H - Chem - Proteins

What happens when proteins are heated?

• Intermolecular bonds are broken, allowing proteins to change shape (denature).

• Proteins become more rigid and do not change shape.

• Proteins dissolve in water and lose their nutritional value.

• Proteins remain unchanged and retain their original texture.

How are proteins structured?

• Proteins are composed of amino acids that form long chains, which can fold into spirals, sheets, or other complex shapes due to intermolecular bonding between side chains.

• Proteins are structured as simple linear chains of amino acids without any complex folding.

• Proteins are made up of nucleotides that form double helixes, similar to DNA.

• Proteins are primarily structured as globular forms that do not exhibit any specific shapes.

How are proteins formed?

• Proteins are formed by linking nucleotides together through peptide bonds.

• Proteins are made of many amino acid molecules linked together by condensation reactions, where the amino group of one amino acid and the carboxyl group of another join, eliminating water.

• Proteins are synthesized from fatty acids through hydrolysis reactions.

• Proteins are created by the direct combination of sugars and lipids.

What are essential amino acids?

• Amino acids that the body can synthesize on its own.

• Amino acids that must be obtained from the diet.

• Amino acids that are only found in animal products.

• Amino acids that are not necessary for human health.
