Mar 8, 2022 · A chemical formula is notation that shows the number and type of atoms in a molecule. In other words, it is a written representation of a three-dimensional object. There are a few different ways of writing a chemical formula. In general, a formula includes element symbols that identify the types of atoms in the molecule.
Apr 17, 2019 · A chemical formula describes a substance, down to the exact atoms which make it up. There are three basic types of chemical formula, the empirical formula, the molecular formula, and the structural formula.
- Essential and non-essential. Nutritionists divide amino acids into two groups – essential amino acids and non-essential amino acids. Essential amino acids must be included in our diet because our cells can’t synthesize them.
- Acidic Amino Acids (Carboxylic acid side chains) Amino acids in this group include: Aspartic acid (Asp/D) Glutamic acid (Glu/E) Figure 2.4 – Carboxyl amino acids.
- Basic amino acids (Nitrogen-containing side chains) Included in this group of amino acids are: Arginine (Arg/R) Histidine (His/H) Lysine (Lys/K) Figure 2.5 – Amine amino acids.
- Aromatic amino acids. Figure 2.6 – Aromatic amino acids. Amino acids with aromatic side chains include: Phenylalanine (Phe/ F) Tryptophan (Trp/W) Tyrosine (Tyr/Y)
Oct 27, 2020 · By: Sarah Knapp. Reviewed by: BD Editors. Last Updated: October 27, 2020. Definition. Amino acids are the building blocks of polypeptides and proteins and play important roles in metabolic pathway, gene expression, and cell signal transduction regulation.
There are 20 types of amino acids commonly found in proteins. Image credit: OpenStax Biology. Amino acids share a basic structure, which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group ( NH 2 ), a carboxyl group ( COOH ), and a hydrogen atom.

Mar 21, 2024 · Electronegativity. Electronegativity is a measure of the affinity a nucleus has for outer shell electrons (Table 1.2). High electronegativity corresponds to high affinity. Electrons in a covalent bond are held closer to the nucleus with a greater electronegativity compared to a nucleus with lower electronegativity.
The pH of a solution is a measure of the concentration of hydrogen ions in a solution (or the number of hydronium ions). The number of hydrogen ions is a direct measure of how acidic or how basic a solution is. The pH scale is logarithmic and ranges from 0 to 14 ( Figure 2 ). We define pH=7.0 as neutral.
