name some of his famous works
In the field of biological molecules he demonstrated that the hemoglobin molecule changes structure when it gains or loses an oxygen atom.
Linus Pauling
His early work in this area included studies of the structure of hemoglobin with his student Charles D. Coryell. He demonstrated that the hemoglobin molecule changes structure when it gains or loses an oxygen atom. 
who popularized the idea of evolution in the mid 1800s Charles Darwin and Alfred Russel Wallace. which ancient civilizations helped to shape this thought process? The ancient Greeks, Romans, Chinese, and in medieval Islamic science. what was proposed for this thought process from the first civilization mentioned above? They proposed that one type of animal, even humans, could descend from other types of animals. what was proposed for this thought process from the second civilization mentioned? They described the development of the cosmos, the Earth, living things, and human society through purely naturalistic mechanisms, without any reference to supernatural involvement. and what was proposed by the third civilization about this subject? According to Joseph Needham, Taoism explicitly denies the fixity of biological species and Taoist philosophers speculated that species had developed differing attributes in response to differing environments. what evolutionary ideas were contributed in the field of paleontology? One instance being that of James Hutton describing gradual geological processes operating continuously over deep time. can you name some famous intellects who contributed to the field of molecular biology in the 1940s -1960? Yes, Linus Pauling and Emile Zuckerkandl. can you tell me something about the first person mentioned above? He was an  American chemist, biochemist, chemical engineer, peace activist, author, and educator. what subjects did he study during his university days? He registered for two courses in chemistry, two in mathematics, mechanical drawing, introduction to mining and use of explosives, modern English prose, gymnastics and military drill.

Linus Pauling [SEP] Biological molecules
Pauling had formulated a model for the structure of hemoglobin in which atoms were arranged in a helical pattern, and applied this idea to proteins in general. In 1951, based on the structures of amino acids and peptides and the planar nature of the peptide bond, Pauling, Robert Corey and Herman Branson correctly proposed the alpha helix and beta sheet as the primary structural motifs in protein secondary structure. This work exemplified Pauling's ability to think unconventionally; central to the structure was the unorthodox assumption that one turn of the helix may well contain a non-integer number of amino acid residues; for the alpha helix it is 3.7 amino acid residues per turn.
