Document Summary

Key word/concept list exam 2: exam covers lipids, protein, energy balance and fat soluble vitamins. Forms important hormones (estrogen, testosterone, vitamin d) Increases risk of heart disease (raises blood cholesterol) Transportation of synthesized fat: very low density lipoproteins, ldl, hdl. Combine two proteins (o(cid:374)e that"s deficie(cid:374)t i(cid:374) a specific a(cid:373)i(cid:374)o acid a(cid:374)d o(cid:374)e that has a(cid:374) excess) Marasmus: diet deficient in calories and proteins: symptoms: low body weight and muscle wasting. Kwashiorkor: diet sufficient calories but inadequate proteins: symptoms: bloating, mental retardation. Specific amino acid present in the lowest quantity compared to need. Protein synthesis occurs if necessary amino acids are present. Stomach: denatured by cooking and acid, gastrin stimulates release of acid and pepsin, pepsin is activated and breaks down proteins into peptones. Small intestine: pancreas releases protein splitting enzymes into the duodenum. Trypsin, chymotrypsin, carboxypeptidase: enzymes break proteins into smaller peptides and amino acids, peptides and amino acids are ready for absorption.
