After a polypeptide chain has been synthesized, certain amino acids in the peptide may become modified. For each modified amino

acid, identify the standard amino acid from which it is derived. Enter the unabbreviated name of the standard amino acid. The amino acid structure shows the fully ionized form. The side chain is C H 2, C H 2, C H (O H), C H 2, N H 3 (plus). standard amino acid: Identify the modification that yields the first amino acid depicted.

Answer:

The name of the amino acid is lysine.

The number five carbon in lysine is the carbon that is hydroxylated. The modification you ask is when adding hydroxyl group (C-OH bonds). These links are made by an enzyme called hydroxylase, vitamin C acting as a cofactor. This reaction is one of the most fundamental post-translational modifications.

Answer:

The modification that yields the first amino acid depicted is lysine

Explanation:

Lysine being an amino acid used in preparation of various medicine. It is used to prevent cold as well as sore throat, which is found to be caused by the herpes simplex labialis. It can be used orally or can be directly applied over the skin. various foods have lysine in it and they are meat, cheese, certain fishes, eggs, soybeans, spirulina and also fenugreek seed.

Which forces are intramolecular and which intermolecular?
AleksAgata [21]

Butter won't melt in a fridge because of intermolecular tensions. While the bonds inside of the fat molecules are unbroken, the attractions between the fat molecules are weaker.

What intermolecular forces are present in butter?

The intermolecular forces known as London dispersion forces are the weakest and are most prominent in hydrocarbons. Due to the fact that butter molecules are hydrocarbons, London dispersion forces do exist between them.

How do intermolecular forces affect melting?

More energy is required to stop the attraction between these molecules as the intermolecular forces become more powerful. Because of this, rising intermolecular forces are accompanied with rising melting points.

Which forces are intramolecular and which are intermolecular?

Intramolecular forces are those that hold atoms together within molecules. The forces that hold molecules together are known as intermolecular forces.

Shown here is a person shaving.  Under magnification, the shaving foam might look like the image above the shaver. What type of mixture does the foam demonstrate? Give your reasoning.

Foam is a colloid. Colloids includes gas dispersed in a liquid and it also includes gas dispersed in a solid

On the next slide, you can select any answers you want, or you can select nothing. There's no wrong answer.

A student squeezes several oranges to make a glass of orange juice. The juice contains pieces of orange pulp mixed with the juice. Explain why this drink can be considered a combination of a suspension and a solution.

The juice contains sugars, plant pigments, and other chemicals dissolved in water. This is a solution. The pieces of orange pulp will rise to the top or settle to the bottom of the juice if it is allowed to sit. The pieces of pulp mixed with the juice form a suspension

On the right side, you can also select any answers or none at all. There is no wrong answer.

<h2>Explanation:</h2>

There are two main types of mixtures, homogeneous mixtures and heterogeneous mixtures. The components of a homogeneous mixture are evenly distributed throughout the mixture. The properties of a mixture are the same everywhere. The components of a heterogeneous mixture are not evenly distributed. Different regions of this mixture have different   properties.

Particles in a homogeneous mixture do not settle down or separate when left alone. Particles in a heterogeneous mixture eventually separate or settle when left alone.

  • Colloids are a type of heterogeneous mixture that do not naturally settle out quickly, and can be separated with different methods.
  • A suspension is another type of heterogeneous mixtures in which the components of the mixture will quickly settle out or can be filtered or separated.
