General Concepts of Plant Biochemistry

  title={General Concepts of Plant Biochemistry},
  author={Monica Butnariu},
Biochemistry is the study of the chemical processes in living organisms. It deals with the structure and the function of cellular components such as: proteins, carbohydrates, lipids, nucleic acids and other biomolecules. Although there is a vast number of different biomolecules, many of them are complex and large molecules (called polymers), composed of similar repeating subunits (called monomers). Each class of polymeric biomolecules has a different set of subunit types. For example, a protein… 
General Concepts of Plant Biochemistry
Since all known life forms that are still alive today are descended from the same common ancestor, generally they have similar biochemistries, and it is unknown whether alternative biochemistryistries are possible or practical.

Plant embryogenesis
Ophthalmic acid is a marker of oxidative stress in plants as in animals.
OPH occurs in plants and its levels are tightly associated with oxidative stress, and its dipeptide precursor, γ-glutamyl-2-aminobutyric acid, were found to occur in phylogenetically distant plants.
Trans-oligomerization of duplicated aminoacyl-tRNA synthetases maintains genetic code fidelity under stress
Evidence is found that in organisms with duplicated genes, cells can orchestrate the assemblage of aaRSs oligomers that meet the necessities of the cell in each situation, and it is proposed that controlled oligomerization of duplicated aa RSs is an adaptive mechanism that can potentially be expanded to the plethora of organisms with duplication.
Analytical and Fluorimetric Methods for the Characterization of the Transmembrane Transport of Specialized Metabolites in Plants.
A set of procedures to isolate tonoplast membranes, to check their purity and functionality, and to characterize their transport properties are described.
Perspectives for a better understanding of the metabolic integration of photorespiration within a complex plant primary metabolism network.
Future priorities are discussed to better understand (i) the metabolic integration of the photorespiratory cycle within the complex network of plant primary metabolism and (ii) the importance of photorespiration in response to abiotic and biotic stresses.
Synthetic photosynthetic consortia define interactions leading to robustness and photoproduction
The modular nature of these communities and their unusual robustness exhibits promise as a platform for highly-versatile photoproduction strategies that capitalize on multi-species interactions and could be utilized as a tool for the study of nascent symbioses.
Effects of Different Metals on Photosynthesis: Cadmium and Zinc Affect Chlorophyll Fluorescence in Durum Wheat
Despite the similar inhibitions of the CO2 assimilation rates, the wheat photochemistry showed much more sensitivity to Cd than to Zn exposure, which indicated that both metals disturbed photosynthetic electron transport processes which led to a 4- to 5-fold suppression of the efficiency of energy transformation in Photosystem II.
Teaching and learning of medical biochemistry according to clinical realities: A case study
This case study was based on a biochemistry/nutrition question in a popular board review book about whether a homeless alcoholic man is at risk of developing a deficiency of vitamin E, which provided an opportunity to adapt the philosophy and certain basic EBM principles to find evidence for the clinical applicability of a commonly taught biochemistry topic.
Guided inquiry activities for learning about the macro‐ and micronutrients in introductory nutrition courses
A set of guided inquiry activities about macronut nutrients and micronutrients for use in introductory nutrition courses for nonscience majors found that students showed gains in both concept mastery and confidence and as students' confidence increased, post‐test concept scores also increased.
