Question

Какие функции выполняют белки коллаген и пепсин​

Answer 1

Ответ:

коллаген выполняет также механическую, защитную, питательную и репаративную функции.пепсин расщепляет центральные пептидные связи в молекулах белков и пептидов (кроме кератинов и других склеропротеинов) с образованием более простых пептидов и свободных аминокислот

Answer 2

Functions of Collagen:

Collagen is a protein that plays several important functions in the body. Here are some key functions of collagen:

1. Structural Support: Collagen is the main structural protein in the body and provides strength and support to various tissues, including the skin, bones, tendons, ligaments, and cartilage.

2. Skin Health: Collagen is essential for maintaining the elasticity, firmness, and hydration of the skin. It helps to reduce wrinkles, improve skin texture, and promote a youthful appearance.

3. Bone Strength: Collagen is a major component of bone tissue and contributes to its strength and flexibility. It helps to maintain bone density and prevent conditions like osteoporosis.

4. Joint Health: Collagen is present in the cartilage that cushions the joints and helps to maintain their smooth movement. It can help reduce joint pain and improve joint function in conditions like osteoarthritis.

5. Wound Healing: Collagen plays a crucial role in the wound healing process. It forms a scaffold for new tissue growth and helps to promote the regeneration of skin cells.

Functions of Pepsin:

Pepsin is an enzyme that plays a vital role in the digestion of proteins. Here are the main functions of pepsin:

1. Protein Digestion: Pepsin is produced in the stomach and helps break down proteins into smaller peptides. It works by cleaving the peptide bonds between amino acids, converting proteins into smaller, more easily absorbable molecules.

2. Activation of Other Enzymes: Pepsin also plays a role in activating other digestive enzymes, such as trypsin and chymotrypsin, which further break down proteins in the small intestine.

3. Optimal pH: Pepsin functions optimally in the acidic environment of the stomach, where it is activated by hydrochloric acid. This acidic environment helps to denature proteins and facilitate their digestion.

4. Gastric Protection: Pepsin also has a protective function by preventing the overgrowth of bacteria in the stomach. It helps to maintain the acidic pH of the stomach, which inhibits the growth of certain harmful bacteria.

It's important to note that collagen and pepsin have different functions in the body. Collagen is primarily involved in structural support and tissue integrity, while pepsin is an enzyme involved in protein digestion in the stomach.
