Calculation in kindNOTOC Calculation in kind or calculation in-natura is a way of valuating resources and a system of accounting that uses disaggregated physical magnitudes as opposed to a common unit of calculation. As the basis for a socialist economy, it was proposed to replace money and financial calculation. In an in-kind economy products are produced for their use values (their utility) and accounted in physical terms. By contrast, in money-based economies, commodities are produced for their exchange value and accounted in monetary terms.
Socialist calculation debateThe socialist calculation debate, sometimes known as the economic calculation debate, was a discourse on the subject of how a socialist economy would perform economic calculation given the absence of the law of value, money, financial prices for capital goods and private ownership of the means of production. More specifically, the debate was centered on the application of economic planning for the allocation of the means of production as a substitute for capital markets and whether or not such an arrangement would be superior to capitalism in terms of efficiency and productivity.
Acide aminé protéinogènevignette|Structure de la , parfois considérée comme un aminé protéinogène bien qu'elle ait une chaîne latérale identique à celle de la méthionine. Elle amorce la biosynthèse des protéines chez les procaryotes et dans les mitochondries et les chloroplastes des eucaryotes, mais pas dans le cytosol de ces derniers. Elle dérive de la méthionine par adjonction d'un groupe aldéhyde sur l'atome d'azote de l'amine primaire Un acide aminé protéinogène est un acide aminé incorporé dans les protéines lors de la traduction de l'ARN messager par les ribosomes.
