Living organisms must be able to:Exchanges matter and energy with its surroundings.Transform matter and energy into a different form.Responding to changes in their environment.Growing.Reproduce.All of these changes are due to large organic compounds called macromolecules.Macromolecules is a combination of many similar smaller molecules polymerized into a chain structure.In
living organisms, there are three main types of macromolecules that
controls all the activities and determine what an organism will do and
be.Protein.carbohydrateNucleic acids.1.Protein are macromolecules which are polymers of amino acids.In
a review of protein chemistry is a complex organic compounds of high
molecular weight polymer with a monomer in the form of amino acids
linked by peptide bonds
For a discussion we examine the first protein monomer building blocks of protein are amino acidsAmino
acids are organic compounds having carboxylate functional group (COOH)
and amine (NH2) attached to a carbon atom (Cɲ) the same, the atom is
also generally a C asymmetric. The
detailed structure of amino acids built by a C atom that binds to four
groups namely amine (NH2), a carboxylic group (COOH), a hydrogen atom
(H), and the rest of the group R. This cluster distinguishes one amino acid with another amino acid. Carboxylate
groups of acidic amino acid causes the amine group is basa.Hal is due
to protonation, the amine group becomes - [NH3 +] and a carboxylate ion -
[COO-], so that amino acids have two charge and is called the
zwitter-ion. Classification of Acid acids
based on the nature and structure of the leaving group (R), as R groups
that are acidic, alkaline, sulfur-containing R groups or hydroxyl, R as
aromatic compounds, aliphatic and cyclic. However, the commonly used classification is the nature of the polarity of the group R.2.Karbohidrat
('hydrates of carbon', carbohydrate) or saccharides (from the Greek
σάκχαρον, sákcharon, meaning "sugar") is a majority of the most abundant
organic compound on earth. The
simplest forms of carbohydrate molecules consist of one molecule of
simple sugars called monosaccharides, such as glucose, galactose, and
fructose. Many
carbohydrates are polymers made up of sugar molecules that are strung
into long chains and can also ramify, called polysaccharides, such as
starch, chitin, and cellulose. In
addition to monosaccharides and polysaccharides, there is also a
disaccharide (two monosaccharides series) and oligosaccharides (chain
several monosaccharides).3. Nucleic acids were first isolated macromolecules of the cell nucleus. Nucleic acids form linear chains which is a combination of nucleotide monomers as the builder unit. This molecule stores information cell growth and reproduction.
Nucleotide monomers as the primary structure of nucleic acids obtained from the hydrolysis of nucleic acids. Further hydrolysis of the nucleotide monomers will produce phosphoric acid and nucleoside. Hydrolysis process was carried out under alkaline conditions. If
hydrolysis continued to nucleoside compounds in aqueous acidic solution
will produce a sugar molecule and nitrogen bases to form heterocyclic. So the composition of the constituent molecules of nucleic acid known,
Based on the above article, the classification of amino acids based on the nature and the leaving group R, The detailed structure of amino acids built by a C atom that binds to four groups namely amine (NH2), a carboxylic group (COOH), a hydrogen atom (H), and the leaving group R. Why is a hydrogen atom (H) does not determine the classification of amino acids?
BalasHapusI will try to answer your question, although not entirely correct. as we know, the amino acids have an asymmetric C atom that binds to four different groups. each group has its own function. amino carboxylic acid causes acidic, alkaline amine causing properties, while R indicates the classification based on polarity. whereas H indicates that it was originally a hydrocarbon that has undergone many modifications. I apologize if the answer is wrong. thank you
BalasHapusI tried to answer your question, the amino acid classification based on the nature and structure of the leaving group (R), as R groups that are acidic, alkaline, sulfur-containing R groups or hydroxyl, R as aromatic compounds, aliphatic and cyclic.That's why a hydrogen atom (H) does not determine the classification of amino acids?
BalasHapusI will try to answer your question sorry if my answer was not correct. Hydrogen atoms (H) does not determine the classification of amino acids because this atom has its own function in which the Hydrogen Atom is about half of the atoms in the protein. so Hidrogen atoms Contribute to the complex energy landscape of proteins
