D. SMALL INTESTINE 1. Name the building blocks of each major class of nutrients: complex carbohydrates (AKA polysaccharides like starch), fats (AKA triglycerides), and proteins. 2.About 99% of all nutrients ingested are absorbed in the small intestine. A. Name the 3 portions of the small intestine in order. The Duodenum, Jejunum, and Ileum. B. In which of these 3 portions does the greatest amount of nutrients absorption occur

Explanation:

1. Complex carbohydrates (AKA polysaccharides like starch)- monosaccharides linked together by glycosidic linkages

Fats (AKA triglycerides) - Fatty acids

Proteins- Amino acids.

2. Name the 3 portions of the small intestine in order - The Duodenum, Jejunum, and Ileum.

3. In which of these 3 portions does the greatest amount of nutrients absorption occur - Jejunum

explanation:

the sequence of amino acids in a protein determines its function. the dna sequence of a gene determines the amino acid sequence of the resulting protein. thus, any changes in dna sequence can result in changes in protein function. this is called a mutation.
