Nature of the side chain
Amino acids are made up of an amino group (NH2), a carboxyl group (COOH), and a side chain (R group) that varies for each amino acid. The side chain is what differentiates one amino acid from another and gives each its unique properties.
Each codon in the genetic code codes for a specific amino acid. For example, the codon "AUG" codes for the amino acid methionine.
Amino acids are distinguished from each other by their unique side chains, which are different chemical groups attached to a central carbon atom. These side chains determine the specific properties and functions of each amino acid.
Three water molecules are formed when four amino acids join together through a process called condensation or dehydration synthesis. Each amino acid has a carboxyl group (-COOH) and an amino group (-NH2), and when they combine, a water molecule is removed for each bond formed between the amino group of one amino acid and the carboxyl group of another.
Because the number of amino acids and their exact sequence in the polypeptide chain is different for each protein; this is called the primary structure, and it determines the secondary structure of the protein - the unique three-dimensional shape that the protein can fold into.
Proteins differ from each other in their amino acid sequence, which is determined by the genetic code. This unique sequence gives each protein its specific structure and function. Differences in amino acid sequence can result in proteins with varying functions, sizes, shapes, and interactions.
Each amino acid differs from others in the side chain, also known as the R-group, which gives each amino acid its unique properties and characteristics. The side chain contributes to the amino acid's ability to interact with other molecules and determines its role in protein structure and function.
They are the building blocks that will form proteins. Each base codes for one amino acid. Adding one amino acid to another and another will make a protein.
The "R" group
amino acid
Amino acids are attached to each other via covalent bonds between the organic acid and amine groups. This covalent bond is often called a Peptide Bond.
Amino acids are made up of an amino group (NH2), a carboxyl group (COOH), and a side chain (R group) that varies for each amino acid. The side chain is what differentiates one amino acid from another and gives each its unique properties.
The attachment of two amino acids to each other takes place at the ribosome during protein synthesis. Here, the ribosome catalyzes the formation of a peptide bond between the carboxyl group of one amino acid and the amino group of another amino acid.
Each codon in the genetic code codes for a specific amino acid. For example, the codon "AUG" codes for the amino acid methionine.
Proteins differ each other in their amino acid composition and the number of amino acids that form it. Not all the proteins are the same, although they are all made up of amino acids. the sequence of amino acids is determined by the mRNA which is transcribed by DNA in the nucleus.
Amino acids differ from each other based on the side chain (R-group) that is attached to the central carbon atom. This side chain can vary in size, shape, charge, and chemical properties, which ultimately determine the overall characteristics and function of the amino acid. There are 20 standard amino acids commonly found in proteins, each with its unique side chain that confers specific properties.
Each codeword on mRNA corresponds with a single amino acid. However, There can be multiple codewords corresponding with the same amino acid.
