Molecular Structure and Acidity02:34

Molecular Structure and Acidity

20.8K
An acid can be deprotonated to form a conjugate base or an anion. If the produced anion is more stable, then the acid is stronger. On the contrary, if the anion is unstable, then the acid is weaker. Hence, to determine the acidity of the compound, the stability of its conjugate base is studied using various factors.
The size effect explains the change in atomic size on acidity. When comparing the acids formed from elements that belong to the same column in the periodic table, their atomic sizes...

Fruit Development, Structure, and Function

25.2K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Seed Structure and Early Development of the Sporophyte

31.0K
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

Acid Strength and Molecular Structure

Binary Acids and Bases
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.9K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

  • Molecular oncology

Background:

  • Mitochondria are vital organelles involved in energy production, signaling, and cell death.
  • Mitochondrial dynamics, regulated by fusion and fission, are crucial for cellular homeostasis and stress adaptation.
  • OPA1 (opticin1) is a key GTPase regulating inner mitochondrial membrane fusion, cristae structure, and apoptosis.

Purpose of the Study:

  • To review OPA1 dysregulation in cancer.
  • To highlight OPA1 as a potential therapeutic target in oncology.
  • To explore computational approaches for identifying OPA1 modulators.

Main Methods:

  • Literature review of OPA1's role in cancer.
  • In silico analysis of OPA1's GTPase domain and Interface 7.
  • Conceptual framework for computational drug discovery.

Main Results:

  • OPA1 dysregulation is linked to cancer initiation, progression, and therapeutic resistance.
  • Preliminary in silico data suggest OPA1's GTPase domain and Interface 7 are promising therapeutic targets.
