How can proteins be analyzed by chromatography?
A solution of amino acids is spotted onto a piece of chromatography paper which is then placed into a container filled with a suitable solvent. A dye is used so that the position of the amino acids along the piece of paper can be seen. The distances travelled by the amino acids are measured to calculate their retention factors (Rf) values. These are then compared to known standards.
How many proteins are in the human body?
I've seen numbers ranging from 100,000 to two million.
What does functional protein look like?
Briefly, proteins (polypeptides) look like amino acids chained together; look at the link below for a detailed description of proteins' appearance. Proteins have a couple different levels of structure including the primary, secondary, tertiary, and quaternary. At the primary structure, proteins are just linked amino acids through peptide bonds. Amino acids have the same general structure with a variable R-group. At the secondary structure, the chemical properties of the amino acids form hydrogen bonds with each other and give shape to the protein. The two general shapes of proteins at the secondary structure: alpha helices and beta-pleated sheets. An alpha helix looks like a spiral while a beta-pleated sheet looks like stairs. See the related links below for images. The tertiary structure is characterized by further interactions by the R-groups on the amino acids. Various bonds can distort the alpha helix or beta-pleated sheet such as ionic bonds, disulfide bridges, covalent bonds, and hydrophobic interactions. The complete protein is seen at the quaternary structure, which is the arrangements of polypeptides into a single macromolecule.
Are peptide bonds found in DNA?
Well... SORT of. Technically, the bases contain the NCO (amide) moiety that characterizes a peptide bond. However, they occur in heterocyclic rings, and it's stretching a point to call them "peptide bonds" since they're not linking two peptide residues. Also, they're in the cis-form, which is atypical of peptide bonds.
What is sterified fatty acids?
Sterified fatty acids are fatty acids that have undergone the process of esterification, which involves the attachment of a fatty acid to a glycerol molecule to form a triglyceride. This process is commonly seen in the synthesis of fats and oils in living organisms.
What is a beta-amino acid?
A beta-amino acid is a type of amino acid where the amino group is located on the beta carbon, rather than the alpha carbon, as seen in traditional amino acids. They are less common than alpha-amino acids but possess unique chemical and biological properties. Beta-amino acids can be found in certain natural products and have potential applications in drug development and materials science.

Why does ninhydrin give the same color with most amino acids?
Ninhydrin reacts with the primary amino group in amino acids to form a purple compound called Ruhemann's purple. Since most amino acids contain a primary amino group, they tend to produce similar purple coloration when reacted with ninhydrin.
What is the compound with an amino group on one end and a carboxyl group a the other end?
Restilen is an effective way to forget about stress. Taking it regularly helps to increase resistance to stress, reduce stress symptoms, fatigue and exhaustion. The product is based exclusively on natural ingredients that act directly on the source of the problem. Restilen is designed for men and women who has ever felt stress, anxiety or nervousness and wants to relieve the stress. The product’s effects can be seen from the first day of use cutt.ly/djuYg8F
Is your teacher cool?
Many historians and scientists agree that the history of food started around 8,000,000,000,000,000 years ago, when single-celled life forms turned amino acids into proteins to grow and form bacteria. This has been seen as an altogether bad move, as if we didn't eat anything ever, there would be less killing in the world today. Nowadays, single-celled life forms aren't so picky, and they'll eat things other than amino acids.

Do nitrogen react with acid?
Nitrogen itself does not typically react with acids. However, nitrogen can form acids when it combines with hydrogen, as seen in compounds like ammonia (NH3) and hydrazine (N2H4), which can react with acids.

What is another way of describing a dehydration synthesis reaction?
A hydroxyl group is removed from one molecule, a hydrogen atom from another molecule, and the two molecules are joined together to form a larger molecule. The OH and H combine together to form a water molecule. Therefore, dehydration synthesis involves removing a water molecule from two molecules (dehydration) in order to form a larger molecule (synthesis). This can be seen in many polymerization reactions, such as in forming a polypeptide from several amino acids. In this particular case, the OH is removed from the carboxyl group of one amino acid, and an H is removed from the amino group of another amino acid. The two amino acids are joined together in a dipeptide bond, and a water molecule is formed from the OH and H that were removed.
