Within this perspective, an organism does not consist of a hierarchy of structures like a machine, but rather a dynamic hierarchy of processes, dynamically maintained and stabilized at different time scales. With this respect, two processual approaches on enzymes by Stein (Hyle Int J Philos Chem 10(4):5–22, 2004, Process Stud 34:62–80, 2005, Found Chem 8:3–29, 2006) and by Guttinger (Everything Flows: Towards a Processual Philosophy of Biology, Oxford University Press, Oxford, 2018) allows to think of macromolecules as relational and processual entities. In this work, I propose to extend their arguments to another case study within the biochemical domain, which is the case of ligand receptors and receptor-mediated biosignaling. The aim of this work is to analyze the case of G Protein-Coupled Receptors and biosignaling under the consideration of a processual ontology. I will defend that the processual ontology framework is adequate for the biochemical domain and that it allows accounting for the current biochemical knowledge related to the case study.</p></div>","PeriodicalId":568,"journal":{"name":"Foundations of Chemistry","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4922403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beyond human capacity of constructing mental models, scientists construct complex explanations about phenomena, named scientific or theoretical models. In this work we revisit three vissions: the first one concern about the polisemic term “model”. Our proposal is to discriminate between “mental models” and “explicit models”, being the former those “imaginistic” ideas constructed in scientists’—o teachers—minds, and the latter those teaching devices expressed in different languages that tend to communicate any “scientific model”. From this point of view, the class is considered a place where teachers’ mental models should be learned by novice students by decoding their teaching devices which are expressed in different languages. Other proposal of this work claims to distinguish the term “representation” with respect to its artistical or instrumental origin, highlighting that they are types of teaching devices and that artistical representations are always analogies. Finally, data about the construction of freshmen’s wrong mental models related to the use of the analogy between the chemical combustion and the global process of cellular respiration from glucose is presented to reinforce previous epistemological reflections.</p></div>","PeriodicalId":568,"journal":{"name":"Foundations of Chemistry","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4743823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although some of the literature identified it as the important ore cinnabar (red mercury(II) sulfide), some questioned that identification or even ambiguously described it as a substance produced from lead. A modern chemical study was conducted and identified the latter substance as minium (trilead tetraoxide). The reason for the medieval authors not distinguishing between those two compounds is discussed and the fact that the dictionaries of modern written Arabic commonly have the words <i>zinjafr</i> and <i>cinnabar</i> listed as equivalents is also explored.

Such triads are groups of three elements, one of which has approximately the average atomic weight of the other two elements, as well as having intermediate chemical reactivity. I also examine Jensen’s attempted reconstruction Mendeleev’s use of triads in predicting the atomic weights of three hitherto unknown elements, that were subsequently named gallium, germanium and scandium. The present article then considers the use of atomic number triads, in conjunction with the phenomenon of first member anomaly, in order to offer support for Janet’s left-step periodic table, in which helium is relocated into group 2 of the table. Such a table features triads in which the 2nd and third elements of each group, without fail, fall into periods of equal length, a feature that is absent in the conventional 18-column or the conventional 32-column table. The dual sense of the term element, which is the source of much discussion in the philosophy of chemistry, is alluded to in further support of such a relocation of helium that may at first appear to contradict chemical intuition.</p></div>","PeriodicalId":568,"journal":{"name":"Foundations of Chemistry","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10698-022-09434-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4651745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is also used figuratively like ‘social structure.’ While unobservable, what is referred to is empirically accessible. By contrast, molecules are neither observable nor empirically accessible. What philosophical grounds enable us to design invisible structure of molecules? Our cognition of objects becomes realized as phenomena when objects are given to our phenomenal fields. (Ochiai, Found Chem 22:77–86, 2020a, Found Chem 22:457–465, 2020b, A philosophical essay on molecular structure, Cambridge Scholars Publishing, Newcastle upon Tyne, pp 147–174, 2021) A phenomenal field is a pictorial representation of the mind’s self-transcending character and shows the relation between ‘self’ and ‘world.’ Molecular structure becomes realized as an affordance of molecules in a phenomenal field proper to organic chemists. It is a context-sensitive dispositional attribute of an {organic chemist-world} complex. Although designing molecules presupposes molecular structure, the latter is not sufficient for the former to make sense. Molecules must be designable as well. Designing molecules aims to create or modify molecular structure in order to provide compounds with certain chemical and/or physical properties. That is, designable molecules make sense in contexts in which they serve as a means to achieve this purpose and become realized as an affordance. Given that molecular structure and designable molecules are affordances of molecules, the fact that there are contexts in which they make sense provides grounds for conceiving and designing invisible structure of molecules. Heidegger’s arguments in <i>Being and Time</i> about characteristics of the being of beings corroborate our argument that what becomes realized as an affordance exists as what he calls a useful thing for us.</p></div>","PeriodicalId":568,"journal":{"name":"Foundations of Chemistry","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4170446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
