considered the greatest chemist of this century.
