Physical organic chemistry [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2010
Physical organic chemistry – the study of the interplay between structure and reactivity in organic molecules – underpins organic chemistry, and we cannot imagine organic chemistry as a subject without knowledge of mechanism and reactivity. It is sometimes thought that the golden age of ‘physical organic chemistry’ was in the 20th century, when ...

Pulmonary surfactant and COVID-19: A new synthesis

open access: yesQRB Discovery, 2022
Chapter 1: COVID-19 pathogenesis poses paradoxes difficult to explain with traditional physiology. For instance, since type II pneumocytes are considered the primary cellular target of SARS-CoV-2; as these produce pulmonary surfactant (PS), the ...
