Study Notes
Triglycerides Composition
- Simple triglycerides consist of three identical fatty acids bound to glycerol.
- Mixed triglycerides are composed of different types of fatty acids, reflecting dietary fat diversity.
Amino Acids
- Non-essential amino acids can be synthesized by the body; alanine is one such amino acid.
- Essential amino acids must be obtained through diet because the body cannot produce them.
Protein Breakdown Function
- The primary function of protein breakdown is to reduce excess ammonia by converting it to urea, facilitating safe nitrogen disposal.
Fat and Energy Metabolism
- Dietary fat provides a concentrated source of energy, playing a significant role in energy metabolism.
- Fats support the absorption of fat-soluble vitamins, though they do not replace carbohydrates entirely.
Lignin and Digestibility
- Lignin is indigestible, resulting in reduced digestibility of various dietary components, particularly fibrous foods.
Digestible Energy (DE)
- DE represents the proportion of feed energy that is absorbed by the animal after accounting for losses in feces.
Proteins and Essential Amino Acids
- The presence of essential amino acids in protein sources signifies that they need to be acquired through the diet.
Challenges in Fat Digestion
- The difficulty in fat digestion in the stomach arises mainly due to the size of fat globules, which hampers emulsification and digestion.
Ammonia in Protein Metabolism
- Excess ammonia produced from protein metabolism is excreted to maintain nitrogen balance in the body.
