Connective Tissue Proteins
Collagen:
- The main representative of connective tissue, also found in skin and bones.
- Contains glycine (30%), proline, and hydroxyproline (25%), conferring rigidity and strength.
- Its basic unit is tropocollagen, a helical structure consisting of 3 chains.
- Features a crystal structure, which might be related to rigidity and resistance to mastication. These features increase with the animal’s age due to an increased number of links.
- Easily
Nutritional Deficiencies, Diabetes, and Biomolecules
Nutritional Deficiencies
Nutritional Oedema
- It results from a long-continued loss of protein and usually occurs in famine areas. Protein deficiency in adults is very rare.
- Deficiency symptoms include weight loss, reduced fat, infections, frequent loose stools, delayed wound healing, and oedema.
- Consuming soybeans, milk, eggs, and other nutritious foods can cure protein deficiency syndrome in adults.
Marasmus
- It is a disease of infants below one year of age.
- Its cause is protein and carbohydrate or other

Carbohydrates: Fueling Your Body
The primary function of carbohydrates in the body is to provide energy. Fructose, galactose, and glucose are examples of monosaccharides, not polysaccharides.
Understanding Sweetness and Blood Sugar
The sweetness in a banana comes mostly from fructose and sucrose. A blood glucose level of 60 mg/dL is considered to be representative of hypoglycemia. In comparison with table sugar (sucrose), honey tastes sweeter because it contains fructose.

Baby Nutrition and Feeding Milestones (0-12 Months)
Alimentation from 0 to 14 Months
Breastfeeding (0-14 months):
- Provides the ideal amount of protein to meet the organism’s needs.
- Reduces the risk of allergies or intolerances.
- Fats promote healthy brain development, prevent high cholesterol, and protect against chronic conditions.
- Adequate amounts of mineral salts help avoid water retention and prevent anemia.
- The Q-factor improves the defenses of the digestive tract.
- Promotes close contact between mother and baby, affecting emotional and psychological
