- such protein combinations are sometimes called---->complementary proteins
- also called protein-calorie malnutrition
- seen in protein deficiency
- generated mostly by removal of amine groups from unneeded amino acids or from amino acids being sacrificed to a need for energy
- the progressive discomfort, illness, and pain resulting from the lack of food
- Each has an amine group at one end and an acid group at the other end, and a distinctive side chain
- Protein: compounds composed of carbon, hydrogen, oxygen and nitrogen and arranged as strands of amino acids.
- Amino Acids: the building blocks of protien.
- Amine group: the nitrogen containing portion of an amino acid
- Side Chain: the unique chemical strcuture attached to the backbone of each amino acid that differentiates one amino acids from another
- Essential Amino Acids: amino acids that either can't be synthesized at all by the body or cannot be synthesized in amounts sufficient to meet physiological needs.
- Conditionally Essential Amino Acids: an amino acids that is normally nonessential but must be supplied by the diet in special circumstances when the need for it exceeds the body's ability to produce it
- Peptide Bond: a bond that connected one amino acids with another, forming a link in a protein chain
- Denaturation: the irreversible change in a protien's folded shape brought about by heat, acids, bases, alcohol, salts or heavy metals, or other agents
- Antibodies: large proteins of the blood, produced by the immune system in response to an invasion of the body by foreign substances.
- Fluid and electrolyte balance: the distribution of fluid and dissolved particles among body compartments
- Edema: swellin of body tissue caused by leakage of fluid from the blood vessels
- Buffers: compounds that help keep a solution's acidity or alkalinity constant
- Urea: the principle nitrogen-excretion product of protein metabolism
- High-quality protiens: dietary proteins containing all the essential amino acids in relatively the same amounts that human beings require
- Limiting amino acid: an essential amino acid that is present in dietary protein in an insufficient amount, thereby limiting the body's ability to build protein
- Complementary Protein: 2 or more proteins whose amino acid assortments complement each other in such a way that the essential amino acids missing from one are supplied by the other
- Mutual Supplementation: the strategy of combining 2 incomplete protein sources so that the amino acids in one food make up for those lacking in the other food
- Proetin-energy malnutrtion (PEM): the world's most widespread malnutrition problem, including both marasmus and kwashiorkor and states in which they overlap
- Hunger: the physiological craving for food
- Marasmus: the calorie deficiency disease; starvation
- Kwashiorkor: a disease related to protein malnutrition with a set of recognizable symptoms, such as edema
- Some amino acids contain the element sulfur
Words From Our Students
"StudyBlue is great for studying. I love the study guides, flashcards, and quizzes. So extremely helpful for all of my classes!"
Alice, Arizona State University
"I'm a student using StudyBlue, and I can 100% say that it helps me so much. Study materials for almost every subject in school are available in StudyBlue. It is so helpful for my education!"
Tim, University of Florida
"StudyBlue provides way more features than other studying apps, and thus allows me to learn very quickly! I actually feel much more comfortable taking my exams after I study with this app. It's amazing!"
Jennifer, Rutgers University
"I love flashcards but carrying around physical flashcards is cumbersome and simply outdated. StudyBlue is exactly what I was looking for!"
